I used an old hydraulic cylinder with a pressure gauge

Largely because these components were lying around.
The torque,(or moment arm), applied the force.

PowerSport had a nice homemade dyno at OSH.
They used a load cell that fed data into a PC.
Great for auto logging data. I need to get up
there before it gets too cold and see how they
are doing.

Why not a pressure transduce to the PC from the
hydraulic cylinder?  I like this much more than the
bathroom scale, even if it is just a remote mounted
pressure gauge it is likely to be more accurate and
less likely to mechanically disconnect or something.
I like the idea of a "rigid" hydraulic link in a system
so the whole cradle can't go anywhere.
