Your right Doc, and this thing gets quite difficult to get some things into place...like moving those darn tubes that are not at 90 degree angles, bout drove me crazy.
I ended up making a full scale model of 2/3 of the OTA to make sure that the tubes stayed out of the light path.
And I'm still going to wait for the big machined pieces to arrive to assemble and again check the tube lengths before cutting up that $800 in Carbon Fiber tubes...
