Hey ya I'm new on here wasn't sure where I can introduce myself but this spring I'm planning on building an air compressor. I'm only limited to an 110v outlet.
what I have:
An 1.5 hp 115/230v 1725rpm motor of an old rolair compressor

What I plan to get
A harbor freight pump at 1050rpm pushes 10.5cfm at 90psi
A tank off of Craigslist a 30 gallon.

So before I mess things up. Would this work
According to the calculation the pump has a 12 inch pulley
If I put a 7.25 pulley on the century motor it would spin the pump at 1042.2 rpm and I would barley make the max on this pump. Question now is this possible. And ups and down.

I am not sure whether this is going
