Building an observatory. Design #7

An addendum to my previous design post. The builder dropped the motor units off for the stair lifts that he thought might be butchered to make an automated roof mechanism.

This first is the lighter weight one for the rack made from multiple steel plates. The pinion wheel here is the same.

The second is for the solid steel rack. This one also has lots of microswitches that are undamaged and might be useful as limit switches.

For the moment however they’re going to remain on one side. I want to get all the existing planned work completely before adding more. I just need to bear it in mind for the wiring and so on.
