About LinkBacksThank you Luc.
I guess your altitude bearing is similar with 2 roller bearings plus one teflon pad for friction. I meant to ask about the altitude but typed azimuth by mistake. But I am interested in your azimuth arrangement also.

Re: My little monster 625 mm
For altitude no teflon just roller bearings.
Braking is done between the wooden arm and the aluminum disc.

Re: My little monster 625 mm
That wooden arm, if I am interpreting correctly is a tangent drive that does not give a full altitude range drive or goto but rather a servo for fine motorised adjustment or servo tracking over a small range? Very clever design.
Thank you
best wishes

Beautiful telescope. First class. Did you also do the mirror yourself?
