Hi Gary,
Thanks for your reply.
Your words have provoked a bit of a rethink of my azimuth idea. With the way I've been thinking, it would prove difficult to engage the timing belt when the ground board and rocker box are coupled.
The thickness of the rocker box is 30mm (15mm hardwood ply was used throughout). Cutting a recess into the rocker box may be a good option, especially if located towards the posterior of the rocker box. That is because the mirror box stores inside the rocker box - see pic. The clearances, both in storage mode and in-use mode, would work if the encoder is recessed. Might only be a small amount too, the recess that needs to be cut. The gap between the mirror box and rocker box may well be in the order of 30mm.
However, I'm not keen on making the pivot bolt smaller than what I already have. Is there a larger pivot you have, or make a bushing to accomodate a larger bore pulley onto the existing pivot bolt? Maybe I misread your suggestion in pivot bolt. Come to think of it, my pivot bolt may actually be an M8 bolt.
Alex.
