@twofingers:
Michael, that was just a test to see if the tubes sound good together. Metal plates would have been more difficult to manufacture (above all: where would I have gotten the right formulas for calculating the frequencies?
).@phil99:
It's hard to see in the photos. The suspension points have been calculated and are unfortunately very far towards the center of the pipe. For the longest pipe, it's 76.2 mm. Unfortunately, this makes a triangular suspension very difficult to achieve.
I have found that, surprisingly, the tubes also sound good when they are suspended with bell wire (...is bell wire the correct term???). This allows them to swing in only one direction. I would like to try connecting them all together with a thread. That would then limit the remaining degree of freedom.
Electromagnets have been ordered—I'm curious to see if they are suitable:
Today I bought two MDF boards for the frame...
