thanks, its a lot clearer now. i noticed you used a similar design on your homemade focusser. very nice work.
last few questions on teflon and ebony formica.
i've seen a few scopes using teflon as clutch plates, is'nt teflon supposed to be the most slippery substance, how is it then used in clutches which needs a bit of friction?
would you have any idea on ebony star formica? read on the siderealtech site that it was used as a clutch.
is teflon available at bunnings or stores as sheets or blocks?
i've finally decided on using a split collar clutch around my steel shaft with a lever to compress and release it, thereby gripping or releasing the shaft. this collar will be fixed to my fork frame. in principle, it will do the same job as yours, providing slippage when needed, just a different type.
will post pics when done.
