That's been on my to do list for years , parting was always a pain . I used a sawzall With the lathe running slowly no problem by resting the motor to the box turret it worked well.Here's a link to the magazine cover mentioned above:

I think there's much less chance of binding , with the lathe turning against the revolving cutter going the opposite direction all the chips and the slot width is constantly the same there has to be almost no chance of binding. With the side cutting blade it has to be none .FWIW, I've had a lot of issues with sitting saws binding in the cut, more than with parting tools.
