    Default AK.45 is ALMOST finished...

    This weekend, I got most of the important things done. The extractor is tweaked and seems to be functioning, the barrel is pinned, the mag catch works, the top cover fits, I got the handguards fitted and the retainer notch cut, and I threw some cheapo Krylon satin black on it to keep it from rusting while I'm in WV at the shoot.



    It looks bent, but my camera likes to do a fisheye thing if you're not directly over the subject.

    There are still a couple minor things to do, but I'll get them taken care of during the week.

    While fitting the carrier to clear the mag lips, I managed to mill through the weld that was securing the bolt in the carrier! I soldered it back in place and it feels much more solid now. The bolt was only welded at the stipper lug on the bottom. When I tapped the carrier with anything metal, I swear I could feel the stem of the bolt moving in the carrier. Now it's soldered solid through the whole surface inside the carrier.

    I had to slightly modify the feed lips of the magazine to get the damn thing to feed properly. I squeeked 0.050" off the top of the lips in the mill, and that was all it needed.


    I also got the Plum 74 finished. I already had it assembled, but had to make up an axis pin retainer plate.



    I have a bunch of Barnaul 5.45 to break this one in with. I can't wait to fire both of these rifles!!!!

    I used a Robert Ibe 0.050" Battle Blank for the receiver.

    http://bentmetal.homestead.com/bentmetal.html

    Construction was almost identical to a standard build, but I didn't cut the mag opening until the trunnion was riveted and the barrel was installed. I did this to get the front of the magazine about 1/8" behind the breech of the barrel. If I had moved it about 1/4" back, I probably wouldn't have had to modify the magazine. As it is, I trimmed the feed lips of the mag down 0.050" or just a touch more to get the thing to feed properly. I can cycle it by hand and every round will strip and the bolt will close. When I pull back, the round catches the ejector just right and flips out of the receiver as it should.

    When I cut the mag opening, I actually milled the trunnion out with a carbide ball end mill. I just kept making deeper passes until I had milled off the bolt lugs. With the trunnion in place, I was able to thin out the sides to allow the magazine to slide in.

    I couldn't use a standard receiver or flat for this combination of parts, because the magwell dimples would prevent the magazine from going in far enough. The bent blank is really nice to work with, so I highly recommend dealing with Robert. For a 9mm, you could probably get away with a standard receiver or flat, but you would want to weld a patch in the magwell hole.

    There are a few things that I did just to get it ready before the WV shoot. Once I find out if it works, I'll go back and fabricate a couple different parts to replace the quickies.

    I can't wait for the shoot in WV to test fire it. After doing this project, I know what I would do different. It wasn't really difficult, but took a LOT of planning and trial fitting to get where it is. If it successfully fires and stays together, I will call it a complete success.
