Attendees: TomT, JerryW, TimC, EdK, ChrisU, DavidH
TimC talking again about bringing in samples of Telescope Workshop stuff to monthly meetings, but tonight’s suggestions were to setup for a full meeting, during the long light evenings of the summer, discussing mirror and telescope creation and astrophotography. Gathering questions that members want to have answered ahead of time would determine meeting coverage.
TimC did a little more 320 grit grinding on the 8” donated mirror.
EdK brought in mirror, but no testing setup tonight. Ed has put in another 16 hours of polishing trying to widen spherical surface. See his email.
DavidH brought in the old Celestron German Equatorial Mount. David says too much grease and also that one piece was not screwed in far enough that caused the concern about too much slop in the wormgear. Now Jerry and David looking at drive system, Jerry brought in his drive controller, cables, drives from a Vixen GPD (great Polaris) mount, with a 12V battery cigarette lighter connection (Kendrick wheelchair type battery). Unfortunately, gear drive fell off table and bent a wormgear shaft. Art Harris was suggested as the man to consult with for repair.
ChrisU brought in his “Flaming Tomato” Dobsonian telescope and mount. He is putting on a home textured formica strip on the Declination circles for friction or stiction (static+friction?).
