Lots of slop dec.

Something is definatly loose, but I dont understand what I am looking at well enough to know what to adjust or what might be broken. To address this in the short term I have tried to slightly optiomize the spar balance to work with the kcor calibration optics both in and out of the beam. Histocially the spar was balanced with ND in and cal pol out. But there is a resoanble big balance moment change when the cal pol is in the beam. Such that we the loose dec train we tended to get guiding issues during the cals. This probally wont address the issue Greg saw yesterday afternoon where he lost guiding ever 30-40 minutes. The Dec clutch is also slightly looser now than it had been. Based at looking at how the DEC arm moves relative to the spar I think our drive train damage may have roots in a dec clutch that was too tight; so the dec drive train slipped instead of the clutch. ___end___ GENERAL COMMENT BY berkey: Tue Oct 29 01:50:02 GMT 2019 Foggy and raining.
