Q & A: Bandsaw Tire True-Up

RATE THIS:

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.
