Speed Tip

I use the Pro-Wheel Mandrel to remove material from the inner tread, but
also for removal of material from the inside center of the wheel. I use a
flat or chisel blade on an Exacto knife and very gently and slowly apply it
to the surface from which I am removing material. I mount my mandrel in a
Porter-Cable cordless drill mounted upside down in a vise. I place a tie
wrap around the trigger. The Porter-Cable drill has a battery that slides on
rather than being inserted. With the drill upside down and a tie wrap around
the trigger I slide my battery slightly away from the contacts to turn the
drill off and slide it forward to engage the contacts to turn it on. With
this set up and the Pro-Wheel Mandrel I have a great wheel lathe. I have
been able to remove approximately 15-20 percent of the wheel weight, which
is a big advantage. Caution - If you smell burning plastic you are pressing
on the wheel too hard.
