Motors installed and pier constructed.

Power supply (right)
Dome control (with open door)

Now that there is power to the observatory the motors for rotating the dome were installed.   The two motors were mounted as well as the power supply box and the dome control circuit.   I put the to electrical boxes in the same orientation as they were in the old observatory - mainly since the wires were already cut to right length to reach both motors from that location.

One of the motors. 

Last weekend one of our neighbors that I met in the local EAA group helped me weld together the parts for the pier.   He had some good ideas also that he contributed to the construction.   He had some scrap metal with a 90 degree bend in it that was a very nice fit (after cutting to shape) which worked out very nicely for a support on the top of the pier.  This will easily allow a wrench in under the mount to tighten wedge onto the top of the pier and make needed adjustments if needed later.   I should add that a plasma cutter is one of the coolest tools. Ever.  I got a chance to try his out, and it was amazing how easily it cut through solid steel.  It's like "lightning in a hose"!
I bought some primer and paint for the pie
r, so next thing is to paint the thing to keep it from getting rusty.

Very solid pier.  I don't think vibration should
be a problem - just dragging it out will!  (ready to paint).
