Hi Silv, just a bit of clarification here, the curved rod does not rotate. The nut on the rod turns. A barn door tracker can be built with a straight rod that does turn although it won't be quite as accurate in tracking over any long length but the earth only turns 15 degrees per hour so not a real problem. For widefeild it is more than adequate though and a lot easier to build.
Your location tells me you are 18 km from me. Whereabouts in Auckland are you ? Might be able to assist, I have a reasonably full home workshop downstairs. Haven't built a barn door but looks like a fun thing to do
.
Cheers
