Spent plenty of (volunteer) time fixing multiple woes for a donated 114GT reflector to my society. I'll forgo the gruesome details.
All looking good. But the clock drive emulation of this alt-az emits a constant rather irritating buzz from both axis. I think the tension bolts are not too tight.
The RA drive emulation seems to work, but can I remove the buzzing, or do they all make this noise by default? Is it worth my while to do a lengthy tear-down just to inject some grease into the 2 gears?
Thanks to all you pros for a look.
