Thanks Rolf, I had to do the same to save every gram.
I wanted to mention that the UTA might need reinforcement. I found that the four supports aren't sufficient to keep the secondary rigid at different orientations.
the weight of the secondary mirror actually warps the 18mm ply by a few microns, and that's sufficient to throw a laser off the primary at different orientations, and this is even though I terminated the strings very close to the 4 supports.
what is the weight of your 10inch truss?
with the new 3inch focuser and stepper motor, along with a bigger mirror, won't the weight be quite a bit more than the 10inch?
what stage are you at?
