Default running a 5 hp motor on a "3 hp max single motor" ROTARY CONVERTER

@newsfe17.iad:

have a saw (unisaw, actually) I need to run. need to rip some 2x4's, to
a few various widths)

if I put a BRAND new blade on the saw, 24 tooth, what do you suppose
would happen if I try to start the saw up (being a manually-fed saw, it
starts with 'no load' of course) then rip those 2x4's with it?

I realize I "should" have a bigger rotary converter for the task (or
change the saw to a smaller 3 hp motor), but, as a 'stopgap measure',
might this work, or, uhh, what?

I have no -other- three-phase machines here (at the garage of my house)
I can start up on my ol' arco HD-3 model rotary-converter, either...

thanks for tips, ideas, and WAGS on this one, guys

My WAG is blade sharpness won't matter much. The converter will either
start it or not and I'm guessing it probably will. Trying it is the only
option. The running load related to your blade sharpness has some effect
but the saw should have enough power to cut that board just fine if you can
initially get it up to speed. If the converter has a relay that pulls
capacitors in and out during sawing, you're pushing it past it's limits.
