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

Click For Summary
SUMMARY

The discussion centers on constructing a gong stand using aluminum tubing, specifically alloy 6082, with concerns about its strength and stability. The gong measures 38 inches in diameter and weighs 15 kg, prompting inquiries about the adequacy of 33mm external diameter tubing with a 3mm wall thickness. Participants recommend considering alternative alloys like 6061T6 for better availability and strength, while some suggest using steel for enhanced stability. The conversation highlights the importance of balancing portability with structural integrity in the design of the stand.

PREREQUISITES
  • Understanding of aluminum alloys, specifically 6082 and 6061T6.
  • Knowledge of tube clamps and their applications in construction.
  • Familiarity with basic structural engineering principles related to weight and stability.
  • Experience with DIY projects involving metal fabrication.
NEXT STEPS
  • Research the properties and applications of aluminum alloys 6061T6 and 6082.
  • Explore the use of steel tubing for constructing portable structures.
  • Investigate alternative materials like PVC for lightweight construction.
  • Learn about the design principles for creating stable and portable stands.
USEFUL FOR

DIY enthusiasts, musicians, and fabricators looking to create custom stands for instruments, particularly those interested in balancing portability with structural integrity.

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.
