I know I could glue a strain gauge on the band itself to do the
measurement, but I want to be able to mount and unmount the strain
gauge on different bands.
The actual thing I am measuring is the tension in a bandsaw blade.
Strain means stretching, and a clamped-on item can
stretch if the bandsaw blade stretches OR if the blade
simply twists or bows or straightens. Or, if the clamp slips.
Measuring the force on the wheel axle is a better indication of
tension, and it's a simple matter of calibrating a spring to do
that. If you want to get fancy, consider a hydraulic cylinder in
series with the tensioning screw, and measure the hydraulic
pressure with a gage or transducer.
