The MG2 and the aluminum welding rod seems to work well with pure aluminum alloy, I'll be looking into all the various torch welding rods out there for differing alloys.
There is a vent and there old are seals that leak, many of which I will replace. I did some YouTube research, I'll probably grind down the "aluminum solder" blob and see if it holds then clean it with a solvent, coat it with some JB Weld and let it cure for 24 hours... just to make sure it doesn't leak. I'm not planning on keeping this car too much longer altho I've been saying that for about 10 years lol. I did see a YouTube where a guy repairs a worst crack on a transaxle with "industrial" JB Weld.
You may have a point there! I've got a scrap piece of Aluminum rear end to a lawn tractor that I test welded and it seemed like an easier bond than when I did the transaxle... altho I might have gotten a decent bond but I'd better do some research before ;putting the gear lube in... maybe I can put some compressed air in there to see if there are leaks at the repair...
thanx for the heads up!
Posted a short vid on StockTwits and YouTube, nothing too special although I am using oxy/MG2 to weld aluminum, something I've never done before. Have yet to test the repair but I'm waiting on some parts to put it back together and then I have to re-install and my wrist is still healing (but healing relatively quickly- I'm eating lots of Kale these days)
Welding aluminum is actually pretty cool, I'll have to look more into it, I'm using cheap fluxless aluminum welding rods that I got from Harbor Freight. There are probably other welding rods to try as well. I tried using a mini-Butane torch and a propane torch but found that oxy/MG2 worked best when working on my scrap aluminum test piece.
actually, that rumor would not completely surprise me lol.
Except I thought his rockets were battery powered.
With distribution growing people can more easily try mg2 and see how awesome it is for themselves. Open the valves ad spark the torch.
