Topic tags/keywords: bandsaw question

I just got a 10” Craftsman bandsaw.
The book says to install the band, then adjust the tension but it doesn’t say how much tension it should have.
I made a few practice cuts on some oak, and it seemed to me that the blade wandered a bit, so I presume it needs to be tighter.
What is a good method to determine if it is correct?

1/4” deflection for a saw with a 6” depth of cut.

Highland Woodworking has a number of good, free articles. This one covers resawing, but includes a helpful description on bandsaw tuning:

Google “band saw setup” – basically the blade wandering does depend on tension, but it also depends on how the guide blocks are set up, how close the top ones are to the workpiece, and even on how quickly you feed the work into the blade. I have a 12” bandsaw and the largest blade it can hold is a 1/2”. I set my tension slightly higher than the notches they say. For example, if the blade is 1/4” I’ll set tension up at 3/8” mark. If you have to set the tension up higher than that, then something else is wrong.

your saw should have notches somewhere (possible inside if its similar to my craftsman model). If not, then when you google band saw setup you’ll find stuff about it. Some people go by the sound of the blade when it’s twanged, or by how much it deflects when you push it to one side. like i said, for me i just go up one notch. this also happens to be about the place where it feels sort of “finger tight” – like to push it any more I’m going to have to put in serious work :-)

Have your say...
