Low Whistle Parts

Block insert and outer shroud need to make a Low-D PVC Tinwhistle/Pennywhistle. Low D is the first D note above Middle C on a piano Requires 24" of 3/4" PVC pipe, SDR21 grade (thin wall, do not use Sched 40) Go easy on the print speed, otherwise it will deform. Get some very thin (watery) superglue for this. Print Settings Printer Brand: RepRap Printer: Prusa i3 custom Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.1 Infill: 25% Notes: Go easy on printing speed Post-Printing Assembling a pennywhistle Cut 3/4" PVC pipe to approx 24 inches long. (note, to Europeans and those not familiar with PVC, it's called 3/4" but there is nothing there that is actually 3/4" diameter). Using a hacksaw, cut out a 1/2" by 1.43" rectangular slot on one end of the PVC pipe. Using a file, file out a ramp for the windway as shown in the photos. Clean up the pieces from the printer before installing. Slide the insert with it's 1/2" notch in alignment with the 1/2" notch. Then slide the outer shroud piece over the PVC pipe and also align the 1/2" notch. The diagonal portion should face away from the pipe. Line of the lips of the two pieces in the airway hole. Try to get a sound out of it, when you are happy with the sound, secure the two pieces using super glue. Then using a tuner, see what note you get. You'll need to trim away from the bottom until you get a well tuned Low-D note. Then it's time to make tone holes: I'm giving the diameter of the holes in inches and the position from the bottom to the center of each hole in inches. Note, you might have to tweak the holes diameter a little after drilling and also clean up the plastic bits on the other side of the hole. For Low-D: 15/64" 101mm 7/16" 146mm 3/8" 163mm 5/16" 222mm 3/8" 256mm 3/8" 295mm For other keys with this design, consult "Low Whistle Makers Anthology". How I Designed This History I originally design the PVC whistle using PVC fittings and a block of acetal cut out on the lathe. I've been making whistles since 1998. The age of 3D printers has made the most difficult part of the pennywhistle easy to make. The shapes are made using OpenSCAD, being a computer programmer I find OpenSCAD very appealing.
