Hi Steve,
How about this idea. To fix the light leak, remove the focuser from the OTA, remove the mount from the focuser, clean the underside of the focuser mount, get some JB weld or similar aluminium 2part filler. Mix it up, Apply to area where light leaks in. Temporarily fit back into OTA so filler takes the shape of the tube (make sure you use release agent of some kind, gladwrap works well. Let dry, remove from OTA, trim off waste, repaint. Done!
I would probably try to do this on a dummy OTA. ie 2 segments of mdf cut to the required radius and covered with a section of tin or gal, or use an old cake tin or tupperware container, as long as it's the same dia as the OTA. The reason, you don't want the filler dripping onto your secondary or getting stuck on anything useful.
Cheers
Michael
