Obviously I am missing something .
Shadetreemotorcycle talks about needing a collet chuck for machining the PM globe valves ??
 I have looked at their castings and instructions I have and the castings are Hexagon not round
 I thought collet chucks are for round ? And hexagon usually goes in a three jaw .
Can some one please educate me as obviously i am doing something wrong in my workshop.

Cheers
Dennis
