OK first I would like to thank anyone for there replies.
Now the problem, I rebuild engines and do alot of bead blasting over the last 4 years I have burned up 3 compressor and 2 motors. They just cant handle running 4-6 hours a day and I have been buying the 60 gallon Kobalt and Rand compressors around 500 a pop. I know I need more but we nuy what we can afford. I have a Kobalt that is still working but I want to think ahead. I have a extra 60 gallon tank that ha a devilbis air pump on it and there trash. Again for what I do. A buddy of mine just gave me a Champion r-15 2 stage pump and 5hp 3 phase motor. 3 Phase not avaliable where I am. The 3 phase motor has 1750 rpm's with about a 8" dbl v belt pully on it and 1" shaft. I can find 5hp electric single phase motors for around 200, but they are way more rmp's in the 2250 to 3500 range. What do I need to do to make something work. I have fabricated a plate on top of the old compressor for the Champion pump to mount on. "its huge: but the motor rpm thing is driving me up the wall. It is a 175 psi pump with 22 cfm. I think it should hold up much better than the others if I can make it work. PLEASE GIVE ME SOME INPUT.
THANKS AGAIN,
JOHN GIBSON

A buddy of mine just gave me a Champion r-15 2 stage pump and 5hp 3 phase motor. 3 Phase not avaliable where I am. There are a couple of ways to run a 3 phase motor on single phase that a DIYer can do. Not cheap but maybe cheaper then a new compressor. The 3 phase motor has 1750 rpm's with about a 8" dbl v belt pully on it and 1" shaft. I can find 5hp electric single phase motors for around 200, but they are way more rmp's in the 2250 to 3500 range. You would change pulley size to adjust for RPM. It may cost no more then that to build a three phase adapter. The pros will have to weigh in on this.
