Dear Eric
Yes - I'm wholly with you in making up devices out of obtainable materials rather than simply for paying for the "name" of a manufactured object . . . and when people apply the adjective "mad" to myself, I take it as a great compliment. Microwaves and acoustics have waveguides in common . . . and many people do not expand thoughts sideways as the 18th century polymaths quite rightly did . . .
I think that there was a travelling organ of the sort you intend built in the 1920s which filled two lorries. I'll try to find details in due course. This sort of project is so worthwhile in bringing the organ to the people . . .
Best wishes
David P
