Hi Bojan,
I used to work in a bearing centre and we had a customer who made massive solar panel tracking units for Telstra. He simply affixed light British Standard chain to the lower ring of the unit and drove the unit as per Garlitz's drive. The chain comes cheapest in a 10ft box with a joiner link. No bending, curves naturally, inexpensive, off the shelf. Tack welded every 3rd/4th link. "BS 06B-1" is heaps strong enough for the job, and a simple plate sprocket also readily available. (We went through the rack option first then came up with this method)

[QUOTE=bojan;968234]Looks good..

I was also thinking about rack (will have to be curved first.. if possible at all), normally used for sliding doors ( I have it on my gate)..

And.. I have one old, spare motor driver unit.
