    Start grinding by moving the wheel into the test bar close to the chuck where the most runout of the test bars is. Use caution when grinding because you are grinding wheel and you cannot use the steady rest. You need to slowly plunge grind until you have the test bar round. Doesn t matter what size you make it just carefully grind the test bar round in the one spot.
