Thanks Rolf, yep it still is sort of a test as I have to redo the bottom part of the UTA due to that incorrect slot I made for the focuser.
So will square it up once assembled. I was thinking of using butter paper and light through the focuser to do a basic alignment and will then use star tests.

Brendan, the secondary assembly comes off easily by just removing the 3 wing nuts because its actually 2 parts, the mirror with the holder comes off. So I have access to the secondary if needed without disturbing the wires.
Only bits left now are to measure the upper and lower truss lengths.
Trevor here has kindly offered to machine the carbon fibre truss ends for me. still in 2 minds of whether to use 16mm pultruded or 20mm woven CF tubes.
