501 forum posts 132 photos	I always make a cam and make the same mistake, its not so obvious until I've made it, then think it out the realize what I have done wrong. If I was making a hundred in a factory, not being a turner what a cockup I would of made. I have a 3.5mm offset, so I off set 3.5mm on the clock on a four jaw chuck, but that only gives me 1.75mm offset on the cam. Its logical to move 3.5mm and get 3.5mm, but it don't work out like that, sorry if this is a basic post. Bob.
