Can Slotted/drilled rotors be turned? Yet? Page: 1
Jan 12, 2010#0183;#32;I''ve literally done hundreds of them, cup wheel on a tool post grinder makes short work of them. I have even seen it done by hand with a 4 1/2quot; angle grinder equipped with a cup wheel on the lathe within a few tenths of runout. Thats how we did flywheels to get that blanchard ground look. Any machine shop can do it, its no secret.
