Jan 2021 Dowel Whistle Experiments

I donate woodworking items to a non-profit group that sells them as fund raisers.

For a future project, I could make 4 dowel whistles with a leather cord connecting them all together.

I have made various wood whistles using 1/4, 3/8, and 1/2" diameter holes.

Excel Spreadsheet

Using data from previous projects, I made up the spreadsheet shown above.

I made 4 whistles from 5/8" birch dowel, with 1/4" diameter holes.

I had only made 1 whistle with a 1/4 hole, so I was surprised at the results.  Only the shortest depth whistle would work!!  I could not get the other 3 depths to work at all !!

I decided to keep the shortest whistle, then drill the other 3 whistles with 3/8" diameter and the same depths.

Round #2 using 3/8" diameter with 5/8" dia dowel

I got all 3 of these whistles to work ok.

Future project

If I made new sets of 4 whistles, then.....

-use 3/4" dowel with 3/8" diameter holes

-or 3/4" dowel with 1/2" diameter holes

I like the 1/2" diameter holes on the square 4-tone train whistle, so maybe go with 1/2" versus 3/8" holes.

My grand-daughter liked the 2nd longest whistle using 5/8" dowel and 1/4" dia reed, 3.0 inches deep.
