Bedding compound on light weight stocks

Has anyone had any experience with using Devcon, or any of the Brownells products in a light weight stock? I just received my Lone Wolf Summit XL, and while relieving it, I started to wonder if the Devcon would be the best compound what with the foam core.
The Devcon works a treat with wood stocks, but does it have enough strength with a softer foam around it?
Thanks for the assistance.
 
Where were you relieving it? I think once you hit the foam core you may have gone too far and may have to use fiberglass. I've never worked on this stock but the foam cored ones I have used I never broke through to the core. Hopefully someone who has worked on Lone wolf stocks will be of more help. Devcon steel is one of the strongest epoxy bedding compounds out there but it needs to grab onto something solid to provide a rigid bedding surface.

U answered your own question..Devcon is strong but what might be around it might be weak...if while relieving the stock and you hit the foam just continue on. Then get some fibreglass resin (ONLY) mix up a little and pour it in to the relieved areas.No more then a teaspoon or so. Swish it around and let it soak in and cure. Then do this again if needed and then use the devcon to do the final bedding. Now you have a strong base and something for the devcon to take to...

Its a very light stock, 12 oz, and there was only a VERY thin layer of resin on the back side of the relieve for the recoil lug. The stock came very close to fitting well with the inletting LW did on it, but it was about 1/8" too far forward, so I had to relieve the back of the recoil lug inlet, as well as just to get some space to put bedding compoud in to.
On the "heavier" composite stocks, I don't think its an issue.
Icehunter, thanks for that suggestion. The FGlass resin won't eat out the foam? I wonder if would be worth bedding with Kevlar fibers mixed in with the Devcon, or even bedding with Kevlar fibers with Fiberglass resin?? I imagine the FGlass resin would be too brittle for effective bedding?
I just realized that asking if the resin would eat the foam was kind of stupid, considering its Kevlar/Carbon layup on foam.
Not to try and re-invent the wheel or anything, but I wonder if this http://solutions.3m.com/wps/portal/3M/en_US/3M-Industrial/Adhesives/Product/Catalog/Detail/?PC_7_RJH9U5230GJJ60IS8FSO6Q3GD3_nid=WXJ20HH599be7ZMZSJBQRHgl would be any good as a bedding compound?
There are so many other adhesives out there besides Devcon and the Brownells products that most people just don't ever get exposed to.
The DP420 is used in building (among other things) Carbon fiber bicycle, and bonding Carbon tubes to ferrous and non ferrous parts. In that application, the adhesive has to withstand repeated dynamic loading and impacts, both shear and tensile. This stuff is NOT brittle at all. And, I happen to have a bunch of it from some other projects.

Devcon is very strong but cannot just bear on the foam. You need to make sure the skin is taking the load.

As for using resin to bed, the reason certain materials are used for bedding is that they have minimum shrinkage when they cure. Devcon is excellent. I like the F Aluminum putty.

I would still just use some fibreglass resin to make a so called root and bed from there. The resin will soak through the pores in the stock and give it some strength...then bed it from there. The reason for proper bedding compound as noted above is shrinkage and other factors.Use the proper materials,do it once and you are done...I just got done redoing a .22 that had automotive bondo as a front bedding material.

Looked like hell and after grinding it all out and doing a proper bedding job on it she drives tacks now..any thing can be used but that is the difference between a proper job and just a #### job..
 
There used to be a product called duramix sold for bodywork that is the same composite as the stock, it permanently melds into the material of the stock.
The stuff is still made but 3M took over the company that made it, haven't bought any since 3M did the takeover but i know it is still available.
 
Do not use polyester base resin on the foam, it will eat it and is very brittle, any epoxy will work well. Try to get one with longer curring time. I by my epoxy from boat supplier, (WEST SYSTEM 105) also you can get different fillers that you can mix with epoxy to make a very strong.

Where can you find duramix at yet?? The backer setting stuff is incredible for fixing things...and after it hardens its like a rock. Wouldnt use it on firearms but I used up the last we had last week fixing one of my helicopter bodies...
 
There is a auto supply store in town that stocks it under the 3M line now. I have used this stuff on a few flimsy stevens stocks, install metal rods and bed with duramix and you have a stock better than most custom stocks.

I am going to have to check that out on monday with our suppliers...does it still go by Duramix or has 3m changed the name of it to something different?? An if so do you know the name of it??

Nice try.

What's with the comment, obviously you must have done things exactly like what i did and know everything.:rolleyes:

As far as aesthetics no it doesn't change the look of the stock, BUT after holding a boyds stock last week i can guarantee that the modified factory stock feels stiffer and stronger than the boyds.

Try first to saturate the foam with thined fibreglass then wait till it will sets up properly, then use the aluminum (light) Devcon, rather expensive (about $4 per oz) but very best for the job. Don't use Brownells....it is not only substandard to Devcon but also ($14 per 1oz or so) big ripoff. What would be so expensive in that kit?...wooden spatula and paper mixing cup?
 
After much research and phone calls to adhesive suppliers, I'm pretty sure I'm going to use the 3M DP 420. The one thing it has going for it is its impact resistance. Devcon does not have that, as it is rather brittle.
The 3M should be here tomorrow, and I can start on the bedding. I don't see any problem using this product, only benefits. I'll let you know how it turns out.
