Re: Designing arms against buckling

Greg,

With regards to your first paragraph, the 2 x 2 without cutouts is more resistant to buckling than if you cut trusses in the 2x2.

Your second paragraph is the ticket. A lightweight core (even balsa or styrofoam) will definitely help the buckling scenario.
