Do you have any pictures of the tabs for the butt joint?
You could probably save a fair bit of weight by vacum bagging it.... then it's just a small step to a one piece stock with a latex bladder

you dont need a big demand...just one person who wants something different.....good mate of mine has a savage in 7mm mag.... the stock was stupidly soft n flexi,whole rifle silly light,barrel is soda straw thin....it used to boot the crap out of him....his mate "leaded it" for him.....we couldnt work out why it rattled,so took action out of stock...it literally had pieces of wheel weights cut and sat in stock cavities!!!!!!
I hot glue gunned them into place...worked a treat.stock is now stiff and the added weight helps with recoil issue...funny how he still uses his .308 more LOL.
when I say soda straw thin.....my std 1 in 20 thread protector will go part way onto his non threaded muzzle.
I did similar with my .22 but used hot glue and lead shot in the fore end,stopped the dreaded wobble when the scope was would up to 7 power and was better for running bunnies with the extra weight forward.worked well.
If you want to achieve the highest level of rigidity and lightweightness, have the mould split horizontally rather than vertically with all the inletting and bottom metal moulded in the two halves. Much harder to make the mould , certain shape would be hard to make and would need a three or for part mould and there is that seem line to sand down and maybe paint over but no need to mock around with inletting.
I believe the old brown precision stocks used to be made like that.
Also vacuum bagging or pressure blader use would improve the strength and lightweightness .
i tried some of the cannedfoam to bulk out my foam decoys-hot shit mama -some went from flat to more chins than a hong kong phone book.ive a parrie hen who is now so fat she reminds me of a poli sittin on the shit house!
@Chilli_Dog No I didn't get any photos of tabs, but will take more detailed pictures when I build the carbon fibre stock.
Would love to try vacuum bag, but unfortunately I don't have a vacuum pump.
I am not sure those vacuum bags would work for a a mold like that unless you use them on each half of the mould first, then let the resin dry, then removing the vaccuum bags and sticking the two Hal together.
You can look at resin infusion as well. That is another way of doing it.
In additon to some of what others have said you can do pretty budget vacuum bagging, I have used the plastic bags from mattresses, cut out and taped to the top of the mold. You have to make sure its bunched up enough to go into tha cavity without stretching. I used a vacuum cleaner, it was a karcher one which seems to have a bypass so the motor didn't overheat. Peel plies and bleeder plies help too
I just use a very cheap plastic hand pump for the vacuum. Works very well with my vacuum bagging attempts with peel ply and bleeder fabric.
I got an vacuum pump out of an old fridge. plerfect for this type thing, and easily available.
I will try and get a photo. very simple, and very grunty .
if you leave the mold open on the rear and barrel channel you can glue the two halves together oce the resin has gone off enough to be able to trim the molds. that way the bond is a little stronger as the resin is chemically bonding both sides together vs mechanically
Hey all, I am still planning to go ahead and make a carbon fiber stock, but unfortunately I got stuck half way through moving house with COVID-19, so all my tools etc.. have been packed away. Hopefully we can move once at level 3 lockdown, then first project will be to make a carbon fiber stock. Added to this I have been busy at work being part of the essential service group.
Thanks,
primo!
Did you find when you made the mold that you had any issue with shrinkage of the resin?
Sako's method of making the carbonlight stock is pretty cool. Foam core, seamless carbon socks for the layers they have a video on youtube but don't give away all their secrets.

is that loose carbon sock that the sako factory is using freely available?
Iv only seen sheets available
I had a quick look on line and found this.

Mean as man!
Great skills @Robojaz . Very impressive
Hey @Robojaz did you ever get any further on your second stock?
Tapping my foot here how’s the move gone? @Robojaz
