Modifying the Pistol Grip on a Fiberglass/Synthetic Stock

[shotgunshooter3]

If one had a fiberglass stock, such as a HS Precision, with a traditional sporter profile, and desired to add material to the pistol grip area in a way durable enough to withstand the elements, how might one go about doing that? Materials used, method, etc.

I would assume a mockup could be done with filler and duct tape to make sure it even felt good at all, but for something more permanent (or at least weather resistant to not come apart in snow, rain, etc), how would you approach that short of just getting a new stock?

Wonder if 2 part epoxy putty would do? It's what I built up the pistol grip on my wooden 788 stock.

One would use…..fiberglass.

Easy but yucky to work with. You’d need to slightly grind away the surface of the stock. The Tubes Of You likely have more info than you could digest on fiberglass work.

One thing I know for fact about fiberglass resin: if the mix calls for X drops of hardener, doubling that isn't twice as good. But it is 20 times hotter and the cup you are mixing it in will melt and start smoking.

The epoxy putty may be ok for building, depending on how thick you made it. I’d still slap a coat of glass over it.

Of course….. and far be it from me to discourage shenanigans, but you may take the price of a new stock that you prefer , and subtract the money you could get from selling your stock, and the price of fiberglass and supplies.
The math may not math.

Glass over putty is probably better.

This has crossed my mind. This is to make the grip on my 700 HS Precision stock more vertical, but if I can get the gun to shoot it might just be better to replace the stock or go the duct tape route for a season.

Oh, sit tight. I’ll share with the class.

If the current stock isn’t to your liking is there a ready made stock you do like? What does it run? Could you sell the old stock to defray some of the cost? If custom is where your at, then get to laying fiber glass on that sucker, then repaint. If you can get what you want in a commercial job I’d probably go that route.

So.
Go buy this.

You put it into warm water and it melts together and you can form whatever shape you want and it gets pretty damn hard. So you could use it for testing purposes with zero harm to the stock

Its very cool. If you have kids, its a must. Gives the little crumb snatchers something to do. And if you are a full grown child, it gives you something to do. The real neat thing is that if you mess up, you just drop it back in the water and start over. If I recall its just needs something around 150 degrees to melt .

[shotgunshooter3]

Bingo. That is just fantastic. Thanks!

the ad says you can use a heat gun also. Id do the water to get it hot and melty, get it most of the way. Then heat gun for small adjustments if needed. Or hair dryer. I bet you could foul up quick fast in a hurry with a heat gun.

I use that insta-morph (poly-morph is another brand of the same stuff) all the damn time.

Especially used it a lot when I was traveling for work. I kept a thin sheet of it that I made in my wallet. If I needed something while I was on the road, I would heat up some water (coffee maker in the hotel room or steam iron would work) and I’d just… make it.

Things I made- a wedge to hold a door open, a hook to grab a cable that fell behind the dresser, reinforced a charging cable that was shorting out, a wedge to keep the tray table from rattling on the airline seat in front of me, a shim for a table leg, phone/ iPad stand, etc, etc….

Is talk to a boat repair shop or auto body shop. The best way would be to overbuild the area with multiple layers of “cloth” and resin, then sand to the desired size and shape.

Honestly unless you just like monkeying around with it, you aren’t going to save any money by building up the existing stock. It’s gonna take multiple tries and will still wind up looking like poop.

Have you done one? Or seen anyone else do what he’s talking about? Curious as to how you know what it will look like.

If you go the fiberglass route, take a look at you local auto parts store.
They should sell a fiberglass body repair kit.
CPJ is right about the amount of catalyst you add, I was doing a repair one winter and someone told us it was too cold and the patch would never cure. After we were done we added enough catalyst to the leftover resin so it actually began smoking and cracking as it set up.

[fisheadgib]

The only thing I'll add is that if you choose to use the thermoplastic and then cover it with a layer of fiberglass to make it more permanent, I suggest using epoxy resin. The stock could be polyester, an epoxy and polyester blend, or epoxy resin. Polyester only bonds to polyester where epoxy will bond to any of it.

I haven’t done epoxy work on a stock but have done a lot of epoxy repair in the construction industry. It is a trade and art that you have to do every day. There is no fixing a screw up, it’s tear it out and start over.
