Q & A: Bandsaw Tire True-Up

Bandsaw Tire True-Up

Q:

How can I fix a bandsaw tire with irregularities that
bump the blade? I’m getting a lot of side-to-side
movement with the blade.

A:

Truing the hard rubber tire that goes around the rim
of each bandsaw wheel should solve your problem.
There are several ways to do this, but the one I like to use
comes from my turning background.

First, unplug your saw and remove the bandsaw blade.
Clamp a block of wood to the frame of the bandsaw, near
the tire’s outside edge and perpendicular to the wheel, to
serve as a tool rest. Spin the wheel to make sure it doesn’t
rub against your tool rest. Then have an assistant slowly turn
the bandsaw wheel by hand while you hold a sharp chisel on
the wooden tool rest. Shave the tire true, making a scraping
cut with the chisel. Remember that you want a slight crown
in the tire for best blade tracking. Watch your fingers so
they don’t get caught in the spinning wheel.
