Hi Peter, I have seen many types of motorised pots
in appliances, with some types the pot device can
be separated from the motor/gearbox part, usually by
2 bent over metal tags. The pot part had a standard
round shaft with one flat. I'm sure you could get a
variable cap with this size shaft, and with some easy
fiddling fit it to the motor unit.
