I'm building a 12" (f5) truss dob atm .. lots of fun so far
I'm looking at the upper cage atm with regard to how much weight
is acceptable .. the ground board/box , alt bearings and mirror box are all a double laminate of 12mm ac ply.. yes its a little bulky but it is strong and still fairly light .. I could use the same for the top but am unsure if the little extra weight will be an issue .. at a guess the upper cage with focuser board will be a little over /under 4 pounds , with the secondary
and focuser still to be added to that .. to much ??
many thanks
