Introduction: Wooden Train Whistle

By

This is a small wooden whistle that is quick to make and sounds great.

Material used in this example is 20 mm x 20 mm x 150 mm pine and 9.5 mm dowel

This plan is based on a similar one by dirtbike98

Step 1: Mark the Centre

Mark the centre of one end.

Draw a line from corner to corner.

Step 2: Drill Hole

Clamp your material in the jig under the drill.
Check the drill bit is lined up to drill down the middle.
Drill down as far as you can.

Step 3: Mark Out the Air Hole

Follow the measurements on the plan to mark out the air hole.

Step 4: Cut the Air Hole

First make the straight cut by clamping your work in a vice

Step 5: Angled Air Hole Cut

Take your time to saw the second angled cut
You can hold the base in a vice and hold the saw on an angle to cut.


Or if that's not working for you use a jig to guide the saw.

Sand the air hole edges smooth with sand paper

Step 6: Prepare Dowel

Cut a 20 mm section of dowel, this will be fitted into the end of your whistle.
Sand a flat face onto to dowel.
This flat face will sit up so the air can be blown over it and exit through the air hole.

Step 7: Project Complete

Your whistle may need a bit of fine tuning now.

You can adjust the sound it makes by flattening the dowel some more, smoothing the air hole edges, pushing the dowel in further or removing it a bit and making the hole deeper

Good luck!
