Had a bit of a rest from pushing glass and did a bit of work on the uta and made up the secondary holder. Its just a 8" circle of ply held flat by 3 lengths of 25 x 1mm aluminium spider. The spider is attached to 3 dovetail slides and there is a length of 3/16" threaded rod through the middle for fine adjustment.

In the meantime I started reading ATM book 1 for the 3rd time. You know how I said the mirror was done, well after reading ATM for a bit, maybe its not so done after all. So, I did 2 x 1 hour sessions at 10rpm and no weight and the surface improved no end. I may do another hour or two then tackle the slight hump in the middle.
