Hey guys!
Well, I need to make a bunch of 5/8" X 1/8" pulleys.Each one with a 1/4" hole previously bored out of the center on the lathe. I looked around and cant seem to find them for sale so I thought I'd use the Ol' Tormach.

I'd like to chuck up the 5/8" round bar in the mill's collet and use a mounted cutoff blade to slice off disks as the Z axis feeds downward after each pulley is parted. The parting blade will have a radius built in so I can make the groove as well. Here's the goal.

I do have Mach3 Turn so ive been considering tricking it into doing the job but I dont know enough about the terminology to do this effectively. For some reason the grooving wizard is telling me my tool is too wide for the groove - they are the same. Why would this be? (bonus question).
