Hi Steve,

Yes the idea is good and would have been simple to implement.

The following will also have to be considered :

- Endurance rating of the pot. This application is for endurance testing of a steering gear and each gear will be endured for 1 million cycles. This is a 24x7 machine.

- Zero set point. The setup does not have a fixed zero. The operator will load the gear, couple the drive, manually bring it to midpoint and press the zero button to mark that as the center point. Zero point is floating and thus cannot be accomodated with a fixed turn setup as in a pot.

( Sorry for not mentioning these upfront - but then I did not want to start the thread with an eloborate message )
