The spider hub came together tonight- bit of a mare as it’s glued together with high strength retaining compound which gave me about a minute to assemble everything and try to align all the screw holes - needless to say it was a right panic not helped by a friend deciding to strike up conversation at the critical moment. Wish I hadn’t rushed it as it’s not perfectly aligned and not much I can do about it now but it’ll do I think.
It’s getting a bit hefty though which is a worry- 200g already but that’s all the chunky bits bar the mirror itself. A lot of that is the central 10mm stainless shaft- might think about replacing that with aluminium or at least drilling a bore all the way through.
the adjuster screws need to be shortened a bit too
