I am 100% in agreament with Rich, think about it!! A wheel has machined teeth on its outside edge, these machined surfaces are made to close tolerances, i wont go into the theory of the likes of cycloidal curves etc but why risk any form of damage by using a chuck with hardened steel jaws. Its an easy job to make a wood chuck as Rich says, regards OCRichmccarty said:What are you hoping to use the 6-jaw for? I've had very good luck using a MDF faceplate on the lathe for boring the center of wheels or holding a French barrel for rebushing. Mount a thick piece of MDF to a faceplate and then turn a recess into the wheel JUST fits. It will hold tight enough if you turn carefully. If you turn the recess fresh every time you remount the faceplate, you should be able to get near perfect centers.
