For $400 or $700 you supply a system/gun to at least 3600PSI or even 4900PSI on a 90PSI input, like a simple shop compressor? I also don't understand your statement about (scavenging) your airsource supply. Should I call you or do you have a post or online site? What are your work hours?
Found your original message down a few posts but no pictures come up. I wish I could see the picture that you posted in the thread below! I read all the info you supplied and it gives me a clue as to the ratio your friend has built into the system. I don't understand your reference to the "wrist flick" and a few of them result in a boost from 3000PSI to 4500PSI? I guess the pictures would have helped

I'll give you a call after the 4th; hope you have a happy one!
Thank You in advance,
