JB Weld is apparently good stuff and if you are a DIY Nerd like me you might find this interesting. | ||

Go ahead punk, make my day |
I had a friend JB Weld an oil pan on a Minivan once. It worked for as long as he needed it too. | |||

I've also heard of two-piece oil pans (cracked all the way across) being JB Welded back together. In the '90s I glued a porcelain wall-mount "chair carrier" type commercial toilet back together with the glue which came with a white Knack roof rack (it was intended to cover the bolt-ends). One sniff of the solvents in the glue, and I knew I had the good stuff. One corner of the bolt-on wall carrier mount flange was cracked from a heavy load at the rock club then in business. And these 3.5g flush gravity models were no longer produced due to the Energy Policy Act. Sure enough, the glue worked and the toilet was saved. Wish I knew what glue it was! This wood putty is good stuff. ![]() | |||

I've had sliding interface machine parts made out of JB weld in place of Delrin, it's the real deal. ![]() __________________________________ NRA Benefactor I lost all my weapons in a boating, umm, accident. http://www.aufamily.com/forums/ | |||

If I need to stick parts together, JB weld is my got to. "The people hate the lizards and the lizards rule the people." "Odd," said Arthur, "I thought you said it was a democracy." "I did," said Ford, "it is." "So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?" "It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want." "You mean they actually vote for the lizards." "Oh yes," said Ford with a shrug, "of course." "But," said Arthur, going for the big one again, "why?" "Because if they didn't vote for a lizard, then the wrong lizard might get in." | |||

Bear in mind that there's very little load on an oil pan; so long as the epoxy isn't damaged by the heat and doesn't break down with the oil, it's good. Epoxy is good for a lot of applicants, not good for some, and a failure in some cases. Regarding the video at the start of the thread, yes, one could put just about anything under the head and get the engine to run...but putting the wrong product there doesn't really prove anything, nor will it last, and it doesn't speak to longer term exposure to high temperatures, pressures, etc, or what needs doing when it's time to remove the material and actually fix it properly, assuming it is fixable at that point and not badly warped. Epoxy has it's place; we hold entire aircraft together with it and make aircraft out of it...but it's not for all applications. | |||

Back in the bad old days when I was a Mazda tech, I repaired several drive key slots on 323 crankshafts. The crank bolt would stretch, then the balancer pulley would wiggle, eating the nose up on the crankshaft. Don't know how long it would last, but I never got one back. The repair probably outlived the rest of the car. | |||

This is the really good stuff, aerospace folk really use it, and 2216 comes in a few other variants. Out of date tubes can be had on fleabay, still very usable and much cheaper. https://www.3m.com/3M/en_US/co...10645+8710797&rt=rud | |||

my existence, while grotesque and incomprehensible to you, saves lives |
The primary advantage of JB weld is that it is dimensionally stable while curing (most epoxies shrink). Makes it work well in a variety of applications. ***************************** "I don't own the night, I only operate a small franchise" - Author unknown | |||

Been using JB Weld for years but I have tried a few new but similar glues and they have also worked very well. Maybe they are getting some competition now. .....never marry a woman who is mean to your waitress. | |||

Woke up today.. Great day! |
JB Weld and JB Quick ROCK. I was in the middle of nowhere racing my dirtbike when a rock punched a quarter sized hole in the side case dumping oil everywhere. Layed the bike on it's side and applied two rounds of JB Quick, due to the size of the hole. An hour later I rode out of the desert 50 miles. I was impressed and it saved my ass from a LOT of walking! 3M makes some panel adhesive (sheetmetal) that is pretty much as strong as welding. | |||

Never miss an opportunity to STFU |
In the past, used a lot of JB weld, and similar items. About 2 years ago I started getting a bad reaction when this product contacted my skin. This included swelling in the face, abnormal breathing and general body inflammation. Later, I got the same reaction when spraying epoxy primers, paints, and clear coats (even when wearing a respirator). Just a warning if you use it frequently you may wind up with the same reaction.
