Gosh, i could do with that as have an egg shaped 21 conical suzuki wheel brake drum [from road racing in an RT2 with RT2mx top end] & only have a small lathe. In saying that i could just spin one of my RT2 cylinders to de-stroke it [64mm DT1 crank] after trimming the fins in my 'cut off wheel' [don't tell anyone]. Had a 'big' lathe at work ['big' belt driven] & could do most anything in that. The 4 jaw chuck was about as much as i could lift to fit it on. Memories eh!!.
