Marine Tex-Devcon??

[nmkid]

Which product would you like the most for skim bedding aluminum block? I see the Marine Tex comes in a 2 oz. kit. Is that enough to bed a rifle? Thanks

No Devcon is best product out there. At least that's opinion of the guys that really know

There is a recent article from "Speedy" in the Bulletin section.

marine tex is supposed to shrink less, I doubt it may make a difference though if the action is also using screws.
I'm sure .003 could be taken up by tightening the screws up a tad.

That would depend upon where the shrinkage occurs.

 

[GerryM]

I don't quite understand what your getting at?
If it shrinks from the surface of the wood or metal it's pro abely due from poor prep.
If it shrinks uniformly like it should { devcon etc it shouldn't matter, as I said you more then likely will even notice the shrinkage.
If the action seems a tad loose in the stock i would tighten down the screws.
Now it may make a differance in a glue in bedding job.
I think thats what speedy was trying to get too.

J-B weld works also.

A couple of things come to mind. I read the wright up on Speedy's test using a 1.000" square of epoxy measured after a year. The claim was that it shrank 3-6%. That's .030-.060" of an inch and way, way above the claims made by Devcon, for one. I wonder if that was a typo by someone. Nevertheless, given ample cure time between the bedding where there may be some substantial thickness of bedding material, and the final coat, which may be only a skim coat, the amount of shrinkage becomes much less. IOW, we don't typically bed an inch deep. I do like a uniform depth of the bedding and typically machine out the bedding area in a mill for this reason, prior to bedding. FWIW, I like Devcon and Marine Tex both, as both have given good results for me. The technical data sheet for devcon states .0006" shrinkage per inch, cured. That's not 3-6% shrinkage...it's .06%. Take the fact that even a heavy bedding coat is around .100 thick, you can divide the .0006 by 10, due to the bedding being 1/10th of an inch thick and you get .00006"..That's 6/100,000 of and inch over a more practical bedding thickness. Unless there was a typo or mis quote in the article, Devcon has completely mis stated it's product in its TDS...by a large margin. To me, being a dumb old hillbilly from Ky., 6/100,000 is close enough. Someone please tell me that they machine to those tolerances daily, in their basement.

So...The Marine -Tex comes in a 2 oz. kit. Is this more than enough to do a skim bed??

I've never bought in that small of a quantity. I measure on a scale, typically, when mixing. From this, I surmise that 2oz would be just about the right amount to bed an action. So Yes, IMO it is enough.

Two ounce Marine Tex will do two actions if you are not wasteful but if it's your first time it's probably good for one job and any touch up needed.

 

[Dusty Stevens]

Youd think with all this horrible shrinkage all those actions glued in with jb weld and 5lb 22" barrels prying on em for 20yrs would just fall out on the ground

 

[6xcshooter]

it don't shrink enough to make a rat's ass difference

You can get small tubes of devcon on Amazon
