Yesterday I had to part off some aluminum (6061), 24mm diameter, and remembered that I had had endless trouble previously with this operation - regardless of material.

So this time I took off the quick change toolpost and re-installed the original four-way.? The parting off process went smoothly with none of the problems I'd encountered before.? It did get jammed once - I was running the motor too slowly.? (I don't have a low gear anymore.)? Didn't matter if I used oil or not, or went fast or slow.? It was as easy as any other operation.

Something about how the QC extends over the compound - one of the weak parts of these lathes - lessens the rigidity necessary to do this operation well.
