The usual band saw tensioning devices are not only awkward to use but have no reference point. Relieving tension when the saw is idle (as recommended) is a chore, so one tends to forget about it. My solution is to make a wooden handle, as shown, to fit over the existing knob. I can now relieve the tension by cranking the handle a set number of turns and then return to the original tension by cranking the same number of turns in reverse.
