Thanks for the compliments, . I'm just a hack machinist. I have worked in various industries and my dad taught me more than enough to get by with the mill and lathe. There is still a LOT I need to learn, but I can muddle through for now...
I'm going to use M3 "Greasegun" mags for this. The Thompson stick mags have a couple issues that make their use a little difficult. The issues could be dealt with, but the M3 mags don't require any modification and are excellent feeding mags. They look like a Sten mag on steroids.
For a magwell, I'm using one of the magazine conversion kits for the MAC-10. There is a kit that has a magwell and catch that replaces the original one on the MAC. I'm just going to trim the height to get the feed lips lined up with the barrel and weld it to the receiver. There's a similar kit for the M11/9.
Winn hooked me up with some RPK barrel blocks, awhile back. Those will fit the .45 barrel easily. I have an RPK lower handguard for it. I'm thinking about having Z-Recto do a Polish laminated stock, pistol grip, and upper handguard to match it.
I'm going to sandblast all the parts and parkerize the whole thing. After that it's going to get GunKote, but I'm torn between satin black or the GunMetal blue.
There's a lot of work being done on pistol caliber conversions lately. Vis, jungp, jpglee1 (if he can get those welds cleaned up... ) and a few others have some irons in the fire. When I get this finished, I will put together a scrapbook of what went into my conversion. There are a few issues to deal with, but I think I have most of them ironed out.
I'm considering dropping the original recoil spring assembly and making a new one that uses 1911 recoil springs. That would allow me to tune the action by using different "weight" springs. 1911 springs range from 6 to 24+ pounds, so tuning the recoil should be feasible.
I won't get any more work done on it for a couple of weeks, but I am bringing the parts with me to the shoot.
