Hi Gary,
Here's what you've asked for:
1: Ground board thickness is 15mm
2: Rocker box and ground board clearance is 3mm, plus 1mm for the laminate sheet.
3: Az. bolt is M8 & shaft is 65mm. Pic shows bolt used and the inside of of the rocker box' pivot nut:
4: Min. clearance of mirror box over Az. bolt is 16mm
5: Inside of rockerbox:
Underside of ground board pivot bolt head:
6: Clearance between stacked mirror box and rocker box is 30mm:
Whole width of stacked mirror box:
This pic shows the underside of the mirror box, where the posterior of the mirror box is clear of any obstructions from its centre. The black wire is the lead of the heating strap around the primary:
I've also noticed that the pivot bolt turns WITH the rocker box when the rocker box is moved.
This last pic shows the clearance between the mirror box and the rocker box with the trunnions in place and the scope pointing to zenith:
