Hello all, I've finally started a long-dormant project to build a
calliope-like instrument. Unfortunately, I don't have a decent wood
or metal shop, so I'm trying to do something fairly easy.
I've looked over the Dave Kerr's plans, and while the look very good,
they're a bit more involved than would fit my time frame. Did I
mention that I'd like to have this by the beginning of June 2003?
Building a windchest, keyboard, and air supply seems within reach.
This leaves whistles/pipes, which is where my knowledge fails. What
voices of flue pipes would work relatively well? I often see ranks of
used pipes on eBay and at other Internet sites for affordable prices,
although I suspect that they're voiced more quietly that this would
need. (The Tangley's played on .5-.75 psi or 14-18" wind. I think
that 7-10" would be adequate. Maybe less?)
The intended use is to accompany some English dancers in a parade.
The usual band just can't be heard over the amplified music on some
of the floats.
Any advice is appreciated.

[ Fairground organs and large band organs employ many, many ranks
[ of flue pipes to achieve huge sound volume. The air calliope
[ voiced for fairground ballyhoo employs a stopped flue pipe with
[ a full-circle wind sheet, and wind chest pressure approaching
[ 3 psi. Both organ types are easily overpowered by loudspeakers
[ with multi-kilowatt amplifiers behind them. If such a noisy
[ parade float is nearby, I doubt that one rank of ordinary organ
[ pipes could be heard at all by the dance troupe. (Maybe a steam
[ calliope? ;-) -- Robbie
