well, just an update. I hooked it up to Air today.. I guess for $39 it's not bad but.. I had a few things to overcome, the Air hammer that it uses, is just an air hammer, and the trigger still works as the trigger, there was nothing in the manual about this, I thought that the trigger was bypassed but it's not.. so my fix was a zip tie on the trigger, works great now. the pedal is just a bleed off valve, so when you plug it in to air, it bleeds off the excess air out of a vent, until you step on the pedal, and then it will close the bleed off valve and it goes to the air hammer. once you get it going, it works pretty good. all I had was an old fender from my brothers KIA. I managed to flatten out 1 of the body lines and round it over kinda. I still need practice, but I'll have some uses for it.
