I’ve seen low D chanters for border pipes, and a chanter without keys that plays lower than that becomes impractical due to the large spacing of the holes. But with a coiled bore, an A 220 chanter, or lower (an A 110?) would be possible. Brass tubing would be the obvious material choice, but I can also imagine ways to fabricate it in wood, although not easily.
I might try making one in brass using a tubing bender. Has anyone considered this or encountered discussion about the possibility?
It certainly sounds like it would be a fun experiment!
But, your end result will probably not behave much like a border pipe chanter, because the coiled brass tubing will be roughly cylindrical, more like an SSP chanter.
…Unless, of course, you’re planning on making a tapered AND coiled chanter bore out of brass tubing. In that case, hats off to you!
well, here’s the thing. couple posts back someone said that unless you flare this spiral bore, this chanter will be a quiet one indeed. Theyre right. “Mr Curly” has a mounted transducer and is probly being run through a rackfull of Digital Signal Processors. Racketts, with their abnormally long, doubled back bores, IIRC-- are not particularly loud & (also iirc), they were designed to be played “In Consort”, SATB style, the shortest, highest rackett carrying the most important melodic voice. If you can make this idea work, then go for it! but i think your kinda gonna be fighting the laws of physics sooner or later with it, yaknowhaddimean?..
Brass will kink unless you fill it with a solder, bend it, then melt out the solder again.
here’s a good step by step on how to bend brass tubing http://www.youtube.com/watch?v=H7ySuxiUvAY
Although, for a rackett like chanter, construct it from rackett plans, usually made by drilling holes in a piece of hardwood.
Or for design purposes square tubing could be used. easily cut and soldered at the bends.
A cylindrical bore sounds at 4x it’s length so it’s def feasible. Good luck and keep us posted
There seems to be a bit of confusion about the classification.
The Hamon chanter appears to be roughly 25 inches long, provided it has a cylindrical bore (as it should have, being a smallpipe chanter) it would be in the tenor range. The same goes for the long chanter of the Cornish bagpipes.
The same length with a tapered bore (like a French Grande Bourbonnaise) is soprano.
For a true bass instrument you would need twice the length, 50 inches with a cylindrical bore. For contrabass add another 25 inches.
You rose quite admirably to that.
