I think that I need your advice. I am building a dosonian scope like Alice and it is finally coming together. I have all of the major components assembled, but I have not painted it or installed the Ebony Star.
The problem is that when I lower the optical tube the altitude bearings run off the rocker box traces to the left. And when I raise the optical tube up to the zenith then it runs off the rocker box to the right. This is consistent and not random.
I thought that maybe I had incorrectly mounted the parts, but everything seems to measure ok. I painstakingly remounted the rocker box traces to make sure that they were correct. I installed some small teflon keepers to keep the altitude bearings from running off track.
Currently when I set the OTA onto the rocker box, the altitude bearings do not sit straight with the rocker box traces. And when I pull the optical tube down and to one side the altitude bearings jumps up out of the traces.
Clearly something is not right. Please advise.
