Re: Unable to fully lock RA axis on G11
|
It’s
not supposed to “fully” lock!.. I have Michael Herman’s high friction clutch
discs and a perfectly working G11 and with enough force, it’ll move..
It
doesn’t take much force on the knobs to sufficiently tighten the clutches..

Unable to fully lock RA axis on G11
?
Chances are your clutch discs are very oil and/or severely worn. You
will need to unscrew the clutch locks all the way off and pull the shaft up and
out of the mount to inspect. Remember the order of the knob, washers are
bearings and put back in the same order. Try wiping down the disc pad with
alcohol or some other solvent. If the discs are worn like a phonograph record,
they may need to be replaced. You can give them some extra life by doing a
light sanding and again wiping clean. You will need to clean the respective
upper and lower contact surfaces as well. But I would suggest ordering new ones
from Lomandy if they are really worn. This should give you some extra stiction
and allow the locks to grip down on something less slippery.
