Also finding out drill bit diameters to countersink tubes. What I thought was 1 inch Aloy was closer to 28 mm.

Hi Neil,
I"m following your prototype closely, very enjoyable. I use star nuts to attach the tubes to the rings and they provide plenty of stability. Along with the focuser board attached with two screws at top and bottom and the tubes sitting in bored seats nothing will move.
Over here in North America, we have problems with varying tube sizes too, I now have 25mm, 1 inch, and 26mm forstner bits for drilling tube seats as the 1" tubes I order are not always exactly 1".
Keep up the good work, I see elements of Albert Highe's ideas in your prototype.
