Thanks in advance. Spend most of my hobby time metalworking but
occasionally need to do something in wood. I am having trouble with my
bandsaw. It is an inexpensive RIGID. The problem is that it only cuts a
curve in one direction. If I go the other direction, the blade just twists
and it doesn't want to make the curve cut in the wood. I believe I have
adjusted the guides as recommended in the instructions. Am I doing
something wrong with the adjustment? How tight against the blade should the
guides be? Could it be the guides are out of square allowing the blade to
twist? Is it something more obvious that I am not seeing? Is it my cutting
The thickness of the material is irrelevant as to the blade width.
The band width and tooth set determines the minimum cutting radius,
which for a 1/2" blade, is generally about 5" in Diameter. If your
circles/curves are larger than 2.5" in Radius, then the set of your
teeth is probably fubar. If your curves are less than 2.5" in Radius,
then you're just going to twist the blade and remove the tooth set.
In that case, you need to go to a smaller blade width.
wider blade width generally equates to fewer TPI. Cutting 1/8" or 1/4"
material with 3 tpi wouldn't be a good idea, so I submit that thickness
of material is NOT irrelevant to the blade width, as the TPI is related
to the width of the blade. You want more than 1 tooth engaged in the
I can't say that I've ever seen this, but my first suspicion would be
that the set on your blade teeth is not symmetrical. Have you tried a
different blade? Is the band width small enough to allow cutting the
radius you desire? DAGS to find a chart listing the largest blade to
be used with a given radius cut.
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
