Topic tags/keywords: question bandsaw

My shop is in an unheated garage. This week the temps have been in the high 40’s to low 50’s in the garage. With a sweater and a portable heater it’s tolerable. I have a Grizzly G0513 bandsaw that up till now has given me no trouble. Yesterday I was sawing something and just as as I was finishing my cut I heard a loud bang and then a rubbing noise. I looked all around and found the tire on the lower wheel had come off and the blade was riding on the wheel. The wheels are cast aluminum. Can these shrink in the cold to the point where the tire can come off? I put the tire back on and while running I can it lifting just after and before the blade comes into contact. It’s more pronounced as the blades lifts off, maybe half an inch. It seems to settle back down when stopped. I can see how the tire might slip off. It’s never happened before so I’m wondering if the wheel shrunk and the circumference decreased. Or is this just a coincidental wearing out of the tire?

You can glue those tires on with automotive GOOP brand adhesive (from the auto parts store). I did this on my big Grizz to get me through the project and have never put the new tires I ordered on! It’s been several months now. I don’t think your wheels shrank enough to cause this.

More likely the tire stretched.

At those temperatures, thats’s not cold enough to shrink. Most likely your tire stretched. I’d glue it on.

It is most certainly not the cold that is causing your tire problems.

Rubber tires become hard and brittle during cold but it will expand slightly when it’s hot/ exposed to heat. Have you tried using urethane tires?
