Quote:I didn't move the marks, but I must have moved some mechanical axis away from the default position.So the index marks are truly irrelevant if I'm going to do a Goto alignment procedure anyway? Good.

Quote:Does anyone know what, if any, lubricant/grease is supposed to goes on the large aluminum cylinder (see 6th picture in http://astronomer.proboards.com/index.cgi?board=Equipment&action=display&... ) ? I'm having trouble with this on the DEC axis. I never actually removed the one on the RA axis so I had no problem.With super lube synthetic grease on it, it is difficult to put on, and very resistant to movement when it's on. This is still true but to a lesser extent when I remove most of the super lube from it. I wonder if it's supposed to have no lube , or a different kind of lube. I also have Super Lube Dri-Film lubricant which is a WD-40 like solution, I might try that, but am interested to know if anyone has insight on this...edit: I might use regular WD-40, I am not so sure about this dri-film stuff, as it leaves a fine teflon powder which has some not so nice properties.edit2: Certainly the geared part of the cylinder should have grease. I'm asking about the rest of it.
Quote:I want to sand and polish it since it got nearly stuck twice with super lube grease, and then with the dri-film, which was stressful.Should I use a silicon carbide sandpaper at 600 grit, then move to 1000 and 2500 grit?http://home.howstuffworks.com/polish-metal-sandpaper.htm
Quote:First and foremost is the fit of the ring gear. The metal to metal surfaces on the gear and the axis casting must be sanded and polished to fit better and smoothly. Once that is done, then you can move on to lubing things and should use SuperLube for this.

Quote:sneutrino: Hope you do not mind a minor sidetrack here but...Ed: Can I ask for a bit of clarification? You said:Quote:First and foremost is the fit of the ring gear. The metal to metal surfaces on the gear and the axis casting must be sanded and polished to fit better and smoothly. Once that is done, then you can move on to lubing things and should use SuperLube for this. To me that sounds like you are suggesting the surfaces be dry test-fit prior to applying lubricant. I am assuming this is incorrect.... is it?
Quote:EFT, if you have seen the internals, would you say that the Celestron CVX, and CGEM have significant mechanical improvements over the CG-5?
