Hi
Great to hear the “voice” of the LTW guru himself on here!
Wednesday I built a D+ LTW from PVC hot water pipe. It just took one hit, and now I’m an addict! 
(I call it a “+” because it’s got seven holes so it can play a C with all holes closed). I’ve made it tunable and plan to build seven hole bodies for Eb, C and Bb as well. I’ll also make a standard 6 hole D body to compare how the two behave to try and figure out whether the seven hole configuration has any disadvantages.
The finished instrument is well beyond my expectations. Pure and sweet and in tune with itself and the world. I keep picking it up to play it again - and again. It’s a very special feeling to play the first instrument I built myself. It’s hard to be objective about this, but I’m pretty sure that if I walked into a music store and found a whistle that sounded and played like this one within a reasonable price range, I would buy it.
The only negative would be that I would have liked a little more chiff. I’m not sure how to accomplish that. The hot water pipe is approximately 11 mm inside dia with 2mm wall thickness, so I had to sand it down a bit to each side of the airway as it sounded a bit breathy and needed too much air with the 2mm high airway. That seemed as good a way as any of dealing with the wall thickness issue. Of course it has to be done in stages as it’s difficult to put back what I remove…
The really nice thing is the hot water pipe is cream in colour and when matted down with 400 paper to make the surface dull it could actually pass for bone at a distance. I’m thinking of telling a story as I play it of how I met this old man in Africa who was making these wonderful instruments of Antilope bones. Then before the last number, I’ll let the cat out of the bag and admit it’s PVC waterpipe. There might be an opportunity on Sunday… I’ll look for some electrical conduit tomorrow which has larger inside dia and thinner walls.
A question you might be able to answer. On the Low Tech Whistle site, you say the airway should be no higher than 1.7 mm to avoid the whistle becoming too breathy and that was my experience too. I assume you were talking of Soprano D whistles and the height would be different for a low D, which may be my next project? Any idea what range to look for on the airway dimensions on a low D? Also, there is very little in the article about the actual shape of the lip, except that it should not be too sharp as that makes the whistle sound like a recorder.
After the Low D, I think I’ll start on my sister’s Christmas present. She lives in Norway and has recently taken up the whistle and as far as I know, all she’s got is a crummy Generation. (she’s a professional opera singer and music teacher). It would be fun to send her a home made soprano whistle set with Bb, C, D and Eb bodies.
Well, this means I’ll probably skip buying the Syn set with four bodies I was considering, but I’m still ordering a Dixon Trad. Got to have something to aspire to…
SOMEBODY STOP ME!
