Strain gauge to measure bandsaw tension

How do you make a strain gauge device that measures the strain (change
in length) of a metal band by clamping the gauge device onto the metal
band. The gauge would be an analog bridge strain gauge that would
have to have pads that allow them to be clamped on the metal band, but
the material that the gauge device was made of would have to have
little effect on the total resistance to elongation of the band, since
the band strain vs. force is what is being measured.
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. I
found I could buy a mechanical strain gauge to do the measurement, but
find that I can buy a used strain gauge meter for much less and if I
can make a gauge, I will have a strain gauge meter for use in other
applications. Also, I believe it could potentially be more accurate
also.
