If your team has access to a wood shop (table saw, planer, joiner, etc.) it is easy to make tight fitting wooden plugs, one to three inches long, to go inside rectangular or square aluminum tubes. This makes it easier to join tubes, using gussets, through-bolts, pivot bushings, etc., without crushing them when you tighten the fasteners.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
