looking for valve stem chamfering fixture for my Sioux 645. I attached a few pictures of my machine and what the valve stem chamfering fixture looks like for this machine. See first picture. I'm hoping somebody has one laying around that's not being used or might know who I can contact. As seen in picture two. I can not use the updated version valve stem chamfering fixture-bracket. If you have a better easier way, Please contact me. Also, can this machine be converted to a Replacement Collet Style Chuck Spindle?Thanks for looking,
