Dlbard, you would be amazed if you could see what i do with nothing more then my drill press, some files, my mig, and my dremel.
Some imagination, determination, and luck go a long way. How far have you gotten? I have only welded it up and i made the relief cuts for the buffer before i did that. then i cut the sear things off the bolt and my barrel is fitted and moves smoothly. I think i am gonna go with pirates fal design or make a fal fcg fit my grip. I am a fal guy and i know that fcg very well. Plus, no matter how much meat ya take off the hammer, it still hits hard thanks to a very strong spring.
Measure, think about it, measure again, think about it some more, measure again, then cut......."Oh S***!!!!"
