CGEM vs. EQ6 Pro
Posted 23 August 2009 - 09:28 AM
The noise can be minimized by fine-tuning the mesh of the gear train and tweaking the worm alignment. Instructions are all over the EQ6 Users' Yahoo site, as well sites of some posters here and other places. Fairly easy to do, but the final few milimeters of adjustment of both the mesh and the worm can be frustrating; locking down the final location can shift the setup and result in binding or looseness that might be worse than it was at the start. Some folks get lucky and are done in less than 30 minutes including removing/reinstalling the motors to adjust by feel, some chase it for hours and hours. It's a task to keep the obsessive-compulsive tinkerers busy for a long time.

I searched youtube and found few vids demonstrating EQ5/6 mounts. Those seem to be pretty quiet when slewing But there is a significantly nasty sound when starting/stopping slewing (I wonder what that sound would be when operating well below -10C). Is that common with EQs and could changing the lubricants/bearings cure it?
No vid found showing CGEM.
There seem to be some threads here discussing over this noise issue which is pretty important to me (neighbor's bedroom less than 30ft away).
I might accept slightly higher slewing noise but start/stop should be free of extra noise.
It's not at all "nasty." "Barely audible" is more like it. If you want "nasty" have a listen to my ETX 125...
