Bandsaw question


I've had a Grizzly G0555 since it first came out, and I am happy with it. I
replaced the tension spring with one from Iturra Designs. Usually I use
1/2" or 3/8" Timberwolf blades and have no problem with tracking, etc.
Changing a blade usually takes me about 5 - 10 minutes. Recently, I switched
to a 3/16 x 4TPI blade for some bandsaw box work and I have a *helluva* time
changing blades. It takes me quite a while to get the blade(s) where they
will track on the tires. It's almost like a balancing act to get the blade
into the right position on the tire to where it won't creep forward or
backward. Once I *do* get it tracking properly with the correct tension, it
stays that way - just takes me a lot longer than using wider blades.

Is this just user error or is this common with smaller blades. I hate to
think what I'd do if I switched to a 1/8" blade!

Thanx,

Vic

That's called a crown. Without it, or some other tracking system, the blade
will come off.

The crown in the rubber tires is suppose to be there. It helps the blade
track correctly. The blade will naturally track to the high point of the
crown, all things being adjusted properly. Belt sanders use the same
technique to keep the belt tracking in the center of the rollers.

Yes. I have a Craftsman belt sander with virtually no crown and the gouge
marks in the frame to prove it. :)

I have never used the less expensive bandsaws but I presume that they have a
rubber cover over the wheels. Most of the time the rubber is higher in the
middle which causes the blade to move over to one side as it runs. You might
try flattening the rubber with a little sandpaper to get the narrower blades
to stay in the middle.

Probably the crown on the tires is worn out from always using wider
blades, the narrow blade is riding on a small flat spot.
