JB weld's info
Properties (psi)
Tensile Strength: 3960
Adhesion: 1800
Flex Strength: 7320
Tensile Lap Shear: 1040
Shrinkage: 0.0%
Resistant to: 500 F


Devcon 10110 info
Compound has an adhesive tensile shear strength of 2,800 psi and a Hardness 85 Shore D


So, JB claims ZERO shrinkage, which is impossible, but for the layman close enough. The devcon has a higher shear, and not seen is Devcon steel is also harder than JB.Devcon has a slightly better shrinkage number, but I don't have the info to post.


Is JB probably plenty good, I'd say yes, and chemically it is good for all gun solvents sans MEK, which both will be softened by.

BTW, epoxy is not all the same, many are terrible for gun applications, usually either too soft or too hard, and shrinkage is Brownells advertising method of suggesting their bedding compound is the best....and there are many poor epoxies for bedding a rifle.



I think Va'S gun will never know the difference.

Da chit works.

Gotta couple/three more that need doing soon, too. The Mannlicher CZ550 is going to be interesting, to say the least.

A bit OT, but what's with the price of epoxy in recent times? Seems like it is skyrocketing. A basic Acraglas kit is pushing toward $30, and a Glasbed kit is $32.

Seems to me that it's been going up much more than general inflation, and has been for some time.

I use Devcon steel putty these days but used J-B Weld a few times. It worked well and those bedding jobs are still holding up nicely. The guy who taught me about bedding will only use J-B Weld and he successfully beds lots of rifles for lots of folks.
