For the first part, you say the dowel will cast a shadow at noon - I always thought at noon the only shadow would be the diameter of the dowel shadow. Am I wrong?

Please check picture if I have the concept right.

Assuming I can draw the shadow cast by the dowel, how do I make sure the Mount is aligned exactly in that direction?

Really appreciate the info on home position.
I worked out the zero point is 3" mark on the west side of the scale (150 (+10 time offset x 15) degrees east - 153 degrees longitude at the viewing location), but don't quite understand what to do with that information yet.
