Opened up the counterbore and slightly chamfered the threads. Happy to say it's a good fit, but not tight. Made the counterbore about the same as the others. My spindle is 1.8101", this counterbore is 1.8152" which is about the same as the other back plates I have.
With that out of the way, I will take down some of the diameter on the register side, down to roughly 67mm OD. Made a start on that this afternoon. Something isn't right, as cuts over 0.020" are causing a low frequency humming. Maybe the cutter height isn't quite right. Need to make a tool height gauge for this lathe. I know the height, but haven't made the gauge yet. A magnetic light I have mounted to the headstock was noticeably vibrating. So kept the DOC low and plodded along. Still managed to generate a few chips! Did a lot of vacuuming a couple of minutes after this picture.
