Wooden Train Whistle





Introduction: Wooden Train Whistle

About: I am a high school design and technology teacher and I love making things, especially if it involves using recycled materials. I use instructables all the time and find them inspiring, motivating, useful, an...

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!

Nice project, thanks for sharing!

i might try this out with bamboo...

So simple - thank you. If you want different tones then you can change the depth of the drilled hole in step 2: shallower will give a higher note. Alternatively, drill right through and use a longer piece of your dowel, slide it in from the other end to the air hole and adjust the note by changing how far its pushed in.

Thanks for the comment, I haven't experimented with tones, I will give it a go.

Great suggestion, thanks

I've been looking for a pattern for a train whistle and this is the BEST one. Thanks for sharing.

Hi, thanks for sharing the memory, I'm going to look out for small hollow branches!

be carefull their is a hollow weed called hogweed that is what looks good but it can cause skin burns and blindness it grows most places it has a big flower like queenann lace but it grows to 8' or taller please look out for this......frank

Thanks for the heads up


Hi Frank, I think bamboo will be a good choice for this type of project. Michaels (or any art supply store) sells bamboo. I have collected a piece from my friend. I am going to try it out. Thanks for the nice post Ms Wild.

Great idea! Have you ever heard of making a whistle with more than one tone? Maybe 2 or 3 or 4? I read about one a long time ago, but of course, forgot where!

Good job!
