truss poles for 12" Dob: what size works best?
Found a local supplier for aluminium tubing to use for a 12" truss Dob (thanks Vermin!). For those who have done this before, what size tubes do you recommend for the truss poles? These are the sizes available from the supplier:
Outer diameter : wall thickness (in mm)
25 : 1.6
25 : 3.0
32 : 1.6
32 : 3.0
