I suspect I need a new blade but I figured I'd post my experience for
input. This morning my bandsaw blade was tracking fine. Later I cut
some cardboard for the trash. Immediately after that, my blade
starting drifting to the right. The second I touch wood to the blade,
it starts to drift. Generally this is a sign of a bad blade but the
change in behavior was immediate and I'm hard pressed to think that
cardboard damaged the blade. It appears to be properly aligned. Any
thoughts?

Jeff.. Unless you jammed the cardboard in a guide or something, I'd suspect the
blade, but I've never had one suddenly drift a lot.. it's usually a gradual
thing..

Check both wheels and all the guides for bits of cardboard and buy a box
cutter..

Check all your adjustments and check in particular check where the blade is
tracking on the wheels. If the blade tracks too far forward or back on the
wheel it can drift more than normal. Running the saw can also decrease the
tension on the blade and allow it to go off center and or drift.

First, check the guides and make sure that they're at the proper
clearance--some saws have enough free movement that raising or
lowering the guides can put pressure on the blade.

Second, were you sawing the same species before and after? My saw
tracks nice and straight in maple and walnut and douglas fir and
poplar but drifts all over the place in lyptus for example.

I don't think the guides moved. The blade is not touching them.

I was sawing plywood templates before and after. (Well, after it was
*attempts* at templates. The saw is currently unusable)

I checked tracking. The blade is right in the center of the top and
bottom wheels.

By chance did you happen to hit a staple while cutting up the cardboard?

I thought I was careful but I'm beginning to think I did hit a staple.
Let's put it this way: If it's not the blade, then I have NO IDEA how
to correct this problem. Everything else seems fine.

Three most common causes of blade not tracking properly:

1. Blade too loose
2. Upper wheel not properly adjusted
3. Improperly adjusted blade support bearing

If none of those, then I'd try a new blade. Especially if it takes more
than normal effort to push the plywood through the blade when cutting..

In that case, I'd change the blade before changing a lot of setting on the saw..

Sort of like having a computer problem and reformatting your drive to try
solving it.. might have just been one little setting or something and it could
have been corrected without drastic methods..

I changed the blade and my cuts were fine. Must've hit a stable.

Never pass up an opportunity to buy a new tool..

There must be an expensive cardboard cutting system out there..

Someone gave me a box cutter with a light... like I'm gonna be out somewhere in

There is, it's called a "bandsaw." See how well it worked with the
cardboard? It wasn't until the guy hit a stable that the thing stopped
working. I'd stop working too if I hit a stable. Poor animals...

I'd prefer a lantern myself, but then again I don't go sneaking around at
night cutting boxes.

What, you're supposed to cut bands with it? Actually, very specialized
bandsaws are used in commercial bakeries to slice bread just before its
bagged up. And you know they're used in butcher shops too.

don't rule out the cause ,to be the cardboard, it is very abrasive.
use a box knife next time.

Not if you keep the stream of water tight enough. There just wouldn't
be time for the cardboard to get wet.

I've always had the "drive up ATMs with Braille" thing explained to me
as being for blind people who are riding in taxis or being driven
around. They shouldn't be expected to just give their card and PIN to
some random person, so they just ride in the back behind the driver
and do their thing like any other passenger.
