Propane CS clone power loss, welder fixed it.
« on: June 15, 2019, 11:17:21 PM »
My neighbor Jeff is the owner of the Propane modified CS from DES. He's been running it for the last 4 years with no troubles.  He mentioned he was having reduced power- couldn't carry both well and washer at the same time.  I suggested he check valve timing, as we had twiddled those to reduce exhaust/intake overlap to reduce propane smell in the engine room.  He did, and found that our extended push rod for the intake had failed. We had added 0.5 inches of aluminum spacer under the cylinder to reduce compression, so the longer exhaust rod worked fine for intake but former short exhaust needed a couple inches added. I had done weld bond kludge with some bits I had on hand; epoxied carbon fiber tube and added rounded end bit.  It had failed after 4.5 years, the carbon tube was now cracked as the ends pushed together, reducing the intake opening to only 4 mm from a normal 8mm.

I was thrilled to have a small welding project.  I had some rod of about the right diameter and welded on a new extension to the push rod. I used 7018 for the job, with some 6013 for finish filler.  It is very satisfying to have my new 24V battery welder put to good use, again. We installed it and reset the intake opening per the IO flywheel mark we put on (using 38AC's brilliant method), and now she's back to full power again.

Problem.  Investigation.  Diagnosis.  Solution.  Repair.  Result!

So satisfying when it goes like that.  Well done

I'm very keen on welding projects these days. :)   Thanks MikeNash. 

I'm going to look for a shade 8 lens- I still can't see very well through my shade 9 lens when a cloud rolled over.  Shade 6 is too light, so I'm closing in.  (Too much and too little are my specialties.) Being able to see the work is a BIG advantage.

As I have gotten older (62) and my eyesight has gotten crap (gone from occasional use of reading glasses ten years ago to prescription lenses and the beginnings of cataracts in my "good" eye) I have done a couple of things

One:  I use a diopter insert - just a magnifying piece of plastic that slips into holders in your helmet.  Might be worth a try?

Two:  More importantly - I make sure there is good bright light shining on whatever I want to weld.  Not necessarily sunlight, as being "out in the sun" or looking towards the sun can confuse the auto-darkening thingie, but just good artificial illumination

FWIW I have found this makes a difference

Cheers

Got your welder set up just in time Bruce.
Nothing so satisfying as just having the tool on hand to effect a repair to help someone out.

I found a MIG/ TIG/ Stick welder I am going to buy when I get back. On special, $200 off and a known brand so looking good.  Comes with a decent auto darkening helmet so will be good to have one of those too. I just made a space on the pegboard in the shed for all my welding helmets, not sure how I aquired so many but I'll see if I can find somone that needs a spare when I get the other.
Got the seal of approval from the Mrs to boot for the new toy. Was even asked why not go get it today?  Will be nice to weld with a machine that works smoothly unlike the one I have and to see what modern stick welders can do.
Guy in the tool shop was talking about all these features I never heard of.

In reality it Boils down to things to help the totally inept with no idea to be able to stick a couple of bits of metal together.
Much to my surprise, some of the much bigger serious machines had the same " Driver aids" and even more!  A touch screen on a welder for the automatic settings?? Really??

I mentioned a Current  TV ad here were a 4WD  ute parks itself completely hands free. I said to the guy Just as you shouldn't be driving something that size if you can't park it, you shouldn't be using a welder if you need it to do these basic things for you.

Hey Glort, could you please let us know what it is you are buying and how you get on with using it. I was trained as a welder back in the days before MIG welders became popular.  Back then stick welders and TIG welders were separate machines. I remember having to learn oxy/acetylene welding of aluminium. When I see all these new idiot proof machines I wonder why I bothered to learn those skills. I guess it makes it much cheaper to train people these days but I doubt that it makes them better engineers.

Hi Bob,

This is the unit I have in mind:

https://www.totaltools.com.au/featured/185a-multi-process-inverter-welder

Seems a good price as all I can find on fleabay for the same unit is about $200 more.  I'm not sure I'll ever use the TIG feature, gas still seems overly expensive even with the buy your own Bottles. Then again, do you REALLY need gas?  I used to gas weld a lot and use wire coathangers for rod. Don't say they were the strongest welds out there but they never broke on anything I stitched up so was good enough for me.

As I see it TIG is like electric Gas so I wonder if standard stick rods with teh flux wouldn't give a decent Weld.  Again, not talking High pressure pipe or extreme load bearing here, more thinking lighter stuff that gets tricky with MIG but TIG seems OK with.

I wonder how a TIG gun would go with DC?  Few solar panels in series / parallel would throw a powerful arc.

Will CO2 do TIG or  does one need argon? Only thing I can thing of for making CO2 is Baking soda and Vinegar.

If I find myself doing enough welding, I might pursue to a MIG conversion via replacement parts, but for now I'll manage with my simple fixed voltage stick welder. Builds character(?!) I'll bet Glort's new inverter welder will be a dream boat to weld in comparison.

I wear my "arms length work" glasses for welding. I'm nearsighted with presbyopia. I have glasses for every working distance, as I found bifocals impossible and variable lenses a headache (literally).  With some study and my own trial lens/frame set it was easy to get just the right lens RX. ZenniOptical is marvelously inexpensive.

I still have some range of focus for my eyes, and MS affects my ability to scan and focus rapidly but I have way less headaches when I can put my work in the middle of that focus range.  Avoiding overcorrection strain is especially helpful, undercorrection is much less of a problem, I've found. "Soft focus" beats a headache by a mile.

There was a brilliant bit of research done by a Australian eye doctor.  He found that if kids were given bifocals with plane glass for distance or close, depending on whether they are nearsighted or farsighted, their vision didn't deteriorate rapidly, requiring new lenses every year, stronger and stronger.  He proved this in fairly large trials of school kids. So while good for their profits, the current practice of optometry is adversely affecting kids vision health, and costing parents a fortune. I've found that almost every field of medicine is like this- profitable procedures are supported and protected first and foremost, public health be damned.

Bruce, I have not read all the postings about your welder but if you are using an old school shaded lenses helmet and having issues you might want to consider an auto darkening unit. I had all but given up weldng due to not being able to see what I was doing no matter the shade. I think it is due to many hours under a hood and multiple seriois flash burns. I had avoided the automatic helmets due to lag time and flash but that is all fixed now in all but the cheapest of cheap helmets. I bought a middle of the line cost wise Hobart and I can once again, see what I am doing and welding nicely once more. I can't get rid of my tipping the helmet habit to the amusement of my sons who have never used anything else.

Thanks 38ac.  Yes, I tried the auto darkening units. I can see how for neurologically healthy folks they would be great- you can dial in just the level you want for the dark level.  I bought one helmet and also one of the auto-darkening lenses.

Alas, They all seem to use a microcontroller chip and the accidental radiated emissions from clocked digital circuits with unshielded wiring affects me enough that I'd have to redesign the electronics myself to use analog components.  I looked at that, took an $11 active filter type unit apart and tested the LCD and mini PV panel. I could make up my own circuitry to control the panel without a microprocessor.  I may do it yet, if I can't get a passive filter that is acceptable.

Hi Glort, that looks like an absolute steal at that price. I shall be ordering one next week. I have used CIG welders before and found them to be reliable and they have a nationwide parts and service network.

My only concern is that this does not have the option of a foot pedal for welding highly conductive materials like copper, brass and aluminium. These metals are so heat conductive that once a puddle of molten metal has been achieved it is necessary to reduce the welding current or the weld will grow to twice the expected width. I suspect that it would be easy to bypass the current controller on the front of the welder and connect a foot pedal.

My other concern is that it does not say if this is an AC or DC welder. For aluminium welding AC is a lot better while for a lot of steel welding processes DC is better. This is because of the magnetic properties of molten steel when exposed to high electrical currents, even the polarity of DC can make a difference in some circumstances.

Let me know how you get on.

Hi Bob,

I asked about the pedal and the bloke I spoke to said they pretty much aren't used any more.  I have heard this before but not sure why.
Maybe electronics takes over, dunno how.

Far as I knew the polarity had to be reversed for gas and gasless wire but I don't know about Ac and DC. Thought they were all DC but I have only used simple old machines.
The guy that works for my faher was a gun welder years ago till he decided to give it away and ai have seen what he does which is impressive. I was going to show him the machine tomorrow and see what he thinks.

Won't be getting mine till I get back which has to be before the end of the month but I'll let you know what the other guy says.

This surprises me not one bit and in fact confirms what I have thought from experience.
The glasses I have for close up are very low power. That said, I notice, If I wear them for long periods, my eyes are worse without them when I take them off than if I didn't wear them at all. 
I have noticed this since I started wearing them.

There is also the very noticeable " Push " by the optical industry to get new glasses every year.  I had my eyes tested a couple of months ago. Did the test, take you out to the shop to select new glasses.... at great cost even with a health fund.....
Clearly weren't prepared for me to ask what the prescription was and didn't like telling me.
They said we will give you a print out.  I stood there waiting and was told we'll pick your glasses and print it out for you. I said would you please print it out now.

Oh, gee wizz, hasn't changed since last year, WTF I want new ones for if my eyesight hasn't changed?
Ummmmm. Next came the baffle them with BS sales pitch.  I looked at my wife, she held her head and said Oh no.....
I then fired a bunch of technical questions back that had their heads spinning . Don't try and baffle a photographer with BS about optics and worse still, Don't try and sell a salesman.

I did want new Sunglasses  with a VERY small ( smallest) correction . Daughter picked them up some weeks later and I put them on and nearly fell over.  They were miles too strong.  The ground looks like it was at chest high and my legs looked 6" long. 
Took them back and they told me they were correct. I asked for who.  Re tested, put on the test glasses, walked outside, still too strong.  Optometrist said can't go much lower. I said give me lowest correction. PERFECT.
Get them back, NOT what I asked for.  It's over an hour back there and they are going to know it when I go back again.

Next year, If I think I need them, I'll have a test to check and then any glasses I will buy online.  I know a couple of people that do that including my dentist and he says He orders 10 pair cause he is always putting them down somewhere and he has never had a problem, unlike similar experiences with optometrists like mine.

I definitely agree that prolonged wearing of spectacles causes weakening of the eye muscles causing further deterioration. I try to wear mine as little as possible. One thing I did find that helped a lot was bifocal safety glasses, these are cheap disposable plastic glasses that have a magnifying lens in the bottom, those lenses comes in different strengths. I can wear them all day without a problem and they only cost a few bucks a pair.

I got interested in optometry because of headaches and frustrations with the optometry shop making lenses that I didn't like. A friend had found that intentionally reducing the RX worked wonders so I thought I'd try.  I found a training manual on how to do eye exams for missionaries and studied it.  I bought a big trial lens set for about $200. I also bought some plastic trial lens glasses, a set with a range of pupilary distances, mine is 65mm.  So I get to try the actual prescription in a range of situations and lighting before I order.

The Rx I made for computer use has my eyes about 4 feet from the big rear projection screen.  I found that while I had "soft focus" at a distance, I was still barely legal for driving with them, and had much less headaches.  My vision improved about a diopter, and now that same RX is my "distance" lens, with about 20/25 vision at 20 feet and I still can use them for the computer. 

My regular glasses are a $6.95 frame with mid index plastic lenses with an additional $5 for antireflective coating.  Shipping is $5 no matter how many glasses.  I just ordered some spares as I don't like looking through scratches and recently rolled over and wrecked my glasses on the sofa.  I got 2 distance and 2- 80% amber sunglasses (a $6.95 aviator style plastic frame).  The whole bill including shipping for 4 (!)  sets of glasses was $62.54. PM me and I'll send you the invoice if you don't believe me.  I get the glasses by mail in 10-14 days.

The other upside is that I have been able to help some low income disabled folks get new glasses, including bifocals or variable lens, and prescription sun glasses, that they could otherwise not afford.  It saves time to start with their old Rx, but I can do it from scratch, also.  Half a dozen are so chemically sensitive that they can't go in the optometry shop, and are largely home bound.  It's nice to be useful.
