• rotating said work piece;
• and
• bringing said rotating work piece into contact with said machining tool.

A work piece holder comprising:

• a spindle;
• an adapter body having an axial bore;
• a translating portion located within and translatable relative to said axial bore of said adapter body, said translating portion having a proximal end for coupling with a retention knob collet of the spindle and a distal end for attaching to a collet;
