Back again.

I am still worried about the rattling of my scopes declination motor, though the visual effect isn't that big.
I wonder how this sound comes about.
When i touch the holder of the worm i can feel the vibrations. But how can this come apart? The motor certainly can only spin left or right, or it may oscillate rapidly forth and back. Spinning left or right certainly does not make the gear drive vibrate. In fast motion the velocity is much higher.
So the motor must oscillate, maybe it gets to much forth back command in alternation.(The whole thing look very much like a violation of momentum conservation ;-))
To send the scope back to meade from germany is out of question, ( so i havent contacted my local dealer yet)
it would take months ( maybe years ) the get a repaired one.
So i am thinking about fixing the error myself.
May be some stuff of dampening material may be placed
besides the pivot spring, that pushes back the Worm at the gears.

What do you think?
