Default Why do bandsaw blades break?

As for the 4x6 horizontal/vertical bandsaw, (lots of brands, all
pretty much identical) -- it is very difficult to get the tension
appropriately high. The knob on the tension screw is too small a
diameter to allow applying enough torque. Essentially, tighten it as
tight as you can manage, and it is likely not *too* far below the proper
tension. Hmmm ... perhaps a low profile thrust ball bearing under the
knob might help.

Good Luck,
DoN.

I wonder if the frame / wheels / bearings are as inadequately sized as the
tension knob. Maybe they knew the machine can't handle the proper tension
and intentionally undersized the knob rather than redesign it.

I drilled two more mounting holes in the fixed vise jaw so I can place it
very close to the blade to hold short pieces, or move it back to the
original position to cut angles.

When I cut long stock out in the driveway I have to find a spot where both
sides of the base contact the asphalt simultaneously when lowered or else it
won't cut square vertically. The base casting isn't neatly stiff enough to
resist twisting.

To support long stock I balance it on the saw and raise a jack to touch the
outer end(s). Then the jack will be near the balance point when I move the
stock to cut off an end. I've cut a smooth square end on 6x6 landscaping
timbers this way.
