Made a carbon stock as a project for my graduation, a prototype and a project for the future 👍🏻 nice work sako

Can you send us a photo? [e-mail]

I think they should make carbon fiber gun (and fiberglass) stocks, by first molding the carbon, and then saturating that with molten glass... if kilned properly, and with the right type of glass, it would be like a rock, it would powderize into dust, and not break in cracks.... if it could be broken at all. Soft glass is good for blow molding, but for solid molds, borosilicate may work, if the mold was hot, and vibrated, while the glass was poured, to eliminate any bubbles and pockets. Even more control with colors that way, borosilicate pipes are strong, you need to hit them hard with a hammer if they are kilned right to break, and that's without the fiber skeleton inside The inner part could be omitted that way, or could be aluminum or something light and strong, and heat resistant, although glass melts before metal.

[@nickhorton785]

Great information. The weave even provides a wood grain appearance too😁

[@VexChoccyMilk]

A bit of visual interest over painting.

[@youcanthandlethetruth6976]

They actually do make the stock from two separate pieces. It's the foam core that's made in two separate pieces, and then that's covered by a Carbon sleeve. Under a vacuum, it is then sealed and fused with resin.

[@mattcat2218]

What kind of foam do you think they use?

[@youcanthandlethetruth6976]

@@mattcat2218 There's a video about how they manufacture the carbon fiber stocks, I haven't seen it in a while so I don't recall offhand. But the foam isn't some special foam that I remember. It was just a dense foam that was later covered with the carbon sleeve and then lacquered with that resin.

[@Humbulla93]

@@mattcat2218 probably XPS -> extruded poly styrene, as it´s highly resistant to compression

[@hvuu1628]

so how well does it age? i assume the epoxy resin would not age to the point of being brittle and shattering?

[@doncunningham3124]

How many layers of carbon fiber are involved here? With 2 or 3 layers and a high density foam core (Stock) I'd imagine that would be atiquite for this particular application. The final reveal is definitely nice though. Especially with a matte or satin finish. Great idea!👍

[@jerrysponagle3881]

Make me one for a Remington model 742 Woodsmaster .308 and I will test it out for you. If it is half as durable as my mentioned deer hunting rifle, oh ya! Don't forget cheek rest...the basket weave design would be over the top. Squared fore-stock, not rounded.

[@groomlake51]

That lady with no gloves😳I just can’t stop itching my self watching her. If people only knew the level of ITCH raw carbon fiber produces 🤬

[@Learning_disability]

She i probably used to it tho

[@doncunningham3124]

I've been working with carbon fiber for years. I don't recall any skin irritation from raw, dry CF. However, the dust produced from sanding or grinding resin infused and cured carbon fiber products is another story. Cheers!

[@smokken10]

No gloves is a "not do" in any fiber job. This will delaminate after 15 years. BTW , carbon fibers wil acumulate in the body to anybody who dont use gloves.

[@jani8362]

Awesome!

[@byjumtobole4718]

Wahoo... carbon fibre gun body, 22lr body I need, will u sir deliver it I live in India....good work

[@vastosbicycles8325]

shocked to see the worker doesn't wear glove. I see the fingers are black. The two guys don't wear glove as well.

[@ericb.4358]

There real secret to carbon fiber strength and bonding integrity is the carbon fiber to resin ratio (by weight).

[@asdfjkl981]

that is not true.

[@Schairiebwdifb]

@@asdfjkl981 it actually is, too much resign and it’s heavier and has less strength because it’s more resign then the compound material carbon fibre, too little and the carbon will be flexible and not as strong, get it right and the direction of the carbon fibre weaves along with the resign make the perfect formula to be stronger the steel and lighter then aluminium.

[@asdfjkl981]

@@Schairiebwdifb It is not. there is no "too much" because you cure it under vacuum between two layers that push any excess resin out of the fiber. BTW prepreg already is soaked in resin and only placed in the mold, evacuated and cured. And with a resin infusion process you evacuate the fibre in the mold and than let the resin soak through until the part is fully soaked and than also cured. and those are the 2 main processes thet are used. The only way you can have too much resin is if you brusch the resin on the fiber and let it air cure without vacuum but that is not proper carbon fiber, it is an idiot wasting good material.

[@Schairiebwdifb]

@@asdfjkl981 well a process used in the boating work is like the way we use fibreglass, you put resign down, then your material, then resign, then your material. You can easily put too much resign on this way, the vacuum way is more expensive.

[@doncunningham3124]

Hello. Let's not forget about weave and fiber strand direction. The integrity of carbon fiber relies on it's tensile and compression strength properties. If these are not taken into consideration the resin saturation level isn't all that important. Just saying.👍

[@richg1221]

How do I get one for my Sako AV?

[@kenwithaK]

theres nothing prettier than a raw carbon finish.

[@doncunningham3124]

How about a smokin' hot swimsuit model holding something with a raw carbon finish?

[@jackspradt1562]

@@doncunningham3124 yes. pussy is better

[@Dont_uh_Panic]

My A7 would like one of those.

[@LudwigsPrecision]

there are draw backs even if its a solid system. weight. you want light inte the right spots, a light stock could fu@@ you up. recoil won't be the same, in that you get a new line in your shooting so light aint the deal. a combo in your caliber and shooting style tho.

[@doncunningham3124]

Yes! Thank you!

[@djustice5252]

Does anyone know if they make them for Howa 1500???

[@leksasdf]

Sako makes their own rifles... I really doubt they would make stocks for other manufacturers...

[@asdfjkl981]

Of course they do not!

[@dillonmclaughlin402]

Im making one for my 1500

[@antonb8422]

Bahahahaha. Idiot

[@josephgomes8543]

Now, in 2021 Howa has their own; i just got one. It took a LONG time to get here. It looks very similar to Sako's. It's called the Cardon Fiber Stalker and i got mine in 6.5 Creedmore. Testing so far has been interesting. During the break in process i was able to get very small groups with a couple of loads. Also you might check out STOCKY"S as they are now making a carbon fiber stock.

[@ronliebermann]

Carbon fiber is great stuff. But the price of carbon fiber is being held artificially high so that it won’t compete with other materials like lumber and plastic. The crude oil industry, dominated by a few players like Saudi Oil, and Standard Oil, won’t allow carbon fiber to succeed. And yes, you’ll say that Standard Oil, the giant monopoly, was broken-up by Washington D.C. But it’s the opposite. Standard Oil destroyed Washington. The Standard Oil monopoly still exists through shell companies. That’s where we got Shell Oil. If you look at the raw material costs for carbon fiber, you’ll see that they’re very low. But carbon fiber sells at a markup of fifty times over cost; with no explanation. However there is an explanation: Crude Oil. If the carbon fiber factories weren’t hampered by the Mafia, then prices would drop eighty percent. Then lots of things could be made. Carbon fiber clothes, automobiles, flooring, wallpaper, and tents. But the Mafia would sell less crude oil. The crude oil guys employ hit-men who enforce the Standard Oil monopoly. And those same guys own Washington.

[@JH-jo9wt]

Most of the carbon fiber comes from chemical giant Toray in Japan - well the good stuff anyway

[@danielrocca4915]

I have a Sako Finnlight 85 300wm and the stock has degraded, it is very sticky and cannot be used. I have made multiple complaints and never received a response. I will never buy a Sako rifle again

[@msb2948]

I too experienced this with my Finnlight so I spray painted it in camo colors and if that gives out there are several tape wraps that can be used.

[@JH-jo9wt]

Take it to FBT in Austria

[@JeSsSe66]

Itchy

[@Cayscasi]

Save your money, buy a Browning.

[@bazzatazza1087]

Browning are fine rifles but not as accurate. I find the trigger much nicer on a Sako as well

[@VexChoccyMilk]

Save your money, throw rocks.

[@malcolmballistictool]

Browning is a mediocre rifle with a top tier finish.
