RA is still tighter than DEC. ___end___ GENERAL COMMENT BY berkey: Thu Nov 07 00:41:56 GMT 2019 Based on some comments from Rob, another DEC train inspection was proformed. Not sure what happened but I am not unable to repoduce the issue I was seeing last week. Instead of a 1/4" gear train slip at the dec arm, I am not seeing <1mm and I am not even sure I am I am seeing that becasue I cant get my face close enough to watch in detail while bumping the spar. I think the only things that have changed since the big moves were seen was a slight balance change in the spar (but this was mostly in RA with very little DEC lever arm) and a change in the DEC clutch tightness. During this inspection I also had the worm gear box cover off and confrim good connection (no slop) between the gears. I was not able to get the lead screw boot off to inspect coupling leading to the arm, by removing its retaining cover. It feels like the rubber may be just good and stuck to the worm assemlby after decades, but I cant get a great look at it so I didnt want to force anything. To be picked back up when we have a second set of hands on the mountain. ___end___ ONSITE STAFF: berkey
