???????? I was simply asking what would it take to run an airbrush off of an air pig. I happen to have one , you seem mechanically inclined, was just wondering if this was a possible thing. Not sure what you thought I was asking or exactly what you are responding to. sorry to bother ya
"Air pig" might not be a common enough phrase. So we're on the same page, I assume you're referring to a portable air tank you can fill from a separate compressor. I suspect it would work alright. You would need a way to fill it and you'd have to put a regulator on the output line. If you run your airbrush at a low enough pressure it should last a while, but you'll have to refill it every time pressure gets low. If you have a way of filling the air pig why not just use that?
I tried all of the cheap airbrush kits they sell at hobby stores and I hated them. Finally I sprung for a nice dual action, internal mix airbrush. I got the Iwata Neo from our local Hobby Lobby, and have enjoyed it every time I used it. Looks like they run about $60 right now, but I was able to use one of the many coupons shops like that have so I got it a bit cheaper. That is just the airbrush, a compressor, hose, regulator, fittings, etc will add on to the price. The compressor I had, I got all the rest from Harbor Freight. (It's hard to screw up even a cheap a hose or fitting.)
I run a hose up the stairs from the air compressor in my garage when I want to use it.
