Nigel Perry asks whether it is possible to make trumpet pipes with
harmonium reeds.  Being rather naive, but curious, about the same
subject, I have been trying to do that.

I have been using recycled reed organ reeds from circa 1960 organs
purchased on eBay.  While the reeds are designed to operate on vacuum,
I have devised a mounting which allows them to sound on pressure.

I have made some wood trumpet horns in the general style described
on the Wurlitzer plans I have.  I have not been able to get a good
resonance when combining reeds and horns.  In the few cases where
resonance has occurred, the horns pull the reeds off frequency.

I am working toward an original design, not a Wurlitzer copy, so
I am considering working up a soft free reed voice and constructing
traditional shallot drivers for my louder trumpet rank.
