GENERAL COMMENT BY mcotter: Sun Aug 21 01:54:45 GMT 2022
No observing today due to areas of the dome floor being resurfaced. The Spar RA control mechanism has been removed from the Spar and was left for me on a bench in the control room to rebuild.

The RA mechanism was rebuilt utilizing the new motor/worm spring tension system that allows more access room for routine maintenance and adjustments. The RA is beginning to show signs of wear so the next time it is rebuilt new bearings should be installed throughout the mechanism. Also the friction cam rollers are showing signs of wear. Consideration should be made to have a new set of friction cam components made, then when the RA is rebuilt again the new components may be substituted and the worn ones sent out for refinishing then shipped back to MLSO as a spare set.

GENERAL COMMENT BY mcotter: Sun Aug 21 02:12:31 GMT 2022
Marc Starling was in today and applied the second coat to the second half of the dome floor, as well as painting in the Control Room and Clean Room. When he had completed the floor he saw that he had left only two heaters on in the dome. To ensure that the temperature was maintained Marc S. set up a heater in the dome vestibule blowing into the dome area. He needed to run an extension cord from the Control Room to the dome vestibule by putting the cord outside through the West door and up the stairs into the exterior vestibule door. The doors were able to be closed and locked but it was a tight fit.
