Octaviu5:
I dont use 10 turn pots cause they reach an end. And AFAIK there is no way to remove it.
Quite right! I was thinking of picking a single turn of 360 degrees out of the 10 possible and using that. Making the mechanical stops have been done, but is rather a lot of metal work. More for government work!
My limited Google research shows robotics has a problem similar to yours and they have no immediate solution, either. Looks like yours may be the best fit.
I have some concern, though, relating to the sliding contact wearing the material when it passes over the open end points. I am used to carbon material embedded in some type of phenolic material. I see some pots are using a conductive plastic material for the resistor. Are yours made this way? They would probably wear better.
