[sdiy] Potentiometer torque

[David Moylan]

Found a neoprene washer at my local hardware store that works great. 
Will have to see how it goes over time, if there's any movement in the 
washer that reduces the friction, but so far so good.  Two stacked would 
allow the knob to hold them in place, but it added too much friction and 
started to feel like it was binding.
