Modding the HBS

Just checking to see if I got the wiring right. Some modifications to the telescope HBS, Hydraulic Bearing System, to allow for a slower startup. Some new hydraulic valves installed by Mark, a few new relays added by me, and the job is done. Hopefully less sputter and spitting on startup to keep the oil off the drive tracks. The system is a classic relay logic controlled setup, seriously old-school.

With this last part in mind I noted that I would be climbing to the top of the Keck 2 dome.

All I needed to do was to take some photos and make some measurements. We want to install some weather instruments on top of the dome, given the harsh mountain conditions this must be properly planned and approved.

After the meeting Denny approaches me. “Can I come?” he asks. Denny is our network manager, in charge of our computer systems, he has never had an opportunity, or reason, to climb the dome. The top of the dome is just a bit spectacular, and it is a beautiful day, I can not blame him for wanting to go.
