Clock drive clutch material
      #5728152 - 03/12/13 01:13 PM

My 20 year old OpticCraft drives have these fiber plates between the worm gear and the clutch plates that is getting very old. There's a bit of sticking whenever I'm sweeping the skies. I'm curious to know what others have used for replacing these things - it's almost like heavy duty cardboard or like a step down from masonite board... Any ideas?

Thanks
Roger

Cork in the old days? What about the stuff that C and M use today? I'm not sure what it is but somebody will come along with an actual answer!

Cork was common. Asbestos was sometimes used. I don't know of a current Meade or Celestron mount that uses slip clutches.

I thought I had read somewhere here that someone used auto gasket material. What about cutting up some teflon sheet from those thin cutting boards?

I was thinking of the ALT friction disc on my Celestron 8SE mount which lets the OTA take a bump or push and not trash the gear train.
