I have some aluminum "A" belt profile V belt pulleys to make from 6061 T6. Could the grooves be plunge cut (one at a time) with a single cutter ground to an A groove profile? The lathe I have is a Leblond
I tried doing just this with my 10EE a few years back. I had a bit of chatter, so I used a cutoff tool to rough out the depth in the center of the groove, worked great.
I Think I'll give that a try karl.
It's a function of cutting length (length of edge actually cutting) and rigidy of your lathe. A simple way to half the cutting length is to make your form-tool smaller than required, plunge cut and then move left and right to get the right width.
You have to know how rigid your lathe is.

We use this method often in steel
