I've been looking for years for someone who could put together the electronics for using a strain gauge... Load Cells are pretty cheap and more than adequate in accuracy, but getting someone who can put together the electronics to take the readout and put it on a display seems to be impossible... The mechanics for this would be simple to machine, and you would have -one- torquemeter for all classes... with much higher resolution than our current devices... (for the most part...)

If -anyone- out there can -really- do this, or knows someone who can, I for one am very interested...
