I would stay away from Delta. They have been having trouble with their parts department for more than a year and is looking like they never will sell parts again. As far a checking the saw if you could get the seller to plug the machine in and turn it on it should be alright. For the most part if a machine looks like it has been taken care of it probably was. They almost never break down. Powermatic is a great brand but you might watch to see if is 3 phase as a lot of big companies use powermatic. That isn't a problem but makes more expense getting it usable. You would have to have some kind of phase converter to run it off of your household current.many thanks for the replies -- had been looking at that grizzly --
steve -- found a couple of used on craigs list -- how do you tell its still a good tool ? are there tests / measurements you should do ? take a test piece of wood ?
i found a 8" powermatic 90's vintage and a slightly newer delta DJ20 --
appreciate your thoughts and experience --
If the HP of the motor is the same, it wouldn't matter if it was three phase or not. In a factory that has three phase power it is just cheaper on the electric bill to run a machine on three phase. Find out what HP motor the three phase motor is and see that the HP on the single phase motor is the same. You would be able to get 220V single phase at your house.from steve -- but you might watch to see if is 3 phase as a lot of big companies use powermatic.

the powermatic was originally a commercial unit with a 3 phase motor -- the seller said he would change it to a single phase for residential use -- will the capabilities of the jointer suffer in the process ??
