Construction Making a gong stand - will aluminium tubing be strong enough?

Click For Summary
The discussion centers on building a portable gong stand using aluminum tubing, with concerns about the strength and stability of the chosen materials. The gong weighs 15 kg, and the proposed aluminum alloy is 6082, which some participants suggest may not be the best choice compared to the more common 6061T6. While aluminum is lightweight, there are recommendations to consider using steel for better stability and support, especially given the gong's value. Participants also discuss alternative materials like PVC for cost-effectiveness and ease of assembly. Ultimately, the goal is to create a sturdy yet portable stand that can safely support the expensive instrument.

I would like to keep the weight down on the stand for easier transportation.

This gong stand is unlikely to need to be portable

Anyway the OP hasn't been seen for over 3 years, this is a zombie thread unfortunately reawakened by irrelevant spam.

A well justified query but I am making some assumptions. The spec was 'transportable' and not 'portable'. The 'design sketch' implies a much stronger frame than would be portable anyway. Just how big would the gong be if it needs 120 cm width of stand? Several kg of gong if it's that sort of diameter and it would be swinging (6m of alloy tube at 1.6kg per metre, plus clamps and a Tam-Tam can be 30kg). A commercial Tam-Tam stand. This is more than a classic boarding house dinner gong, of course.

The op design has only right angled joints in it, which implies sheer brute strength of the bottom support brackets. We'd be talking six metres of scaffold pole. A few 60 degree angles in the design and some braces could reduce the frame's mass by a lot.

We'll never know the outcome of this.
