Re: Backlash/Play in the Delta Time Position Control on a 2236

In the short wave radio receivers of my youth there was a common two speed tuning mechanism that used an epicyclic ball drive for maybe 6:1 reduction but there was also a peg and slot arrangement that forced the inner and outer to lock together after about 3/4 turn. The locked setting had a lot more friction.

I daresay there are other ingenious mechanisms for the same effect.
