Has anyone had occasion to make an adapter for a Valenite insert mill? I have a Valenite 539 to adapt to the spindle in my Eklind milling head that uses a modified B3 collet. The interesting problem is machining the drive ears. The best I can come up with is to thread the holder, make a disc with the drive ears, and screw it on. Anyone have a more elegant solution?
