Title: 5-8kw Gen Head Australia
Post by: old seagull man on November 05, 2018, 02:17:46 AM
Still on the hunt for a 5 - 8 kw gen head in OZ, closer to QLD the better.
Belt drive..

There must be an extra in somebody shed.

You didn't get one from the guy near Kempsey ?

It seems amazing how hard Gennys are to come by here.

Hi OSM, what happened to the head from Kempsey? Mine now looks petty good (see photos). I have skimmed the slip rings, fitted the new sealed bearings and wired up the AVR. I had to make a new top box for it, as the one it came with was an insult to engineering, a drunken monkey could have done better!

The AVR replaces the old bridge rectifier which used to feed the field winding. I have ordered a new high quality bridge rectifier and heat sink. This will be coupled to the two loose black wires in the photo. in the event of an AVR failure (usually due to magnetic storms) I will be able to quickly connect the field winding (red/brown wires) to the rectifier and be back in business, albeit a temporary fix. If you are in any doubt about these generator heads and the addition of an AVR please check out Benny loves diesels on you tube. (I`m not Benny, so no self promotion here).

I have kept the 32 amp circuit breaker but discarded everything else, as I plan to put a distribution board on the wall above the generator. This will have volt, amp, hertz and mega watt hour meters.

Sorry this is all taking me so long but health issues keep me from doing much. I will keep my eyes and ears open for something that may be suitable for you, is Grafton too far south of the boarder for you?

Bob.

No was all set to go and have had no contact from him.
He was coming up my way with his truck, that was wonderful of him, and we were going to meet and collect, it.
then nothing.
Sent him a few email, even inquired about the 10k he had, but no reply's. I hope he's OK.

So still looking.

Yours is looking very flash, Bob. And no Grafton is not to far. Im shore if we looked in Glort's Aladdin's cave we would find something.

I had the same thing.  Change of plans and I thought the guy must have just thought I was mucking him around too much.

Unfortunately in my Alladdins cave you will find endless crap but a gen head won't be amoungst it.  Plenty of engines, not much to hook them up to yet.
Not really  worried atm. Too little motivation to do the things that  need doing rather than playing around just now.
Even sold one of my engines weekend before last.  Old fella came from over 300Km away to get it.  Didn't even sell it to him, gave it to him actually. Hope he has more enthusiasm than I did with it.

Don`t give up on Stephen, I know he has had a battle with health problems, I`m hoping he`s OK as he is a very nice, honest and knowledgeable guy.

OSM, be careful what you wish for, releasing the Glort Genie could have serious repercussions!  :laugh:

Hi Thanks Bob,

have seen those. gen head and AVR, plus GST quoted me $1475 pick up in Brisbane.
They look like a good Stamford clone, wouldn't say were they were made.
So the search continues, and also thanks to everyone who is keeping an eye out.

Well what do you know.

Stephen contacted me it looks like i might have a ST5 head in a week or two if it all comes together, so might will be out with the notes on your rebuild.
And time to start on mine.

 :) :) :)

Happy Christmas to me

Hi OSM, The new bridge rectifier and heat sink arrived today, way more powerful than needed but $20 for the pair gives me peace of mind in the event of a lightning strike killing the AVR. Probably less than a five minute job to rewire the field wires back to the rectifier and I`m back in business.

I also modified the top box cover by cutting a couple of air vents and covering them with fly mesh to keep out the creepy crawlies. Temperatures in summer can easily hit 50 centigrade here so can`t have too much ventilation.

Interestingly, the generator main body is painted with Brunswick Green to match the Lister engine. I wanted to spray paint the cover of the top box, I found that British Paints make a can of spray paint called Jungle Green which is nearly identical. might help some of our American cousins who can`t get Brunswick green.

Well Santa arrived early at OSM HQ, Stephen met me in brisbane, and delivered me a nice 2010 built green chinese  5kw generator.
Pictures in the morning.

But it looks just like Bobs in the earlier photos. And will probable get the same Avr and bridge pack.
But Digital meters, Glort style.

So i will need a taper lock 140mm pulley and some other bits, as well.

How many drive belts are most people putting on there 5k heads? The engine has a four groove, pulley. So will need to match the section of the pulley and belts.

Any suggestions for drive belt setups, most very welcome.  Its a pitty i can't use a serpentine fan belt from a commodore or falcon and couple of harmonic balancer pulleys.

Bravo OSM, Christmas has come early. For v-belts, pulleys and taper lock bushes, google PTParts. They have outlets in Sydney and Melbourne. They also have an online ordering facility. Their website shows all belts, pulleys and taper locks with prices.

In my case I was thinking to use a twin 250 mm pulley and taper lock bush. I will run either A or B belts straight off the 600 mm Lister CS flywheel. The ST head needs to run at 1500 RPM to give me 50 Hz. The ratios with 600 mm to 250 mm should have my CS running at around 620 RPM. Probably as close as I am going to get without having a custom pulley made.

In your case I think the decision has been made for you by the drive pulley on the primary mover, unless you want the extra expense of changing it.

Let us know how you get on, lots of pics and questions please.

Bob

Hi Bob

Your calcs on the ratio with the belts on the CS flywheel are within an ace of mine, I used a serpentine belt (to a stock pulley) as it's profile fitted  in the space left under the flywheel with the CS bolted onto a bed made with RSJ's. (there's only 10mm or so)

I ended up with 630 ish rpm's, I can load the alternator up until the CS starts 'rolling coal' and there's no chirping or slipping at all. I have no idlers, the tension is adjusted by sliding the alternator back and forth on the bed.

I've not yet run the CS in anger but my feeling is that running 5% or so over the 600rpm will give a little slack when a load kicks in.

Cheers
Stef

Its a pitty i can't use a serpentine fan belt from a commodore or falcon and couple of harmonic balancer pulleys.

Brother in law has finally got around to turning me up a shaft and boring the pulleys I gave him 12 months ago. They are for my China Horizontal so I can replace the original small pulley with.... whatever I like really.
There will be a plate which bolts into the OEM 3 holes in place of the original pulley. the plate has a shaft  welded on which is stepped both for 1" and 3/4"  sizes.  Also gave him a serpentine Harmonic balancer from a Subaru he's going to bore and sleeve to fit the 1" shaft so I will have a serpentine output. This will be mainly so I can run the OEM car alts without having to change the pulleys back to V belt. The harmonic size is Right for what I want to run on my induction motor as well so I might either add the harmonic on the end of the taperlock on there now as there is a heap of shaft length or use the taper on something else.

I bought some V belt B pulleys earlier this year and priced the serpentine's. They were 3-4X the cost. I know they are more efficient, quieter, less maintence etc but the cost of the pulleys and the belts is too much for my cheap arse and a cost i'd never regain.  V belts OTOH aren't  bad at all and are cheap and readily available as are the pulleys. I think if one had a lathe, cutting the serpentine's to make your own wouldn't be hard.

That said, a Lot of different cars use them these days so between things like PS pumps, alts and other things as well as idlers, there should be a good supply at any multi brand wrecking yard and they would never sell them otherwise.

I have been running a B belt in an A belt Pulley on my plough. So far working well and no signs of problems.  I like the way it bites right into the A pulley and certainly no loss of grip there although I suspect the torque is very low given the gearing.  Also run B belts off the flywheel of the lister. Surprised how well that gripped and true it ran but there is a LOT of surface area there. I think rope would probably work on that for the size and power output.
I always go for B belts. Not much more than A's and the size and power transmission difference is substantial.  I think that would also translate into better longevity as well if you ever used the things enough where that was an issue.  More likley my purposes are going to need the belt replaced through age and going hard and stiff more than anything else.

 Hey Glort, how was NZ?

Only 12 months for your Brother in Law to do some turning for you? What I would give for a Doctor, Surgeon, lawyer or insurance company that would act so swiftly!  :laugh:

Like your idea of a stepped shaft to accommodate different sized pulleys for different applications. I was considering some sort of a lay shaft to drive various demands, I may have to think again.

I will probably opt for twin A belts as the cost of a 250 mm twin B belt pulley will buy a lot of A belts. I`m not a tight arse by nature but I`m facing multiple surgeries to repair injuries from the accident. Very unlikely I will be able to work for at least another twelve months, so got to be very careful with the pennies. Very aggravating having all this time on my hands and no money to do any of the things I want doing, even if I briefly feel well enough to do them.

Hey Stef, glad you concur with my calculations, I suspect that there will be some wear on the belts so RPM may have to be tweaked a bit during regular maintenance. I was going to aim for 51/52 Hz unloaded expecting things to drop a bit as I up the demand.

I was thinking to make a tensioning system similar to the one in the photo, just bigger and stronger. I made a pair of these a few years back after the local village water pump motor got washed away in a flood event. The river rose by 24 meters! This one is the spare and has been in my shed ever since.

Hey Glort, how was NZ?

Was many things Bob, Very beautiful for sure. Somewhat backward, frustrating at times, great food and wine, Very scenic, Fun, scary, painful, annoying and did I mention the great scenery??

3rd trip there but it's amazing how much you forget in a few years. Was weird. We could remember a lot about our first trip but none of us could remember beans about the 2nd one. We have been racking our brains where the hell we went, what the hell we did. The HDD with all the pics of the trip on it has a corrupted MBR I have to fix so for the moment, we can remember what we did and where we went 6 years ago with great clarity but it's like The 2nd trip 4 years ago was a figment of our imagination.

Not sure if I'll go again.  All in all it was a bit too painful for me but the Mrs and daughter enjoyed themselves so that's the main thing.  I was amazed they couldn't get another shooter in NZ to do what I do but then the guy I work for showed me what the guy last year did when I couldn't go and then I understood.

Time moves slow in the medical/ legal/ insurance world. Don't ask me how I know. Don't want to think about it.
Annoying thing with the BIL is the trade off favour for him doing this had to be done asap and I got a lecture about it.  I always do things for people quick as I can because I know how annoying waiting like I have is. Unfortunately they sometimes fail to have the same consideration.

Mate not far from me bought a lathe the other week.  I helped him put it in and he was more than happy for me to come use it any time I want. He said he needs it but it won't get used often but as something for the business and the fact he has to get things done quick, it's worth it.  I haven't seen what tools he has for it yet but even if I have to buy some to do my own work, will be well worth it.

  I have amassed a bunch of pulleys and what ever one I want for any job is always the wrong bore size.  I thought this way I can accommodate the majority of what I have and as the engine could be used for various things, it was the easy way of making it as universal as possible.

I need to do another one for the 30 Hp 2 Cyl Ruggerini I bought earlier in the year. That thing has an SAE drilled and tapped flywheel drive and a PTO plate/ shaft for that is $300 to buy.  Cheaper to have an engineering shop do it and cheaper still to use the steel I have or even cast up something in aluminum and make my own. 
Speaking of which, BIL wants me to cast up some aluminum parts for him but that won't be happening anytime soon. I don't have the time and where I am, I can't go firing up flame throwers with the fire restrictions apart from the bad idea it would be anyhow with things being so dry. Lot of things I want to get done here before Christmas and that's going to take all the motivation and energy I have.  Right now frigging round with burners is not something that I could be bothered with.

I didn't realise there was a significan't difference but then again, never compared either. Twins make a big difference to singles anyway.  Mate was in power transmission years back and on occasions would hire me to take pics of things in quarry's, mines and factories. Loved those jobs, very interesting.  Some of these motors had 8 or 12 belt pulleys on them.  Idea was they could loose at least half and still not worry. Every year they changed them all out with the yearly maintence.
They look simple but when you get up to that level things get pretty critical and precise.

I'm real sorry to hear that Bob. I thought you were over the worst of it and on the mend. I hope it all goes as well as possible for you.    At least you will have plenty of time to impart your vast wisdom on things here. Like Ed and Bruce and some others, your " rants" here as you call them are things I learn a lot from and feel smarter from having read them even though you guys often dismiss their good value. If talking about things is a help to you at all, I'm always happy to be a sounding board for you privately or publicly. Don't know there is much else I can do for you but if there is, you just let me know.

Yes, been there, done that for a long time. But I think there is something worse.
Having the money to do things but not having the inclination or motivation to do be fussed with anything you would have jumped at  some years earlier. 

I went to the doc the other day.  Apparently I'm the healthiest I have been in a number of years. Apart from my Diabetes which is doing well, I'm better than average for someone my age... as hard as that is for me to believe. Unfortunately my head is lagging behind my physical well being badly and not coming along as it should.  No surprises there. It has really been getting me down latley.  There is a lot I could do but I just could not care less about anything. I have been so tired and lacking in energy and the doc puts that down to depression rather than a physical problem.  Had someone told me they had this a few years back, I would have dismissed them as being many uncomplimentary things but now here I am. Maybe it's just Karma at work.

Spose you put the 2 of us together like a couple of old cars and you could make one good one.  If only it were that easy.



That tensioner reminds me of a Sawbench my grandfather built when I was a kid.
The motor was Hinged at one end and it's own weight was the tensioner.  Everyone told Grandad what was wrong with it which I think he liked as he would pull out some thick lump of timber and shave off a slice to show them it worked perfectly.

Something similar where the driven load was fixed and the motor was the hinged part using it's own weight for tension might be something worthwhile in some applications.

Hey Guys...

Unless you want to become unhinged by the rattling and driving yourself nuts with that sort of tensioner on a "one power stroke every 4 days" style engine, rather opt for just the 4 slotted holes and a couple of jack bolts to tension the belts...

I tried one of these on one of my TM's a while back and it drove me nuts with the rattles....

Just my 2c worth, probably not actually worth that much too....

Cheers

Hey Buddy and welcome back. I`ve missed you and I`m sure the rest of the forum have too.  I`m very glad to hear you had an OK time in NZ even if it has thrown a bit of a fruit loop into the equation regarding previous visits. I went skiing in the Alps every year, for twenty years, with my Wife and family and none of us can agree on exactly which year we did what. Don`t worry about it, remember the good stuff and F*ck the rest of it, life`s too short. Very pleased to hear your Wife and Daughter enjoyed the trip.

With regards lawyers and etc. I think glaciers melt quicker , the question is will I be killed by old age or global warming/climate change before I get my day in court to sue these b*stards!

Very pleased that a mate of mine also bought a lathe a while back, with tooling. Its only small so I`m limited in what I can do but what an enormous saving when it comes to replacing bushes and etc. I would dearly love to have a milling machine, lathe and broaching press in my shed but the costs are prohibitive and I`m probably too crook to make worthwhile use of them. I do miss the equipment that was available when I was in the RAF, we could make anything and we did, up to and including a new bonnet for an E type Jaguar.

Pulleys, what a pain in the arse! Why can`t we standardize things? We have too many standards, Imperial/Metric and then all the weird and wonderful sh1t coming out of the third world. Confused? you will be!  :laugh:

The difference between A  and B belts is in their strength and contact surface area, B belts for heavy loads. For a six HP  Lister CS engine, twin A belts and pulleys are a cheaper option and will probably still be going when I am long dead.

I`m with you on the issue of money and no inspiration as apposed to inspiration and no money. We need to either get together and be brilliant/successful or sit on our arses and do f*ckall in tandem!  :laugh:

Thank you for your concern for my health and well being, I guess we have to play with the cards we`ve been dealt, even if it drives us half crazy. When I watched some of the guys in the Invictus games it made me feel quite ashamed that I can`t overcome my PTSD and anxiety issues when these blokes have been through much worse than me and are embracing life. I always thought I was tough until I watched them!

Not sure what you would end up with if you tried to build one good man out of two f*cked up ones, were you planning to build one very f*ucked up one out of what was left? Thank you for that thought, best laugh I have had in months, my wife now thinks I am even more strange.

Bob

Post by: glort on November 23, 2018, 08:26:39 PM

I did enjoy parts of the trip. Shooting the work was a bore but thankfully it was much easier than I expected. In Sydney the weekend before they were running 300 routines a day. In NZ i'm not sure of the number but I'd guess it was 100 or less. Walk in the park compared to what I have done before.

A highlight was working with the stripper girls and not for the obvious reasons. Got some great pics which gave me a much needed shot of Motivation  but they were the dead opposite of what I expected. HIGHLY intelligent girls, polite and well mannered beyond belief, very cultured, professional and respectable. Polar opposite of the pre conception I had in mind. I was thinking unmarried mothers with 4 kids to 5 different fathers and got Royal Princesses.

They were just enjoyable people to hang out with and even the Mrs and my daughter enjoyed their company when we had drinks and dinner after the shoots.  For the 2nd one, we all met up in town afterwards as the girls wanted to show us this Nice Italian restaurant  they knew of and insisted on paying for us at the end in return for me doing their pics... which I was already paid for but they wanted to do it as their thank you which was incredibly kind of them I thought.

 Their occupation sounds very seedy but these girls were some of the nicest and most refined people for their age or any other I have met.
They want to come to OZ and Mrs said you are welcome to come stay at our house for as long as you want and my daughter said yeah, I could see myself becoming close friends with them and them fitting right into our group.

Talking to them was very interesting and enlightening.  Certainly I would not be thrilled about my daughter doing what they do  ( and neither would she thankfully) BUT, these kids are earning $3K a week on a bad week and $3k a NIGHT on a good night. And they don't do anything other than dance round in their birthday suits.  For what they do, I was surprised at their Genuine high moral standards.
Not sure I could dance round in my birthday suit for $3k a week. Imagine the sick puppys that would pay to see that! AGGGHHH!
Pretty young Girl be a different matter.  :0)  I must go to a strip club one day and put that on my bucket list to see what all the hoopla is about and do what every other bloke on the planet seems to have done that I have never bothered with. Must be something to it?

The scenery in NZ I found amazing. It just never stops.  We would get in the car and go a few Km, if that and then stop to get out and look and take pics. bit further down the road and there was something else you couldn't go past. Went up to the bay of Islands and the Mrs booked an afternoon trip for us that was well over $300.  I thought Hope I don't regret this. Do it again in a heart beat. Fantastic.  Going out the weather was shitty amd there were storms blowing in. Just made things look more dramatic.  2 spots of rain and then the sun came out just as we arrived at the Highlight destination, hole in the rock.  Could not have been better.

So much of the place is relatively backward though.  Crappy old places everywhere with million dollar views... often right next to Multi million dollar homes. Don't know of anywhere you could get views likie hundreds of these crappy places have here for less than a fortune even in the middle of no where. And being NZ, you are never more than 2 hours away from a main city..... well as main citys as they get there. More like Suburban City or country hubs here.
Sydney Airport, 65 gates. hardly anything exceptional. Auckland Airport, 16.  Sydney Population, 3m?  Entire NZ population, 3m. Says it all really.

The amount of asians and Punjabs there stuns me though. They far outnumber the European and native Marois put together. I find that sad really. Like the country has lot a lot of it's identity although they try hard to embrace their culture but in reality, the Asians and Punjab couldn't care less and are hell bent on making things like where they came from rather than giving a damn about where they are.  A lot of them are really only using NZ as a backdoor to easier immigration to Oz anyway.

I went to some gun shops to drool over what they have there.  Racks of AK's, AR's and about anything else you could want.  guns are reasonably priced, ammo is a fortune. The thing that was clear though was the reflection on the culture.  Licencing is pretty basic there, long as you are not a crim you can get what you want with little problem or fuss.  there are all sorts of things out there but unlike other places, there isn't a problem with gun crime, shootings or anything else.  Backs up what I have always said, these shootings and things people blame on guns are not the fault of the tool but rather the mentality of the person holding onto them.
I think owning a Silencer here is about 5 years in the pokie. There they sell them on a LOT of packages where you get the rifle, a bipod, scope, spare mag and the Silencer.

I can only assume they are not worried about hit men ruuning round offing people because it rarely happens but scaring the sheep is a problem they won't accept!

I found another complication to Pulleys a while back. That 2 Wheel tractor I was going to convert to diesel..... I got the diesel engine to replace the petrol one that has been working so well but came unstuck with that. 
It's not a 3/4 or a 1" Shaft or any metric equivalent on the Diesel... it's 20 MM, another size again. The other engines I have the same are 3/4  or 19.05 mm so they decided to change that somewhere.  So far none of the industrial suppliers I have contacted have that size and neither do the people making the pulleys so it's a matter of buy a blank and bore it or get it bored. It never bloody ends!


 
People that have had no problems have no idea of what people that have go through and their sense of values are frequently off IMHO.
While we bitch, there are people like Bruce that probably think  I'd like to be as well off as you fkers are.  It's all relevant I think. There are many difficulties of many levels and you have to have walked in the persons shoes to really understand them.

I'm with you on the anxiety. I was nearly throwing up for a fortnight before we went. I had a churning feeling in my stomach, a dry mouth and a sense of impending doom.  When we were there, several times I though I was going to fall over. I would see something where we had been before and it was like a memory and reality merging into one in my minds eye. The memory of the past and who was there just hit me like a wave and a couple of times I did actually stumble as my legs went weak and my heart started to try to pound through my chest.  Then I was left trying to fight back the tears and not upset the Mrs and daughter.

And people look at me strange when I tell them I prefer to just stay at home.

Seeing we are talking Miracles about one good one out of 2,  we might need a 3rd person in on this as well as I'm not sure that the pair of us have enough good working parts to make something that would pass a rego check and be road worthy.

NZ population just hit 5 million recently

Ethnic diversity?  Let me quote from the most recent (2017) stats below:

The majority of New Zealand's population is of European descent (74 percent), with the indigenous Māori being the largest minority (14.9 percent), followed by Asians (11.8 percent) and non-Māori Pacific Islanders (7.4 percent).
Minor ethnic: Māori 14.9%; Asian 11.8%; Pacific peoples
Major ethnic: European 74.0%
Population: 4,885,300 (Stats NZ 2017 estimate)

Post by: glort on November 24, 2018, 06:22:41 AM

I would gaurantee that ethnic breakdown does not apply in Auckland that's for sure. Maybe as an overall but not in the main city.

I was so amazed at how many Asians and Punjabs were there, I did another Video of people just walking by in a couple of places.  Clearly shows how few Europeans and Maoris are there over all. I did see more Maoris further out, they have a lot in common with our Aboriginals.

On our last day in Paihia, there was a geriatric invasionand coup attempt. One of the Princess line Cruise ships came into port and shops that had not been open in the time we were there were suddenly open and well staffed.  The amount of old fogies hobbling round was scary and the smell of Dencorub was thick in the air. Geez old people en masse are pains in the arse! Move like tired snails, always seem to stand in the middle of things so you can't get past, can't make a simple decision between Passion fruit and vanilla and are a terrible reminder of what the years ahead hold for us heading that very same way.... if we make it that far.

The whole trip my fashinista Daughter had been at me for what I had been wearing and complaining about what I was going out in. Made me change a load of times to co ordinate better so I was fit to be seen in her company.
After seeing what these old buggers were wearing and how ridiculous some of them looked, I thought maybe having her nag me isn't such a bad thing after all if it stops me going out in public looking like some of these blokes. The women were OK but I was left to wonder if they had any mirrors in the cabins on this ship or all the blokes were bind were all blind and dressed themselves or selected there attire for the day in the pitch dark? ?

Mrs had been talking about our next holiday being a cruise but I told her, there is no way i'm getting on the good ship geriatric until I'm well and truly one of them and a lot further gone than I am now.
My daughter suggested the alternative was some booze cruise where they partied all night and I'd never get any sleep. I said that would suit me fine! I never sleep at night anyway and at least there would be some young people to talk to rather than old fogeys recanting stories of the good old days when bread was  5 Cents a loaf and when electric lights replaced the gas ones in their family home.  Bugger that. 

Maybe the ethnic demographics change a LOT from area to area but the numbers in no way reflect what we saw in Auckland and surrounds.

5M people 'eh?  I guarantee there are 2M of them all trying to get over the Auckland Bridge on a Friday afternoon. How in hell can traffic move so slow over good 6 lane highways when there are so fe people in the city to start with and no breakdowns or accidents? Bad as Sydney with shit roads and many times more people.

Americans couldn't survive in NZ. they would have heart attacks. Petrol was $2.36 Liter/  $8.97 a gallon when I was there. 
Americans want to invade Canada to take the oil when fuel hits $4 a gallon!
While the majority of cars are small 4 Cyl jap imports, there are still a lot of people running full size Australian 6's and V8's.  Probably explains the level of much of the housing there. Nothing left for a decent home, all goes on fuel.  A lot of euro luxury cars there too so a good number of people there are doing real well.

The Pictures..

As you can see the head isn't that bad and the wiring, is not that fantastic, but its all there.
So im looking for a 38mm taperlock bush with a matching 140mm 3 section v belt pulley.
and will start with two belts, and go to 3 if needed. Cant see i would need all four.

An suggestions on ebay AVR's was thinking SX 460 or something like. Or are they only for Brushless heads?

So thats were it stands at the moment. May replace the top box with something bigger and put the power sockets on one side and the meters and breakers on the other.

The consensus on ST heads for stationary use is to remove the doghouse and replace it with a smaller box for electrical interconnect only, and move your electronics to a wall mounted box.

I did that after watching the the usual failures. (We all want to believe it can't be that bad.) I used a die cast aluminum box that just covers the top opening.

The stock analog meter typically fails within a few hours of run time.  It's a very high vibration location.  If it is for a portable rig, I'd still remove the doghouse, and would not mount even digital electronics in that location.

Hi OSM, when I bought my head, Stephen threw in a GAVR 15B AVR, looks to be an OK unit although the wiring diagram is a bit confusing. Cheapest I could find on fleabay is this one https://www.ebay.com.au/itm/Universal-Diesel-Generator-Part-AVR-GAVR-15A-Automatic-Voltage-Regulator/122996408286?epid=2286885748&hash=item1ca3283fde:g:kg0AAOSwSP9bUaiE:rk:59:pf:0

Is the pulley on your engine for an A or B belt?

Totally agree with BruceM about vibration causing problems. Once I get around to building a permanent home for my CS and generator head I will be moving every thing onto the wall.

Hi OSM, measure the width of the grooves at the widest point, A belts are 12.7 mm wide, B belts 16.7 mm and C belts 22mm.

Hoping it`s an A belt pulley as B and C belts and pulleys are a bit pricey. When I as working in the Boral sawmills we standardized everything to run A belts because of this. Everything except for the waste chippers which ran six 5 meter long D belts, these had to be exactly matched in length, if one belt got damaged we had to change all six. Very glad I wasn`t paying for them!  :laugh:

They seem very good prices Bob. Where did you get them from?

The A/B prices don't seem that much different to me. I also note one would pay less for a B triple than an A quad. have to compare belt prices as well but 3 against 4 may hedge the costs there some as well.

I'd think for the job,  single and Doubles would be more appropriate, Doubles and triples at worst.

I was "talking " to some guys on the web last year whom are into those high power stereos and run 4 and 6 300A alternators.  What a bunch of pelicans those guys are. Noise must have affected their brains as well as their hearing.   All insisted they NEEDED all these alts but then when given the specs of the system they didn't come near the power draw they insisted the alts had to provide.

They were talking about the serpentine belts not lasting long and a quick lookup showed why. I forget the numbers now but each bend and each tensioner reduces the power carrying capacity of the belt.  Just having all the alts and idlers nearly put the belts beyond their limit for normal use.  Expecting them carry even half the load of all the alts was waay beyond their power carrying capacity.  Trying to point that out was like trying to tell them all the alts were unnecessary as was the suggestion that if the noise competitions went for under 5 Min, they would be far better off with an extra battery than a bunch of alternators.

But what would I know?  I was just going on facts and figures and laws of physics. No room for that when you are trying to make yourself and everyone else within half a mile deaf and showing off is more important than any sort of sound engineering.
Some of those things had Alt setups capable of delivering over 15 Kw!

Those Serpentine belts MUST be strong to carry the loads these pelicans put them under at all and don't just snap straight off being so over loaded.

I will measure the pulley on the engine in the morning, im in the middle of a 18 hour work day at the moment,

Hi Guys,take a look at this link. https://www.ptparts.com.au/
Outlets in Sydney and Melbourne free delivery on orders over $50!  :)
Very nice website with lots of information, prices and you can order online. Just what the internet is supposed to provide.

Don`t understand the idea of a motor vehicle with a stereo system that can only be safely listened to two states away, in a sound proof bunker! As for the alternators to power these wretched things, I suspect there is a forum somewhere feeding them the wrong information so someone can make a fast buck.

Sadly these guys grew up watching Startrek and other science fiction movies, They didn`t study at school and don`t understand the laws of physics. They think the equipment they are buying now is expensive, just wait till they have to fork out $80,000 for cochlear implants so they can hear again!  :laugh:

Pucker up Bob!
I want to give you a big kiss on the lips for that!   :-*

I never heard of these guys although they are part of Naismith which I thought was a manufacturer/ importer not a retailer. 
Their prices are the best I have seen. Cheap as chips.

I see the belts are a bit more exy in B over A series as you said. Still like the B's though! :0)
The prices on their taper locks are so cheap! Not that far from what I have been paying for ordinary cast ally Pulleys. Made my week with this!



 Don't get me started on the stereo guys. All doof doof so they cannot hear any other frequency at all other than the panels rattling and the windows breaking or falling out.  they must have thick skulls indeed to think that's anything to be desired.

I watched Star trek! I think you are wrong about that, the guys that watched star trek were the ones that learned about Physics. The ones playing shoot em up video games were the the ones that went on to think their car making one monotone racket louder that a screaming 727 on takeoff was a good idea.
So many of them have video game consoles and screens in their noise makers and are still playing them when they are 30 yo.

Measured the engine pulley this morning;
Top:17mm
Bottom:7.5mm
Depth:16mm

So i'm guessing a "B" Pulley or the Chinese version of one.
Though its a machined pulley no a cast one as i have seen on other engines.

So it time to order a pulley, so 2, 3, or 4, grooves is the question.
leaning towards 2 or 3, can't see me needing 4 belts for 10kw drive and 5kw load.
And its not like i wont notice a broken  belt, so i don't need the redundancy, that 4 will provide.
Im leaning towards two and i might use one at a later stage to run a small alternator for battery charging..
Title: Re: 5-8kw Gen Head Australia
Post by: ajaffa1 on November 26, 2018, 02:48:58 AM
Hi OSM, how are you planning to tension you belts? This may sound like a stupid question but the more belts you run the more tension you need to apply, this will have an impact on bearing life expectancy. I`d be tempted to get a triple B belt pulley and just run two belts, if slippage or rapid belt wear becomes a problem you can add a third belt later.

I`m going with a pair of A belts running on the CS flywheel and a 250 mm twin pulley. lots of surface area in contact with the belts so I doubt slippage will be a problem. Large bore single cylinder engines accelerate on the power stroke and decelerate on the compression stroke, this can cause premature failure of the belts and also causes flicker in ST heads without auto voltage regulation.

Bob
Title: Re: 5-8kw Gen Head Australia
Post by: old seagull man on November 26, 2018, 05:04:51 AM
I'm stuck with the "B" belts unless i change the engine drive pulley. Was origionally looking at 3000 rpm alternators, and was going to use long "A" belts like your self and wrap them around the flywheel.
But the arrival of an ST5 1500rpm put an end to that.

Belt tension was going to be elongated slots in the base plate. It has to be simple.

And might build a wooden base just to set it all up, just to make shore everything works.
Title: Re: 5-8kw Gen Head Australia
Post by: ajaffa1 on November 26, 2018, 06:29:55 AM
Hi OSM, like your keep it simple approach. You might consider adding a couple of jacking screws to help with tensioning and alignment. B belts it is, probably worth getting the triple pulley, depending on your finances, gives you that extra bit of redundancy depending on how often you plan to run it.

I sat the bits in there approximate positions in the drive to work out pulley centers and belt lengths.

I'm jealous of that engine! The ones I have in smaller versions are rippers.

In case you are not aware, those mounting legs are for transporting the engine only. They are not meant  for the engine to operate on. there are many tales of woe of people using them and having them fail with very unpleasant consequences.  If you have not already, make up a new sturdy mounting set that can take the literal hammering they will get from one of these mighty engines.

With that nice water cooled type Flywheel, You could also set up a 12V alternator with a serpentine belt to run off that side. Being nice and large it would spin up an alt real well even at low revs and give you a heap of power for battery charging or low voltage applications.

Looking forward to the vid of it set up and running.  :0)

One thing i have to say is the engine runs a lot smoother than you Guys lead me to believe it would.

I clicked on teh vid before I read the rest of your comments.  First thing I thought was geez, that thing is smooth!  I wouldn't expect  those design engines to run like that based on my own experience and every other I have seen vids of. I think you got a good one there and it seems to like the veg oil as well.

Interesting Vid as simple and straight forward as it was. Look forward to seeing it hooked up now even more. I certainly don't think you are likely to have flicker problems with that little turbine.

It is a nice runner- and compact enough to be a "pull out to run" backup generator. 

My neighbor has a cheap 4KW propane generator as a backup for his propane modified CS 8/1 clone housed in a Rubbermaid Deck Storage Box.  The box must be opened and the generator set pulled out slighly for operations.  It's all wired and plumbed for propane, and he has a switch to select CS or 3600 rpm screamer.   He also uses it for his portable power needs with a 5 gallon Propane cylinder.

I also have my 4KW backup gas screamer in a deck box outside my Listeroid 6/1 engine shed, all wired up.  I have never used it beyond testing.  The Rubbermaid boxes are surprisingly durable, mine is over 10 years old and I stand on it monthly for radiator fill tank service.

Once upon a time electrical reticulation here was seen as a service that had to be provided by government for the good of citizens & development of the economy.  Over about 70 years it has changed into a commodity that can be sold to those who can afford it, is out of reach of those who can't, and is generated and distributed by large companies whose first obligation is to make a double-figure return on investment to shareholders.  Sad days

The power Co's have successfully won over the soft of heart and head now to think they are hard done by.

For the last few days I have been watching and talking on another site where idiots there are pushing the idea that people with solar should pay more on their power bills to offset the cost of power for those that have no solar and to "Be fair" to the power companies whom have to maintain the grid and do all the admin work in running their businesses.

They are also Championing that the " Supply charges", the price you pay to be connected to the grid, should be higher to offset price increases in the energy used because it's not fair to the power cos that people have holiday houses or other low use connections and the poor grid operators have to pay for and maintain a connection without getting much return. They make out like the power cos come out every week or month to service them instead of every 20+ years from what I seen.

Several posters were saying that the power cos were wanting to charge them, up to $50K because they were the last ones to build in the street, the PC's said all the allocation was taken up and they would have to pay for a transformer to be put in..... that would then do the whole street.
Some how these Brain washed Koolaide drinkers think that's fair and as well as paying for the maintence, the power used, getting a low FIT on power they send back, people should also pay the full cost for having power connected because the power co's stuffed up on their calculations and won't connect the last guy.

Cry me a freaking River!   ::)

We are not talking about a charity here struggling to feed the homeless, we are talking about greedy corporations posting Millions in profits every quarter.
Nothing like the bleeding hearts carry on about must make money to survive to provide the service or we'd have to live without power supply.
The gullibility of people these days is just plain scary!

Can't wait for the supermarkets to complain about their profitability and they need to double prices in order to make better dividends for their sharholders. No doubt the Numptys will think that's fair and support it as well.

That said.... I did say on the thread that those that felt they would like to express their gratitude to the power co's and make sure they stayed in business would no doubt be welcome to make donations to their profitability. I asked who would like to contribute a donation we could pass on with out thanks for all they do and help keep prices at the same level for those without solar.
Surprising while many parts of my post was quoted and challenged tot he effect we should pay more, not one person, even after being reminded again, wanted to make a donation.

Morons!

On oone hand we are browbeaten about saving the planet, reducing emissions, getting off the devils fossil fuel and all the rest of it, then on the other the power co's are doing all the can to stop the average person doing the one thing they can of any significance in making their own clean power.

And people wonder why I have nothing but Contempt for the green movement, Big Biz and politics.
It's all a joke and insult to ones intelligence.

Well progress is slow, but today OH&S was closed, so i had the Proof Of Concept run.
No OH&S inspectors in site. Wife on a Christmas cruse with the sister and all the kids.

The Pulley came from a bearing supplier here in Brisbane, and when he heard what i was doing he though in the belt. $55.
Gates one too, nice your man. Pulley is 160mm, so at 1500 rpm the engine is doing 1760 rpm. the balancer shafts in the engine seem happiest at this speed.
And the temp didn't change much. Load was a 2400 watt heater. ran for about 15mins before the rain, ended play.
See voltage on the meter on the dog box, and we all know meters don't lie.
So the next step is the AVR and its box, and build a frame.

Thanks to everyone for the finding and scanning and posting. That gets me on the right track.
What im having trouble with is the settings on the AVR.

There are three pots labeled VOLTS STAB and U/F and a Red Led.

Volts:  I'm guessing that with the prime power running at temperature and the generator running at 1500 rpm i set this to give me 240 volts. (Volts makes seance)

Stab:  Guessing that i load the generator up and and adjust this till i have no drop in output voltage as i  increase load? (Stability off the output is what i guess this sets)

U/F: To set the uf knee point This pot is covered so I'm guessing its already set to were its supposed to be?

And what the led is for and what settings it relates to i have know idea.

The saga continues. ;D

I think for fine tuning, you start with the RPM close to 1500, and adjust it till your frequency is correct at about 20% load.  ( 60 hz or 50 hz ) Then at that frequency, you adjust the voltage to where you need it to be.  I see about a 4 hz swing in Fq from no load to full load in my system.

Happy Easter to all.

I got sick of waiting for the welder to do his thing, and i had wanted to knock up a test stand to see it all working, so here is the video.
Sorry shot with a old phone, because Im  an old man. Avr Box and panel still to go, but progress is being made. Slowly.

Nice to see something like this running.
You are aware that is is said those legs on the engine are for packing purposes and are prone to failure if used to mount a working engine?

Figuring out Mounts for a couple of my engines has been quite a procrastination.
Mounted one on an old Tyre the other week to see how much it was going to vibrate.  Tyre at least stopped the thing skating across the floor.  Wondering about using 2 Tyres with some beams across as a mount  With about 250Kg of engine and generator, not sure about that either.

Yes got sick of waiting for the welder.

I Asked the manufacture about the legs, as everyone has said to me there only for shipping, but Shifing the engine builder, say there ok to use and most Chinese generators use them with thousands of hours on them.
But let me know what your using. As i hope one day to get the real frame from the welder, sooon? Had been thinking about using car engine mounts of some kind. 

Thanks for the good words
