Robin, thanks for suggestion - that's exactly what was on my mind, so now I know it's not a stupid idea
I just have to work out the details - what kind of pipe (square or "L" or "U" channel profile), how many sections (I can't have it in one piece - too big for transport), how to assemble it in situ (welding for pipe? screws for bent "L" profile or "U" channel?)..
This will depend on my friend (the one with work shop) and his capabilities (or preferences..)
The part of this formula is also motorisation.. and how to mount the cogged belt or curved rack pinion on a dome - I liked your approach - I used similar interface for encoder on my dobson mount, this is way cheaper than the gear made to fit the existing situation, but quite good enough.
