Why can't I J-B Weld together a receiver?

That might be an interesting experiment with one of those laser cut U bend em flats .

I'd be worried about the stuff cracking when that carrier starts slamming...???

I've seen JB weld not work in good conditions and fail in good conditions.
It might be a good emergency fix in some cases, but I wouldn't trust it for anything.

I have used JB Weld to make repairs to US Naval steam system components. This is an authorized material and it worked great. But it was always used to fill voids and cracks as seen in flat gasket surfaces, never as an adhesive to join two pieces together. It was never used whenever there was extreme stress placed directly on the JB Weld. If you used it to put an AK together, I doubt you would get 100 rounds through it before have a disassembled kit on you hands.

Sure would be cool to see though.

1. The top rails are not under 'extreme stress' , the are subject to abrasive wear do to the carrier riding on them.I am willing to bet the Laser Cut Flats with just the bent tabs and no JB weld would last over 100rds.
2.The JB weld would be more of a filler than an adhesive.
3. The middle of the LCF would bear the brunt of the stress (extreme stresses??) and it would be solidly riveted/screwed/welded into the front and rear trunions.
4. The bottom of the LCF would , I think bear the brunt of the stress and if it is clamped (which it is between the rear stock and front hand guard) and JB welded , I think it would stay put reasonably well.
Granted this would not be the preferred way of assembling a receiver , but I DO think that it would work and that the assembled rifle would stay together for much more than 100 rds.

Taking your life in your own hands if you try that. I'v welded receivers by mig welding, only to see them fail. If mig can't handle the stress, JB sure as hell can't. The manufacturer of the lazer cut flats recommends only TIG welding.

40-60 rounds I think is what I said. You cant let JB get hot. Itll melt to just the way it was when you first made it up. A guy I know tried to fix a cracked exhaust manifold with the stuff. 15 seconds tops and it was blown. There is just too many extreme forces going on in a rifle such as an AK for "glue" to hold it together. Heat, expansion-contraction, oils and solvents, recoil, shock in the action etc. JB is good for alot of stuff. I always keep it in the shop. But guns and JB should not be spoken in the same sentence.
