Re: How do I know if it's working?

The sidereal rate is 15 deg/hr.  If you have, or can borrow, a laser pointer, then tape it to the mount, let it run for a half hour, and measure how far the spot moves across the wall of your living room.  Compare the measured angle to the calculated angle.  That's what I've done.
