I got a little more work done on the build over the last few days. I got the ejection port cleaned up some with files. I left it on the smaller side so I can open it up as needed. I never did get the die grinder yet. Since my build is going to look mostly like a suomi I decided to go ahead and use the original type charging handle. Since I'm using a thick receiver I'll need to either make a new taller lug or add some metal to the old one to make it tall enought to retract the bolt. I rough cut a slot .325" wide starting 1.29" from the back and 5.56" in length. I centered the slot by using a piece of angle iron and using the notch for the feed ramp. The long 5.56" length cocking slot actually extends to the back of the fireing pin and serves as the opening for the hammer as well. I decided a while ago to get a remington hammer and sear set up from a 870 or 1100. The remington hammer is thin so I shouldn't have to widen the cocking/hammer slot any. Thats where I'm at now, I"ll get a picture of the updates on in the morning.
