Today, I started to address a problem with the filtration system I added to my parts cleaner almost two years ago (see
Post #209 earlier in this thread). I was skeptical from day one that the bulkhead fittings would be leak-free, and that skepticism didn't take long to prove correct. Those bulkhead fittings don't seal the threads, so solvent follows the threads and slowly leaks out. It's pretty slow, but annoying. I've had a pile of oil-dry under the tank since shortly after I made Post #209. A few weeks ago, I decided to fix it by welding some steel couplers to the well of the tank.
However, the holes I cut in the tank were larger than the O.D. of the couplers I found. In order to weld them in with any hope that they'll not leak, I need to build up the O.D. before welding them to the tank. Inspired by
@NashvilleTJ's control arm welding technique, I decided to use the same technique to build up a weld on the couplers. Instead of using zip-ties and a jack stand to hold the MIG torch, I figured the Chinese must have made a torch holder and put it on Amazon, and I was correct. They did, and I jumped right in and supported those communists (again) by buying it. I also bought some Chinese bearings to make the jigs, a Chinese foot switch, and a Chinese copy of the Amp connector needed to connect the switch to my Millermatic machine. Why can't more 'mercans put stuff on Amazon???? I'd rather support them, but there were no options!
Anyway, after getting over my guilt, this evening, I took a piece of aluminum angle that I (not kidding) found on the dirt road to the homestead and mounted the bearings to it. Then, I set it all up on the welding table:
And that's as far as I got today. Stay tuned for the exciting conclusion...
