I would like to buy a rig tension gauge for wires and rods up to 12mm
(15/32"). Tho most common I found on the market are for diameters up to
5mm (3/16") with the exception of a professional device for bridges,
elevators, etc. (Portable Cable Tension Meter for cables up to 7/8")
which - of course - is great but would cost a little fortune.

Any friendly suggestion?
Daniel
