Another thing that was done in wartime I believe was they put metal tips on some of the stocks. Is this something that a few folks might be interested in. I know that there were some posts on tring to find the metal tipped stocks.

Aluminum Cast stocks

Re: Aluminum Cast stocks
Melted the last ones i did, and made these... Version 2.0 i guess 
! These are nearly identical, except for that i used a sand core keep the center from being solid. This was tricky.. I'll clean these up and see how they turn out! But for any future production, i built a nice steel core to sand cast with on the lathe. I want to give it a test tomorrow if i have the time , or the next day!

Re: Aluminum Cast stocks
REALLY screwed up welding them, re-start time ... I'll give my steel core a try!

Have you tried making it in one piece,hollow? ---bil

Re: Aluminum Cast stocks
Thanks 42 rocker
Tomorrow or monday I will start on a solid steel core that will be drilled through so that the long bolt slot that goes through the butt and the buffer cup will be casted into the casting too. This should provide a second face for which the core would be supported, and theoretically make the one-piece castings possible.
Yeah, i've had trouble forming the sand casting in a way that this could be done. The core needs to be supported in a way that it is "floating". Due to it's length, and only being supported by one face, this makes it very hard! I am going to scrap my current steel core, as it is but hollow piping. No more short-cuts, if i want this, i've got to get serious about it.Bil wrote:Have you tried making it in one piece,hollow? ---bil

Re: Aluminum Cast stocks
How does the weight compare to the wood stock?

Re: Aluminum Cast stocks
I'm just looking into making a permanent cement molding box. If i get the right formula for the mix, this will make my life much easier! The sand is frustrating to use! My teacher suggested i make CO2 cores, so i'm giving that a try monday. It is only good for 2-piece casting really... Although there are ways to do a 1-piece, i'm afraid the CO2 core may not be strong enough. If it fails monday, i will continue with the steel core i'm making on the lathe. I just finished facing the sides, and center-punched it to sit nice on the live center.
Classicmachine:
Compared to the wood, there is a weight difference, but it is still very light. I'll weigh it after i'm done making up this next one, but i doubt anything much beyond 2 pounds. I could be wrong, it is very light for it's size. Doing a one-piece casting does not allow for much to be done "hollowing wise" as the steal core has to be removable. But it can be done, so i will look into it.

Re: Aluminum Cast stocks
I still don't understand why you're messing with all of this. Oh well, to each their own.
Re: Aluminum Cast stocks
I think it is because he can! Still in school,the more you learn early,the better off you are.I would guess this is a project more about the casting process than actually making a usable buttstock.There are always those cast aluminium grip covers some say are real,some not.Learning to do casting properly is a skill that can come in handy,if you can learn on the schools dime ,so much the better.{or do you have pesos up there?Funny money,anyway] ---bil

Re: Aluminum Cast stocks
Monopoly money here Bil, cmon man, i thought we went over this!
Why you ask 12thWaffenSS? Wood buttstocks just seem too fragile for me, i don't want to beat it up. Aluminum is a cheap, durable alternative that you don't have to "baby". I'll probably end up just buying a german buffer+stock assembly from marstar in the end anyways. I am at no loss, i took apart a cheap yugo stock that already had a massive crack going down the center of it (would have probably split sooner or later).
Of my four classes this semester, 3 are metal fabrication and 1 is electronic systems. I have pretty much graduated high school, and am taking this semester fairly easy before i go to university in the fall.
I want to acquire as many hobbyist trade skills as possible before i leave school (as Bil had correctly assumed). I can now cast aluminum from sand, cast silver jewelry, TIG weld, MIG weld (flux core also), use a cutting torch, oxy-acetylene weld+braze (good to know when you're fooling around with water jackets), mill on both a vertical and horizontal milling machine, utilize a lathe, tap and thread, make springs, etc. Not too shabby if i do say so my self, makes building replacement parts possible which is way cheaper than buying them
