thanks tomg,
do lowes or home depot sell air pedal that i need?

I don't think they would...but if you search on line i bet you can find one easily. I'd also try ebay, if you use that.....just make sure you get one you can step on and it stays in the open position....you could always put a ball valve on the outside of the cabinet in the air supply aswell....that way you can turn it on or off if you cant find a foot pedal. Good luck!

look up the websites for Grainger and McMaster Carr for the pneumatic foot switches you need.

I think the control valve method sounds like a great conversion for a finger trigger. The blaster I borrow has a foot pedal that is attached to a control vlave with a spring hooked to it to pull it closed when you let up on the foot bar. Its very simple and works well but just installing a valve sounds so much easir and just as effective. why re invent the wheel!

Yep, whatever works....they do make a pedal that once stepped on stays open keeping the air flow open, and once you press it back it shuts it of. BUT, why buy an exspensive pedal when a ball valve is $3.00 at home depot

i like the way you think tomg, $3 sounds real good
cheers
