Aluminium absorbs a lot of heat when welding so its susceptible to warping if you are not careful. We've largely addressed this issue by building rigid templates in which individual components are mounted and then welded in situ. My fabricator is also a perfectionist on more levels than I care to list and so his "so so" welds are better than I could even dream of doing.
The major OTA components will be joined in the next week or so, (working on the primary mirror mount and its attachment plates at the moment), and I am confident that there will be less than a 2mm error over the 2400mm length. Better than I hoped for by a long shot.
I'll add a few more pics shortly.
