I work on Kitt Peak and we are in the middle of summer shutdown projects for the mountain. I have been tasked with cleaning and lubricating an old Meade ED127 refractor plastic focuser. The original lubricant in between the focuser tube and the tube housing has become semi rigid, almost gooey. Does anyone here have any experience with disassembly/ reassembly and cleaning of the focuser? Your help would be greatly appreciated! I will try to post pics after I go up to the mountain later today.
