Thanks Greg;
The reason for this design was to keep the pot dry. I was thinking of
putting the pot and pendulum weight in a sealed box. The friction thing
seems to be a big concern and the pendulum length may end up to be a
compromise. I will probably experiment a bit to see if it has repeatable
performance before I build it.

Hi Joe,

With a 10' dish to aim, my guess is that you will need a
more precise position sensor than a pot with a weight on it.
That weight is going to swing a bit, and there is going to
be error introduced by the friction in the pot's shaft
bearing.  My limited experience with this sort of design
was moderately successful, but I was aiming a short yagi
at the time.

If you can anchor the "weight" end to something fixed,
that should help.  Also, pots don't like to get wet.

Just a suggestion,

Greg  KO6TH
