Re: Homemade fibreglass stock

It's amazing what you can achieve when you just have a go!I attempted a similar thing a little while ago, i was desperate for a stock that fit me well and looked the goods, problem was i didn't have the cash after buying the rifle so i had a brain wave to modify the HS stock on it.I needed to extended the lop,the pistol grip and add a finger hook(i know what a fu$k#ng brain wave right!).Who did i think i was?I drive a truck for a living!!!Anyway four afternoons in and what a mess!I thought i had bitten off more than i could chew,i got the shits with it all one afternoon and smacked the butt of the stock where i had been working on with a hammer(now i mean i smacked the $u#k of it, all 102kgs of me) in disgust that i had ruined a perfectly good stock and i was gonna be stuck with a barreled action and no money to buy another one, well........ to my astonishment it didn't even chip or crack it ,not even a mark, so i sat down... had a beer and a laugh, looked at the stock and decided that if it survived that beating it was worth trying to finish no matter the result, story is it turned out better than i ever expected and it was hammer proof.Congratulations must go out to you again Kiwi,because i can only imagine what you went through, good on you mate.
Here is a little pic of my brainwave..

Re: Homemade fibreglass stock

300R,

Good Job!!!

It's kind of nice to end up with something that fits you!

Here's one I did. Raised the comb. Lengthened 3 inches. Reformed bottom of but stock to ride the bags. Squared the forearm, added thumb hole and palm swells for both hands.

I used JB Weld, Bondo, quick steel and a piece of pine 2x4.
As soon as your mate posts pics of his molds I make a real one. This one was supposed to be a proto-type anyway.

Somewhere in there is the original Bell & Carlson sporter stock.

Good job all !!!!!

I really like the camo on your rifle Roy.

Nice to see that there are still people that do there own work. (Even when you could buy
something).

It makes the rifle truly a custom.

Re: Homemade fibreglass stock

Here are the pics of the mold as promised.




Sorry I didn't take any pics when I was making them, cameras and gloves covered in resin don't really go together. The funny lumps are used to locate the two halves of the stock correctly. When I make another one I will just use thin rolls of clay to make the locating lugs.

Basically I layed the stock on the bench put clay around it to half way up the sides. Then I put the real estate sign around the stock ( having already cut out the hole for the stock) then fill in gaps with clay. I then filled the barrel channel, action area and floorplate with clay but had them sticking out from the stock to form a lip. Then 4 layers of wax and then hairspray.
Then mix up the resin and hardener and add silica to thicken.Cover the whole stock in this and wait for it to go tacky, it sticks to your glove but pulls away.
You need to put heaps in any corner as the cloth won't stay in tight bends.

Once the resin has gone tacky then coat the whole thing in eigt layers of 6oz cloth. Ideally use 50:50 ratio of cloth to resin by weight. Work the cloth well with a roller or brush ( cut the length of the bristles in half to make the brush stiffer) to get out any air bubbles.

Then walk away for a week.

Now flip it all over remove all the clay and the real eatate sign but leave the stock in the mold. Add more clay in the barrel channel etc and repeat the whole process.

Then cross your fingers and separate the two halvesof the mold, don't use anything metal to do this as it will scratch the mold. I used a plastic fish slice and a wooden spatula.
Once the molds have been separated wash them and then sand with 400, 600 and then 800 grit paper. Wash in between each paper.

Now you are good to go. Making the two halves of the stock is the same as making the mold. I didn't use enough of the resin in the corners around the edges of the barrel channel and when iremoed it from the mold the cloth pulled away leaving the resin sitting in the mold, cosmetic only, not a structural problem.

There are heaps of videos and websites out there on fibreglass molding, but almost nothing on making gunstock. But fibreglass is fibreglass.

It is definetly not hard to do. The last bit of fibreglassing I did was 30 years ago when an Uncle showed my brother and I how to reinforce our canoe hull.

Hope all this helps.

Stu.

Re: Homemade fibreglass stock

That's awesome work! I've been thinking about pursuing something like this and what you've put down here really helps motivate. I do have a few more questions though.

Once you have molds done and prepped, I'm assuming you make the stock in the mold a half at a time then glue the two halves together right? Could you give a little bit more explanation on how you did that?

Also, how did you do the action area and barrel channel? Was it solid fiberglass which was then routered out when the two halves were put back together?

Was the forearm hollow? I know the butt was but what about the forearm?

Sorry for all the questions but now i'm excited!
