Hey gang,
Concerning Newtonian tubes, be it sonotube, aluminum, or whatever.
How much material can be removed by drilling holes or cutting a lattice pattern in the tube before structural integrity is compromised or flex is induced.
And, any ideas as to what pattern would be best?
I'm just daydreaming about lightweight tubes.
