On reflection, the top tubes which will take focuser, secondary and finder feel strong enough.

With some internal bracing, the bottom tubes which house the primary mirrors feel like they should well be strong enough, taking into account the fact that the primary mount itself is going to add some rigidity, too.

The center tubes are the longest, have the other two hanging off them and will need to accommodate whatever mounting rings or cradle I choose to make.

Therefore, I will only re-glass those center sections.

(The two parts of one primary mirror cell are curing in the warm cabinet right now. I'll paint them black tomorrow and assemble later on. I'll glass at least one of the center sections tomorrow, too. Mounting the secondary and focuser is next. I have a feeling I'm going to want to use my 3" reflector as the guide scope, which means another EP is required.)
