Hello all,

Had what was supposed to be a great day yesterday turn for $hit. I just got my TRG 22's Stocks back from cera-coating and during re-assembly ended up dropping the fore-stock onto my floor and it broke. I take responsibility for being a clumsy f'n retard but I was shocked to say the least when the stock broke in two.The area in question is one of the thin side panels that extend back from the main body and essentially make up the magwell. It completely snapped off the stock.

Sako describes it as a Polyurethane material. I was reccomended JB weld, however when I spoke to them they said that their products would not bond well to this medium. Can anyone speak to this or reccomend something more suitable? Standard 5min epoxy? Scotch Weld?

Any comments,direction, or recomendations on the matter would be greatly appreciated.

Thankyou,
Marcoman.

I've drilled holes to fit dowels for strength and now just need to figure out what bonding agent to use?

Do you have a picture of it? I wouldn't hesitate to ask Sako for a replacement. I have beat mine to heck and it is only scratched up, so maybe it was just defective or you hit it "just right".
 
While that area of the stock is thin, it should not be that prone to breaking. Either there is a void in the polyurethane core material, or the guys applying the cerakote baked it at too high of a temperature. If the former, Sako / Beretta should fix under warranty. If the latter, you'll have to negotiate with the persons who applied the cerakote.

Until you can get a replacement forearm, repairs can be effected the same way repairs are done for boats -- using polyester resin reinforced with fiberglass strips, on top of the polyurethane core. It is recommended that you splint accross the break(s) before applying the resin "repair gel".

I was thinking the same thing. If the cure was at too high of a temp and in turn baked the stock to be brittle.
Could be. The fact that it wasn't bolted to the rifle may have compromised its strength, as well. I've dropped mine off the shooting bench onto concrete a couple times. Never an issue.
 
Do not use FAST curing epoxy. If you desire on epoxy use slow one, complete cure 24h. Devcon is one of the top. If you need some flexibility after cure I would recommend using archery hot glue, it is very stress resistant (it is used for gluing arrow tip to the shaft). Hope this will help. If it is possible, apply the glue on back(non visible) surface.
 
Thankyou for the replies and suggestions. Sorry, its been a long day. I will post pics tomorrow so that it is easier to understand what I'm working with. I have contacted Sako/BerettaUSA and will hear back from them next week.
 
Bump with pics, Which of Devcons epoxies specifically would suit this?

I need to get this right the first time as it will be a mess if the epoxy doesn't bond properly or fails to set. Your suggestions appreciated.
 
For bedding and stock repair I use Aluminum Putty 10610. Because Aluminum filer is light and non corrosive. Replace the drill bits (brittle, the are made from hard but brittle allows, HHS or Carbide) with music wires. You can buy them at your local ACE store in different diameters. They are hard but flexible. Stainless steel dwell pins are also good option, again ACE.
BUT if temperature treatment (duracoating) changed your stock material micro structure you have to replace it. HOPE this is not the case.

I've long had my eye on various TRGs, but this doesn't look good to me. Think about dropping in the field with the weight of the barrel and action, not good IMO. Good luck with repairs and I too would contact Beretta and see if they'll help before I would do anything to it myself.
 
Thanks to all for your suggestions. I have the stock repaired so that it is serviceable until I hear back from BerettaUSA.

Actually turned out pretty good. I will still look to replace it in the future.

Here it is; TRG 22 in Patriot Brown ceracoat, and my TRG 42 factory Desert Tan.

It is difficult to find a polyurethane that will handle very cold or very hot well. We made the gen 1 grip panels for the Whiskey-3 out of polyurethane and there was only 1 compound if I remember that was acceptable but I don't think the heat tolerance was over 200 degrees F. That's one reason our forend is aluminum and not poly like the TRG. Basically that forend shouldn't have been baked as is done during the Cerakote process. Even injection molded components really shouldn't be baked at those temps although they handle it better. Good luck with your rifle but it does not appear that it was a manufacturing error.

seanh;

Will do. I had expressed concerns (heat) to the company that did the ceracoating and they assured me that they would use a very low temp. I'm sure my non coated TRG42 would have probably sustained the same damage in similar circumstances. I think it's just a weak point in these stocks and un-fortunately due to my clumsiness it was exposed.
