Right..which turns out to be more like..you want about 20 gallons or more at 125psi with a compressor that has a quick recovery rate.
I laughed a bit when I saw Stan'* compressor picture. Reason is..many of those large standup compressors had turtle recovery rates and made up for it in the tank size and price. If you do your homework and buy the right large upright compressor, you can supply the world with air...like a dealership.
(Which..knowing that nut...he'* got the good one)
