has anyone tried to make a tire tread cutting machine ?
I assumed by "tire tread cutting machine" he meant grooving iron. Usually used for dirt track.
If he is talking about shaving the tire; I believe the term is Cutting or Sipeing; Speedway sells a Siper.
I believe Ol'Dawg cuts tires. I'll see if I can locate his site.
I think I remember reading something years back about sipeing tires, but don't recall where. (Maybe "Circle Track")
I've read posts from some of the kart guys "Feathering" their tires with a grinder.
I think you would be right Al, about using some sort of machine to turn the tire. Sort of like turning a piece of wood (or metal) on a lathe.
I'll see what I can find out.
