Chainsaw is correct. Exspensive equipment is nice, but with files, hammers, basic hand tools, decent guns CAN be built. There was a Gun Digest article in 80 or 81, can't recall which, pertaining to gunsmiths in Afghanistan (or Pakistan... some "stan" anyhow), building reproduction Lugers, Lee Enfields and AK-47's, with only very basic, old school equipment, elbow grease and skill. Kabul, and the Kyhber pass area both have a huge cottage industry of gunsmiths. If THEY can build functional repeating weapons with limited tools, why can't the original poster? I doubt some of these middle eastern gunsmiths can even read or write, yet THEY can build a working AK-47 with BASIC hand tools, but you guys are telling the poster his idea is too exspensive and complicated, so forget it??? If I'm cutting a tree down, I prefer my Jonsered Chainsaw, as its easy on my back and cuts like a knife through butter, but I don't NEED it to drop the tree. I have an axe too!!! More than one way to skin a cat guys. . Here is a video..., poor quality, but you can see the work conditions, and old and new technology being used.
