Re: Depth of cuts
What sort of carbide are you using? I've never had good luck with the 0 degree rake brazed carbide. I hear that it wants to run really fast.

0.002¡± is way too low. I run 0.015¡±-0.020¡± at a minimum for the hardest materials. Material? Speeds? What size is your motor?

Depth of cuts
I have a simple question. How deep of cuts do you normally make?
I have a 1949 vintage SB9C, with 6 speeds. I replaced the 1/4 hp motor with a 1/2 HP one. I use carbide a lot, but HSS still gets used

Re: V Belt
I have a link belt on my SB9c and it slips a lot. In the machining environment, it's impossible to keep oil off the pullies. It's smooth, but if it doesn't transfer the power...
