I rip 3/4" walnut on my Jet 14" bandsaw with a 1/2"blade. It's been
going great for a year (ripped about 500 feet) with no adjustments made.
(If it ain't broke, don't fix it) Well, I thought I'd give the saw a
treat for the new year and put on a new blade. Now the &%#@ing thing
wanders all over the place and I can't get it to rip using the fence.
Sooooo, I put the old blade back on and now it's running smoothly again.
Both blades came from the same shop. Any guesses what's happening?
What Leon said !
Also, not uncommon at all to get a bad blade. Poor welds being my most
common complaint. Seems like fro every good blade I've bought locally,
I have gotten two that weren't worth a darn.
Gotta try ordering some good ones sometime.
DAGS for bandsaw blade drift. Assuming it tracks properly and the tension
is set properly, each blade has its own drift. Once you determine what
your's is, set your fence for the drift and straight cuts are in your
Each blade has its own drift angle. Mark a line parallel to the edge of a
board. Cut along this line freehand until blade is cutting straight down the
line. Cut off the saw and adjust the fence to edge of the board. This fence
is now adjusted to how that blade cuts.
For a really good book on this, jigs, tuning up your bandsaw, etc., pick up
the "Bandsaw Handbook", by Mark Duginske.

Probably a length / elastic modulus variation. Simpler bandsaws are very
cross-dependent between tension and tracking settings. Re-tension it
equally after changing the belt and the wheel position might now be
different enough to throw the tracking out. I've even seen saws where
cleaning accumulated dust from around the upper wheel mount was enough
to cant the tracking over a bit.
Whenever you've changed one setting, you really need to work through the
list again - tension, tracking and right out to the guides. You can't
just hot-swap one at a time.
