Well, it is happening, finally ..
The pier is designed to fit inside 2.3m Sirius dome, carrying my 10" Newtonian on EQ6 mount.
The fit will be pretty tight, only ~6cm clearance between the tube and the dome (to achieve this, the pier needs to be offset by 109mm from the centre of the dome).
However, the dome is planned for my future observatory in Seymour.. For now I will have this pier temporarily mounted on concrete slab here in Mt Waverley in the open, until I retire and finally move to the new residence... Looking forward to this
The concrete slab is still to be built.
I plan to cast the holes for 20mm dinabolts with plastic tubing (arranged in place by wooden template), to avoid drilling into concrete... not sure if anyone did this before.
