Well I have bought just about all of the buffs fromEW and I have only found one that will fit inbetween the fins on some cylinders and heads to polish the flats. It has an 1,8″ shaft and it comes in a set. I geuss you have to buy another set just to get one that fits and I know it is going to take more than just one to buff a couple of sets on cylinders and heads. Anybody got a better idea? Thanks!!!
