Hi All – I found an older Powermatic 66 tilting arbor saw that I want to check out being sold at auction. The saw has a 2HP, 3phase, 208-230/460V motor but my garage isn’t wired for 3 phase and I’m trying to figure out if I can use the saw as is with some type of converter or is it better to replace the motor? Also trying to figure out what costs are involved with each option. I’m new to the forum but have read lot of postings about table saws since I’m looking to purchase one and appreciate all the information everyone’s posted. Thanks for any advice!

Replace the motor. Shouldn't cost all that much, and the frames shopuld be an easy swap.
You can get a "phase converter" that will allow you run a 3- phase motr on single phase power, but I agree with the previous post, get a new motor.

Post a pic!
I would go with a rotary converter as it can power more than one machine at a time and relly opens up your options for used equipment. I got one to power my 12" jointer a couple of years ago and would do it again.

have seen a lot of posts about problems with phase converters, although fewer with the rotary type. There is an unavoidable loss of efficiency in the converters as well.
I say change the motor and the pulleys if necessary.
Must be a very early 66. The PM 65 had 2hp, 56C frame motors but I assumed the 66 had the special PM C flang that is currently used. Mine is a '84 with a 5HP, 145 C frame motor that uses an adaptor ring. If yours is the current mounting, a new single phase 3HP motor is about $350. You would be wise to purchase, make or steal a rotory phase converter. A 5/15 HP unit will work fine. I have been running a converter for about seven years, the absolute best " machine " I've purchased. You can pickup cheap three phase equipmet that others pass up. They are very easy and cheap to build or go to http://www.woodweb.com and place a WTB ad. I found mine for $300, the best money I ever spent.
