I was thinking that the drilled holes on both ends of the notches would take care of the rounded parts of the notch/tooth, and all that would be left to cut with the grinder would be straight cuts to remove the metal between the drilled holes. nobody I know has a plasma, i'll buy one some day. I've already cut the opening for the intake so am going to proceed the best I can.Dirtytires wrote: ↑August 22nd, 2018, 12:13 pmNot saying it can’t be done but I would find a friend with plasma or I’d change the design. Cutting a radius with a grinder is not something I would do when there are other options out there.
