I am making a (simple?) alt-az mount for my Meade 6" and Orion 4.7" refractors. I intend to just place a 4x4 post into the ground and make all out of treated wood, so it can be left out this summer. Are there any rules of thumb for the minimum desirable diameter of the circles for each of the axis bearings? I am comfortable with woodworking and don't mind experimenting, but would like advice. I will start with 2" PVC pipe for the altitude, and can really go any size on azimuth.
Also, any suggestions for the depth of the semi circles to be cut to supprt the azimuth bearings? Should it be a full 1/2 circle?
Thanks
Tom
