So my girlfriend and I are buying a house soon and I've decided that I'm going to use the garage as a shop. I intend to build a small forge and metal furnace in order to make stuff, but I have one thing I want to make a shitload of. 80% lowers.
Does anyone know how much aluminum shrinks after casting? Have a CAD drawing for an AR lower, AK receiver (While iirc it can't be aluminum it can be forged steel), FAL receiver or even a G3/PTR91 receiver?
Also, general weapon smithing thread I guess.

the igs files open fine in solidworks, I never bothered putting CAD on my home computer. And the blueprint files are just pdfs and are decent. I'm not downloading some random exe though.
I want a home forge and machine shop...I just don't really want my own home...

Sweet, thanks bro! Once I get the house and get set up I'll post up to show the work. I suspect some people on /k/ will want a lower or 2.
Just found the shrinkage allowance for aluminum is between 1.4-2% per linear inch. That makes it a bit easier.
np, I'd post a pic of the solidworks file....but I made the mistake of running a recognize features and now I'm waiting for it to crash.
I should really update my computer. Gen 1 core i7 is really getting dated. Still puts my new work laptop to fucking shame though...

Zen is just around the corner mate. 8 cores with SMT, and if you get a polaris GPU at the same time you can use the OpenCL stuff built into solidworks/AutoCAD to speed up the process too.

Theres always new shit coming though. My main holdout is that I travel so much for work that I'd be spending money on shit I never use.
Oh fuck. Thats everything I buy...
Why do I own things again?

> in an attached garage

He never said it was attached.
If it is though, I'd suggest NOT doing that, OP.

Not an attached garage. If we get one with an attached garage the forge and other "hot tools" will be in the back yard under a small roof.
Cast aluminum without good heat control will be trash
