Seems my DeWalt portable bandsaw causes blades to break prematurely.

I read this whole thread and no one mentioned blade tension. I'm not
familiar with that bandsaw so don't know if tension is even adjustable,
but over tensioning will certainly cause blades to fail prematurely.

I would hope that it is adjustable for tension, since otherwise
the fit of the blade would have to be unusually precise. Weid-your-own
would be unlikely to fit. :-)

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.
