An update on my project. I fiinally received the 2rpm motor from China, it does 2 1/2 revs/min on a fully charged 12v battery. I have decided to change the gearing to 1:1 to give me a bit more speed control a pwm controller. I also figured out a way to ensure the mount from the bottom arm to the tripod was very strong, a 1/4" t-nut held in place by a short 1/4" bolt that allowed enough thread left in the t-nut for the tripod screw.
I'll post some photos when complete, if we ever get some clear skies in Sydney again I can run some photo tests!
