762x39pro 5 Posted December 22, 2013 Report Share Posted December 22, 2013 Hello all Does anyone make and sell an 80% milled ak receiver? Or do any of you know where I can get a saw cut (demilled) milled ak receiver all the ones I find are torch cut and done so poorly you would need to buy 3 or 4 of them to put together one good (re-weld) milled receiver. This is just a curiosity on my part, I would like to try my hand at a re-weld or perhaps finishing out the 80% if I could find one. Quote Link to post Share on other sites
Rhodes1968 1,638 Posted December 22, 2013 Report Share Posted December 22, 2013 Check youtube, ran across a guy that does exactly that IIRC. Just search on milled AKs. Quote Link to post Share on other sites
Billybobf 50 Posted December 22, 2013 Report Share Posted December 22, 2013 I would like to watch! I was thinking about taking a cheap parts kit and making a receiver to convert it to run 30-06, the bolt would be the same but a longer gas rod and longer receiver, a mag well and a common double stack 30-06 mag Quote Link to post Share on other sites
Rhodes1968 1,638 Posted December 22, 2013 Report Share Posted December 22, 2013 308 is plenty and those can be had. Using '06 in a rcvr built for x39... I dunno. Quote Link to post Share on other sites
VR762Shooter 838 Posted December 23, 2013 Report Share Posted December 23, 2013 (edited) 308 is plenty and those can be had. Using '06 in a rcvr built for x39... I dunno. Yeah I think 30-06 in a x39 milled receiver will be a very violent relationship with a very explosive break-up (pun intended) Edited December 23, 2013 by VR6Shooter 2 Quote Link to post Share on other sites
Billybobf 50 Posted December 23, 2013 Report Share Posted December 23, 2013 gonna start my own thread... stead of jacking his. Quote Link to post Share on other sites
762x39pro 5 Posted December 23, 2013 Author Report Share Posted December 23, 2013 Oh well if any of you has a lead on saw cut milled receivers please pm me. Quote Link to post Share on other sites
762x39pro 5 Posted December 23, 2013 Author Report Share Posted December 23, 2013 10 demilled receivers for $75 www.apexgunparts.com Quote Link to post Share on other sites
762x39pro 5 Posted December 24, 2013 Author Report Share Posted December 24, 2013 Hmm after checking all the laws with regards to re welding demilled receivers and such I decided to give this a pass. Too much trouble to be worth it for me. Quote Link to post Share on other sites
Billybobf 50 Posted December 24, 2013 Report Share Posted December 24, 2013 Look for flats! 1.5mm flat for $35 from either ak builder or whatacountry Saw cut it at bends then weld it! Shoot buy the 1.5 flat and an 80% pre bent cut and weld the flat outside, then drill through. Make long pins and call it a super ak 1 Quote Link to post Share on other sites
Rhodes1968 1,638 Posted December 24, 2013 Report Share Posted December 24, 2013 The main problem with building a stamped from a flat is getting the proper heat treating. It will work without it but eventually it will fail. Quote Link to post Share on other sites
762x39pro 5 Posted December 24, 2013 Author Report Share Posted December 24, 2013 I have access to large flat laser machine at work than can cut metal up to 3/4 inch thick with no rough edges......perhaps I will buy a flat then copy it and cut one in 1mm titanium sheet. No need for heat treat with titanium then. bet I could do it, if any of you have a good print for a flat that is 100 % accurate I would like a copy of it. Hell I would build it just for shits and giggles....titanium sheet metal receiver ak.....hell yeah. Quote Link to post Share on other sites
unclejake 428 Posted December 25, 2013 Report Share Posted December 25, 2013 Now THAT would be interesting! Quote Link to post Share on other sites
Rhodes1968 1,638 Posted December 25, 2013 Report Share Posted December 25, 2013 I guess if you have access to a welding rig that will do Ti for the rails, cant see why not. Now a milled Ti rcvr .... Quote Link to post Share on other sites
762x39pro 5 Posted December 26, 2013 Author Report Share Posted December 26, 2013 Ordered Ti its will be on its way soon enough, if I cant get the rails welded in I guess I will need to do a screw build. 0.04in = 1.0160mm http://www.ebay.com/itm/TITANIUM-SHEET-6AL-4V-040-x-12-x-12-/261257624982 material is cheap enough if I screw it up....no big deal.

Billybobf 50 Posted December 26, 2013 Report Share Posted December 26, 2013 Tig welder with LOTS of argon! Something small like that, put it inside a comforter bag or other clear plastic bag, space bag, something like that. Takes some work to set that up tho. Good luck! I'd love to do the welding!

Some are way too soft to make a good receiver. Quote Link to post Share on other sites
Rhodes1968 1,638 Posted December 26, 2013 Report Share Posted December 26, 2013 If I recall what little metallurgy I know Ti is too brittle and must be an alloy, good catch on alloy selection. Quote Link to post Share on other sites
Shandlanos 1,470 Posted December 26, 2013 Report Share Posted December 26, 2013 If I recall what little metallurgy I know Ti is too brittle and must be an alloy, good catch on alloy selection. Some alloys are too soft, some are too hard/brittle. Good steel is a great material because it has a very high tensile strength - it isn't all that hard, but it's damned strong. I used to make chainmail, and for the fancy stuff generally used Grade 5 aerospace titanium - TIAL6V4. Had to be super careful bending that stuff, bend a ring 90 degrees and it breaks. Pure titanium, on the other hand, was almost as soft and malleable as aluminum. Quote Link to post Share on other sites

I got Titanium Sheet 6AL-4V - it seems i will need to hot or warm form this material as it will spring back a bit if cold formed.

Billybobf 50 Posted December 27, 2013 Report Share Posted December 27, 2013 I was thinking about getting a chunk of 1/16 thick chromoly, or even like 1/4 inch chromoly plate, if it was the 1/16 I would have to make internal rails, if it was 1/4 I would mill the rails, either way, make it in three seperate chunks, bolt it down to a set of trunions and weld them together. other thoughts included a really long receiver, and a much longer bolt carrier, for a long action caliber, up to and including a 50bmg or 12ga FH, either one with LOTS of R&D, but still fun. the longer bolt and bolt carrier would allow for a longer firing pin, allowing the trigger group to be back farther. thinking of complex recoil springs as well Quote Link to post Share on other sites

You'll probably end up with some interesting colors when you do so. That titanium alloy anodizes very nicely with heat. It's very easy to get blues, golds and greens out of it with a carefully controlled propane torch. Even heat from the friction of machining it will anodize the surface.
