All,
I had the sawdust flying this weekend. This OTA was designed around a 6.3" F/10 Ukraine lens from Surplus Shed. The cell is different in that it would be somewhat difficult to make it "push-pull". I decided to go with shims behind the mounting plate for alignment. Very easy to align if the OTA is square. I was originally going to use the cell for alignment (that's the reason for the "fancy" arms that keep the cell in place) but opted for the lens mount plate instead. I will make a retaining ring in the future to replace the "arms". The focuser is collimatable.
A dew shield is forthcoming and I will do the filler/sand/paint thing soon.
