I just opened up the I.D. of 3 flat washers to fit over my rocker tool post to bring the 5/16" tool up to center, because I do not have a rocker for it. No scrap laying around that was 3/8" to make a rocker for it. It was a little trickey chucking up a flat washer and cutting the I.D. without cutting the chuck jaws. I put a stop on the bed so I would not hit the jaws, worked out great, and no marks on the jaws, came real close though. Tried to turn a piece of round and it was nice and smooth cut. I need to order my quick change tool soon, but for now it works. No need to face cut the washers for the right height, it just was a lucky day I guess, not too many of those come along, but I will take it.
