why not just buy a 100% lower?...@ 55.00bucks @ RGUNS...yeck my friend would charge me atleast that to complete a 80% lower..:/millling machines are not cheap...even for the cheap ones..and it does help to know how to use them and read blue prints and have the right mics...i have put a few ak kits together and benning is right about the heat treating...but its not to hard...really all that needs heat treated on a ak flat is the fire control group holes...also you dont need a bending jig...all you have to do is scribe along the bottom of the flat with a good straight edge & cutting tool..i do this by getting my measurements right on the flat..drawing lines down the flat(masking tape)works good...then remeasure..then take my die grinder w/ cutting wheel...and going very slow...stay with the line...all you need is a good half way deep lines across the flat...when done...just fold...then weld...of course weld your rails in first
I found a website that showed how to complete an 80% lower with nothing more then a drill press. All the hard machining has already been done. Your press would need a bed of some sort to hold it and you'd need a way to set it up. We're talking movements of .001" or less.
If the pain is lacking so is the discipline...
