The motor on it now is a replacement 3/4hp, 1725 rpm. Based on what you and others have said here I'll be getting a 3450 rpm, 2 hp. Looking forward to it.
Sounds awesome. I hope it works out well. I've been tempted to do something similar myself. My saw is marketed as 1.5 hp, but it's a 13amp motor... 13amps at 120v gives 2hp at 100% efficiency; maybe it really is 1.5hp "real world"? Anyway, I'd been thinking up stepping up to a "true" 2hp or maybe 3hp 220v motor so I'm interested in how your experiment goes.
