they make a little tension guide for tuning sailboat rigging (so you
can get the mast in column straight). pretty cheap, sort of like a
spring scale on a simple piece of sheet metal.

I felt an involuntary cold shudder at "sailboat", but they
aren't -that- expensive:

It looks like car serpentine belt tension gauges don't go high enough.
