(ATM) Cheap Clock Drive

[rglwp@attme.cnet.att.com (L W Phillips)]

Some months ago there was a discussion here about using the dial on a kitchen
timer to drive a scope's polar axis. Another idea occurs to me: directly
drive the polar axis using one of those timers used to turn lights on and
off at preset times. The model I have has a synchronous motor and is geared to
rotate the dial once in 24 hours. The dial pulls off, so the shaft could then
be connected to the polar axis.

A rough test indicates that at least 30 oz-in of torque is available
from the shaft of the one I have.

I admit I have not tried this (don't have a suitable scope).
