Hello everyone! I've asked around on a few different forums for some advice about this but didn't get anything satisfactory. Since what I'm asking about is pretty much all machining, I figured this was the place to come!
I am going to build a Galil ARM. The Galil's receiver is based off of a Valmet Rk 62 Receiver, which is based off of an milled AK47 receiver. I was considering buying a Galil receiver, but they're grossly expensive, costing $400 - $600. Even 80%s are quite pricey. However, the proper sized chunk of 4140 can be bought off of SpeedyMetals for $150.
I've been looking over some CAD files for an AK47 receiver, as well as the original blueprints for the AK47 and the Galil which I managed to find online. The only available model for the Galil receiver was hosted on GrabCAD, and got taken down a long time ago. I've started on reconstructing it. I have basically all of the information necessary to make the receiver, besides spending several hours modeling it. But I'm not sure I have the skill necessary to manufacture it.
At my university, I have free access to a state of the art machine shop. I am familiar with using a lathe, and know the basics of using a mill. However, the AK receiver is quite complicated. It involves lots of intricate cuts, including very precise keyset cuts for the ejector/rail area and floor of the receiver, and other things that I'm not even sure how to do, like the circular cuts for the locking lugs.
Anyways, I guess my question boils down to this:
Should I even bother with attempting this? I figured that since the AK47 is such an old design, and was produced on 50s era hardware, it couldn't be extremely difficult. However I'm not so sure about that anymore. Can anyone give me some information on what it takes to mill one of these receivers?
Here are some screenshots
