Hi guys looked at a Logan lathe this weekend its a model #955 but it is 3-phase and I only have 220 single.Think it is worth the $500 investment he is asking for it.And any suggestions on cheepest way to convert it or should I just hold on to my money and keep looking for a single phase lathe thats allready to roll im looking to spend between $500-$800.

Reply:I don't have a Logan, but I've heard a lot of good things about them. I hear they are almost as good as a Southbend. About the only thing electric (at least on my Atlas) is the motor. I can't believe a motor transplant to single phase would be very hard.I gave $600 for mine, back in 1972. It did come with a tool post grinder and some extras. If this Logan is in any shape at all, I'd think $500 is a great deal, even if it didn't come with anything else. My humble opinion, of course.
Reply:I can't say if it's worth $500 without taking a look at it in person but as far as converting to single phase that's no problem at all. You can use a rotary phase converter or there's several vfd's that take 220 single phase in and put 3 phase out. That's the route I went with my milling machine and I love it. I could have saved some money on my machine but I just had to have variable speed, But I can control the speed with the vfd so I could have just bought a step pulley machine. http://dealerselectric.com/mfg-subca...cID=165&mID=-1several options there, Just make sure you get the right size for your motor

Reply:Originally Posted by noriteIn addition with three phase you can plug reverse the motor. This means you can thread right up to a shoulder, hit reverse and the motor almost instantly stops and starts turning in the opposite direction, without damage to the motor. A single phase motor has to come to a complete stop before it can be reversed.
