This is a detail on the north south adjustmed et up.

A is a piece of bar stock drilled every few inches to allow the "see-saw" arem to move up and down as the seasons change. I plan on replacing this with a linear actuator that will move this arm automaticly.

B is the main pivot point for north / south adjustment. It's a large nut / bolt that you must slightly loosen to facilitate north to south adjustment. THIS will not fly with my proposed modificatin. I will replace the bolt with a piece of 1" rod that will be attached / run through the "see-saw" arm, That rod will fit into two 4-Bolt flange bearings that will be bolted to the out sides of the rails
