View Full Version : Carbon fiber stock idea

So I am in school to become a composits engineer. We get to design and do some lab stuff. I am thinking about taking one of my beater Mosin Nagants and building a custom carbon fiber stock. My thought is to build a aluminum frame with a tube cut in half to be the start of the barrel action bed, then tubing to build the rest of the frame, and fill large voids with strutural foam. What do you guys think, also any ideas? I could use some brain storming on it. I want to make an adjustable cheek rest, and likely some pre-built mount points. I may not leave it raw carbon fiber I will paint it likely

Do FAL furniture and I would love you forever.

I know nothing about Carbon Fiber, but an aluminum bedding frame would seem to be the first order of business, then a mold for forming the foam filler to be covered by the CF material?

OK, going back to my stick of wood and carving knife now. :D

I would love nothing more then to make a set for the FAL, but I don't have the time to do it right for the project. It would take a ton of molds, and tooling to make it right, and I am all about it being correct. I also don't like Aftermarket FALs. This is why I figured I would take a beater Mosin, and have some fun. Worst thing it goes make into the factory stock. Thanks guys. If it goes down l will post pics.

These are all awesome and great ideas for me to think about.

Here's a couple pics of some wood hand guards that I covered with a resin impregnated "carbon fiber" cloth. HG's were vacuum bagged to keep cloth tight to the parts, and cured under heat.
In the process of finishing them with clear polyurethane. They need several coats as the cloth tends to soak up the poly.
They need a few more coats to finish and smooth them out.
Didn't come out great...just had some really rough wood hg's laying around, and wanted to see what they'd look like with the composite "finish".
With a little work, I think a whole furniture set could be done, and although not for everyone, I think it would look pretty good.

What will a complete set be worth? I have a friend in South Africa that is making high end ($$$) carbon fibre bench rest stocks. Maybe I can talk him into doing some.

Far too resin-rich bro, those are going to be brittle as hell.

What you see is the clear coat.
Not resin.

By the way.
I've worked with this stuff a bit.
The vacuum bag sucks down to the part with an "absorbent" separated from the part with a breathable "bond breaker" cloth that doesn't stick to the resin. Excess resin is "squeezed" (by vacuum ) out of graphite cloth into the "absorbent".
The hg's are very strong and far from brittle.

I've got a pretty good handle on it...
Thanks tho.

Don't know why I'm defending myself here, but...
Maybe this will clarify things a bit for you.

Pic 1 is closeup of the same "carbon fiber" cloth used for hg's, but as a camera mount bracket for a skydiving helmet.
Same amount of resin. Roughly 15 layers of cloth versus the 2 used on hg's.
Pic 2 is a shot of the whole bracket.
Pic 3 is the the whole helmet.

Trust me. It's very strong. Carried a Sony Handicam through roughly 1000 skydives and BASE jumps.

There are the usual suspects to check out, Manners, et al.

A more recent offering has been for Tikkas from http://bollycompositestocks.com/

Dry bag or wet layup? Been dry bagging parts with decent luck. I won't trash talk, rather learn as like my carbon fiber skills to improve and shiny usually means I get slicker finish. If you get worked out throwing my crap in trash and pay you instead. Time is money.

Hueyville,

I take it you are using carbon fiber prepreg when you mention "dry bagging".

I am just finishing the composites technician program at OWATC in Ogden.

I was planning on doing L1A1 handguards for my advanced project but realized that I would have to have custom machined molds made to make the handguards correctly. Way too much money so I used some epoxy resin molding clay (the school had a very small quantity of this epoxy clay left and original manufacturer either doesn't make it anymore or won't sell to individuals; I called them trying to buy some and company never replied to my inquiries) to make a mold for M1911 grips and made a couple of sets of grips. The first set came out OK, second set not as well.

A set of carbon fiber furniture for L1A1 and FAL would be great.

Those look great! Any plans to do the short gas system hand guards and possibly the buttstock's? I would love to know the weight difference. I have a Stainless DSA and they would look awesome on that rifle, probably make up for the weight difference in the SS. I had a Ducati Monster I bought that the previous owner did in a lot of Carbon fiber and I fell in love with the stuff.
I had thought about doing a stock and hand guards up as a one off but too many projects now.
Yours look great, don't let the naysayers on here interfere with any plans you have or nothing would ever get to market. They would sell just fine and in small expensive quantities.

"dry bag" is vacuform I believe..but not sure.

carbon would look cool for sure. I wonder if the kevlar/carbon weave would look good as well?

here's a skimboard I built in CA before I escaped
