    Thank 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.

    For altitude no teflon just roller bearings.

    Braking is done between the wooden arm and the aluminum disc.

    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?
