I am totally new to machining, although I feel I have an understanding of the processes involved. I have just ordered a Grizzly G0765. Also ordered some tooling items from LMS. I have a machining project that inspired the lathe purchase, but am unsure on one of the cuts to be made.
It is basically a pulley shape. It is actually a roller for a sliding door. The bottom of the outer groove is curved, unlike a V-belt pulley, which has flat sides and flat bottom. I think I understand how to make the cuts for that flat bottomed V, but am unsure how to control the bit to create a radius at the bottom of the groove. Once I get the lathe and practice on it some, the answer may become apparent, but I thought some tips from experienced chip makers would help.
Thanks in advance, jp
