Well if I knew how to edit my thing, I wanted to add that as a CNC machinist he can probaly just program the machine to make a continuos output of them and walk away just like that.

i learned how to operate a early this century cinncinatti belt driven lathe. it looked like it came over on the mayflower but it was a damn fine lathe. the qev is wayyy overkill but it sounds so damn good when it exhaust the pilot. the gun is very powerful. when i get some barrel butter this weekend ill shoot my bullets and take some video. should post it saturday evening. so far 3/8 inch bolt thru 2x10 wood at very close range.


the bullets are light. take 20 seconds on the lathe. i can make stainless steel ones in about 30 seconds. want to try the aluminum ones first since they are a lot cheaper to make. have no idea how they will be on damage. but the stainless ones should be awesome.

I like cannons which look like they were designed with some kind of ergonomics in mind ^_^

I know you said it's for ramming down the ammo but... have you had a go at firing the RPG bit? :wink:

Black steel ought to do the trick for bullets.I know I pick up scraps from a friend to mess around with all the time.I have an old Atlas(also belt driven)The old dog is about as inaccurate as it gets.I'm usually off a full 1/8".The chuck is lopsided and the bit holder wobbles.Lucky me I machine PVC so I use my pocket knife and wood tools 8)
