A friend of my son has a MR2 with drilled and slotted rotors. Can I turn those on a lathe ? I have a big old Anco and a Kwikway . Never had opportunity to try . I think the holes will make the bits jump ???

Shouldn't
Didn't when John lane and I were getting creative with some huge GpA ford stuff.
As usual with iron I like a new side to the carbide insert.

When cutting these kinds of rotors. You have what is call and interrupted cut. Depend how ridged your tooling is depending on how the tool pressure will transfer after the holes. If you run a high Sfpm(surface feet per minuet) speed and your tooling is not ridged. You will notice trailing after to holes. This because of the tool pressure changing. Make sure the tooling is solid. Then run your RPM around 75 and no more. Take .015 cuts at max. The lighter the cut the less tool pressure involved.
