Felt anti-vibration pads

I was reading 'Choosing and Using a Schmidt-Cassegrain Telescope' by Rod Mollise and his recommendation to use felt between the tripod and mount head to reduce vibrations.
As I was planning to do some tinkering with the scope and accessories today I made a felt disk and also put some felt under the RA motor.

One benefit I noticed was that's it's now easier to use the Azimuth tripod adjustment bolts (especially if the leg/tray spreader is done up).

Whilst I was at it, I turned the RA  gear wheels around to reduce variations due to eccentricity of the RA worm shaft caused by those little grub screw fixings.
Also I have some thin plastic washers (plastic milk bottle) under the slow-mo flange so that it is not wearing metal to metal.
