Default Rex Baldock Trike (Voigt pipes) HFN&RR 1961

I saw some nice Trike pictures in the forum here so I thought I post the articles that describe the construction dating no less than 50 years back in time

There are also other uses for this. I have seen quater wave pipes used as room resonance traps. The folding as described reduce the external length of the pipe as well as lower the Q.
