wheel by use of the hand wheel at the front of the
fluting fixture until the correct angle for grinding is
obtained, then use the lever to rock the bit back and
forth into the wheel and at the same time turn bit with

and locking in place by use of hand nut screw provided.
Swing bit into the wheel by use of handle on top of
