Default Old School homemade welder build

Here is a portable welder I am currently building, has a WW2 24volt 200 amp aircraft generator and a 1971 Datsun A12 70HP engine as the drive unit.

Part of my flywheel adapter, cut it out free hand with the plasma cutter, drilled the bolt holes and the center hole for a 1 inch stub shaft for my pulley to go on.




Here is a more recent photo, have moved the generator inboard so it will be a more compact unit and look nicer, so will cut the small outer frame off, flywheel adapter is just mocked up for now, has not been bolted to the flywheel nor had the stub shaft welded to it.

Looks nice. Will you need to have your freehand cut adapter balanced? A little bit of balance weight makes a lot of difference on a rotating tire/wheel!

Had my cousin true it up on his Metal Lathe. He is amazing, he is 75, came from Slovenia when he was 25. He is my late great grandfathers nephew. He started learning his machinist trade when he was 14, he was sent away to a work school as was the common practice when Slovenia was under communist rule back then, he escaped like his Uncle before him and came to Canada. The aircraft generator was origionally my cousinis, he used to drive it with an old Wisconsin V4 and that was his portable welder.

I made one of these aircraft generator welders back in the seventys. The one I had was rated for 400 amps and I powered it with a Volvo engine with two carbs. I put on a belt driven governor to control the speed.
It worked for a while until I decided to use it with an arc-air. That was more than the generator could handle and it went up in smoke.
The Volvo went on to power a log splitter for years.

My dad and his brothers powered one of those generators by belting it to the A John Deere for welding. Dad said that under a good load, that JD was jumping in its tracks!

Vintage2strokesmoke: Nice looking build there.

MoRo: I'll bet that was probably the Coolest Sounding Welder around !

We had a welder rigged up like that years ago and it welded good. Is there any chance of getting electrocuted with it? I worried about that.

I do not see why it would be any different from an actual factory built unit as for the safety aspect. I do have 2 of the generators....identical 200 amp models, any one know how to run them in Paralell properly? As near as I can tell is to connect the power wires together then connect the field wires together aswell. I looked online but could not find a definite answer.

Nice looking build. I find projects like yours very interesting. My granddad had a welder that run with a model a engine. Then for some reason he put a 4 cylinder wisconsin on it. It never worked as well.

My old Hobart Welder originally had a Straight 8 Buick on it, but it too got changed over to a Wisconsin V4 shortly before I bought it.

Here is a site that describes how to build an arc welder (including an arc stabilizer and rheostat control) from an aircraft generator - http://www.metalwebnews.com/informat...arc-welder.pdf

To ensure constant/consistence welding capbility, an engine governor or an electrical solenoid controlling the engine throttle may be needed.

I wish I did, but I was only told about it at the auction where I bought the welder. It had already been changed over prior to that. The V4 was totally rebuilt, but he got the valve guides a little too snug and the first time I ran it, when I shut it down the valves siezed up in it requiring a little work on my part before I could use it again. They're still a bit sticky, so I may need to ream the guides out a hair more yet.

I don't remember why he said he changed it over, whether the Ol' Buick got tired or someone made him an offer he couldn't refuse to buy it from him or if he just had the Wisconsin laying around and decided to put it to use. It's been 15-20 years since I bought it, and I don't remember the guys name anymore to go ask him again.... If he's even around anymore.

Ya have seen that site, and will be using a solenoit for the throttle too. Great minds think alike lol

Here is the flange mounted to the flywheel, put my shaft through the 2 pieces to center it, then tacked them together. I then drilled my holes into the flywheel, removed the flange and tapped the wholes, just have to weld the shaft to the flange now.

Cut the holes for my instruments, mounted them, and also cut the piece of frame off the bottom that went out to the side where I was origionally going to mount my generator unit.

Worked on my fuel tank the other day, shortened an air compressos tank, cut off all the brackets, put a filler neck in, and made mounts.
