Hey Glort...

A brief look at a few cutaway pics on the net suggest that the end of a camshaft with an external old school distributor might be the easiest....

Generators / Re: A hypothetical generator application
« on: January 22, 2020, 07:54:16 AM »
An accumulator in a hydraulic motor environment can be a PITA.... As the bulk of hydraulic motors off the shelf are rev/flow coupled, an increase in speed might be a problem as the accumulator unloads through the motor, particularly if motor torque varies, such as used on a power saw. This would require a somewhat more upmarket motor with a built in "governor" or a flow control valve directly before the motor....

An easier solution might be to have two generators, the smaller one being a prime, the second, larger being an induction generator permanently coupled to the network. The induction could be on a slip/one way drive, allowing it to sync and freewheel with the mains when it is out of use... As net load increases, the second generator can come up to speed with only a small bit of current sensing circuitry to up the governor, thereby assisting the prime mover....

My .0000001c worth....

Listeroid Engines / Re: Idler gear wear pics

Hi Dave,

A brief look at the pics tells me you should either replace the steel gears or spend some long, careful time with a file and emery cloth to dress and clean up the tooth pressure faces... They're chewing up the brass gear quite efficiently...

Mesh looks a little loose, it could be improved upon, but the machining marks on the steel gears are "quite bad" to put it gently....

My not even .0001c worth...

Hey guys,

My less than 1c's worth....

I cold fuge my oils, granted they're WMO, slightly thinned with waste mineral turps, mainly fuge'ing to remove solids and water. The turps originates from a chainsaw wash bay, full of sand, metal filings, water, dust and goodness knows what. The WMO is from various backyard sources, mystery oil, gearbox, sump, diff, grease, dead kittens and puppies included.... This oil goes mostly to my burners these days, but I wouldn't hesitate to run it through the listers in an emergency...

Home made Hi-G fuge, single pass, low flow rate (its a tiny little fuge with the cup being less than 100dia and 100high...

The oils, on exit, are cold, the housing of the fuge barely warm... The air pressure in the fuge is slightly below atmospheric... During spinning of very wet oils and waterlogged diesel, I set the feed flow rate to just borderline water vapour expulsion.... This is not hot steam, but cold mist that emanates - I have some theories as to why, but no substantiated proof as such. At this flow rate, the spun product leaves the unit with little to no water content. But, it is a slow process... My targets for fuel production are but 3 to 4times my consumption... Meaning that I have a scaled down micro version that outputs about 10-20L per hour, depending on contaminant levels... (This is sludge we're talking about here...)

On polishing diesel or other liquids without heavy contamination, I could up the throughput substantially, as I have done in the past.... (Less than a 1% water/contamination level by volume)... The output product is significantly cleaner than store bought fresh diesel when viewed under a microscope.

As to energy usage - 100 to 150W, a little more when the scavenge pump kicks in, easily supplied by a small inverter/toy solar setup during daytime, load on a genset for night operation during emergency is more than tolerable as I use a VFD to control the fuge with soft start/stop... So, after a whole lot of rambling, NO, its not "heated steam" but a cold mist, keep the g's high enough and the flow within the limits of the cup, and you don't need to heat the input product either..... Well, not me, anyway.... But then I do everything arse backwards.... LOL....

Hey Glort...

Glad to see I haven't broken your sense of humour yet....

TM3 is arriving, delivered, at around AUD450 at today's exchange rate.... plus, with it, is about 150L of mildly water contaminated diesel that will go through the 'fuge and get burnt in one of the whirling dervishes.....

TM1 is still staring at me dolefully minus his lid, lid's done, just need to find the time to pop him a new barrel and rings, also waiting.... Life has got beyond me!

TM2 is running fine, taking the brunt of the longer outages, the little autostart and solar are doing the shorter stuffs...

As to the MG42.... I wish....

What I have gotten quite deep into is the cad/cam side of things, unfortunately the grey matter takes a while to charge up nowadays and the things that used to seem quickly "grasp-able" take a wee bit longer now..... No matter, I am not slower, just more deliberate and thorough.....

One thing that has been interesting, with the 3d printers that is, is the interest from the happy hippy home-maker crowd in some lithophanes that I 3d printed... Take a look into it, it would go hand in hand with your photography side of things, and, even me who is less impressed by a scenic panoramic view than the tech involved with making a box of matches, finds them pretty damn awesome!

But, enough rambling.... Gotta go and clear the path for the honeysucker that's en route to alleviate another minor irritation... but that's another saga entirely....

Have a gr8 weekend...

Hey Guys...

And now for something completely different.... A (mostly) "on subject" Lister based post....

Without hoping to jinx the winds of fate, one of my minions is en route to go and pay for a Lister "Barnyard Find".... Hoping to take delivery of it early to mid next week...

So far, all I have seen is pictures, but it seems pretty much intact... It's an original 6/1 with original (as installed) alternator/genhead... The paintwork is non-existent, there's a lot of surface rust, but according to the chap that looked at it for me, a weekend or two of tinkering should get it up and running... Apparently it was mothballed a few years back, read that as about 30, when the premises went onto the grid and has not been used since... It was running till the day that it was shut down, no mech failures to note, that he is aware of, anyway...

Picked it up for a song, at worst, I will have a large driveway ornament that didn't cost too much... Lets see what transpires...

As usual, please excuse the crappy quality pics....

Keep it spinning....

Cheers
Ed

Hey Glort...

Tie male appendage to rope, tie other end of rope to one carbon rod.... When sparks and suchlike become too concerning, apply feet to ground... Rapidly... Ensuing escape will automatically widen spark gap, break conductors and shut down current flow....

PS - Remember to check that the breaking strain of rope is withing personal physical tolerance limits and greater than breaking strain of connected wiring... Electrical, that is!!

General Discussion / Re: Welding on clean DC
« on: October 14, 2019, 10:48:03 AM »
Hey Bruce!

I have (Knocked down to component level) a 20mm thick solid welding surface 6ftx4ft - The reason its knocked down: TOO DAMN HEAVY TO MOVE!!

What I eventually settled on for minor mobility and stiffness (Price too) was a 6x4ft piece of checker plate - 1/4" thick...

4x Pipe legs at the corner, a 6" vice strategically welded into place, and, as a stiffener, 1x125mm wide galvanized lip channel welded underneath down the center of its length - the required braces are on the legs, the stiffener makes it more than adequate... As a bonus, the lip channel makes a handy clamp point for the earth leads....

Obviously, the rough side of the checker/tread plate is not the top of the bench!

With a decent run up and a sore shoulder later, I can move the thing a few inches at a time!!

Hi Mike & Dax...

I've had a smallish lathe for many, many years, and a few biggies too over the time... Unfortunately, all the work I have done with them have been pretty much one-offs, nothing wanting cnc type things... but... I might just retrofit one for S&G... If I ever get the time...

On topic...Well... My scatterbrain has enough dealing with keeping organs functioning to worry about staying on track....
Typical - ADHD - Highway to, Oh look, A squirrel....

Yep Dax, Satans' little helpers are at it flat out.... I'm getting tired of 2am patrols around the plot to scare the sh!t out of them... Time to hire a big dog, methinks.... I'm so "over" doing my own barking!!

Keep it spinning....

Oh.... Add Project #3 to the latest list.... My second "little" 3d printer arrived yesterday... Assembled it and tested it out...Very "Cute" ... Creality Ender-2... For tiny stuff....

G'Day Y'all....

Despite a long absence from posting, I haven't written myself off, lost any limbs or even more than the usual number of weekly (weakly) brain cells.... That I am aware of anyway... (Kinda reminds me of a saying I heard some time back.... Being dead doesn't bother you, it bothers those around you....Same as stupid..... Well, not being dead means I probably belong to the latter group, I suppose...)

I have had tele lines stolen twice, extended periods between replacements, and, as such, have been a bit out of the "loop" to put it mildly.... What this has done has allowed me, or rather forced me, to go and do something different for a while... Well, so i did!!

In the last 4 months or so, I re-learnt 3d Cad (Damn.... Things have changed a bit since I last used it 20 years ago...) I have gotten myself into a bit of "Freecad" to support a couple of pet projects that I have had on the bucket list for, well, eternity it seems...

Project#1: 3d Printing - Got myself set up in a tiny way with a nice little Creality dual spool printer - Looking at making replacement grips and plastic bits for the "older" firearm restorations that are all but impossible to come by parts-wise these days, as well as maybe a bit of burnout casting in bronze/brass/ali for parts that need to be molded, and, well, maybe a few toys too!

Project#2: 3d Router - Managed to to pick up an Ahdunno based self-assembly-crappy-chinesium router that has a shit-fit when it sees anything more than a point buggerall cut in soft balsa wood... but this is more of a "school-fees learning tool" - What I re-learn here, I will scale up for my somewhat larger 4000kg Kondia mill to do some real interesting stuff... This should be entertaining!!

But, as usual, I am about as far south of Lister territory that I could possibly be!!

Anything happened of interest in the interim 4 month's I've been away?

I am now on a Celcomms based internet, that costs the earth, barely holds together, and.... well... still no tele lines that I am willing to trust yet! (So browsing the internet and boards takes way more time than what I have patience and funds for, please bear with me!!)

Keep it spinning....

Cheers
Ed

Yep....Unlikely to be going down the center of the element then... Fuel could seep past the outside and down past the plunger possibly....

Looking at the basic layout, (don't have schematics, so might be way off track) I am more prone towards the leak coming from the bottom of the injector pump and making its way into the crankcase... Just my (less than) .000005c worth....

I jump in to add my not even 1c worth....

<Quote:>
With respect to your idea of water injection, I doubt that this will do anything. In an ICE the water droplets work under high pressure on each compression stroke, this has a hydraulic/steam cleaning effect that you will not find in an low pressure burner system but I might be wrong and look forward to hearing what you discover.
<Unquote>

I have been playing around a little with this lately and found one interesting thing, haven't verified or documented it properly yet, but when I took the water from the over pressure bleed off/expansion valve of my boiler to the path of the flame, the stack cooled slightly overall, but I found the heat transfer to the heatex coil a little better... Could have been atmospherics, dumb luck, or error... As I say, I need to look into this a bit more, it could prove interesting....
