A guy on youTube channel Retro Steam Tech posted a video this morning of a Bottle opener that he made from a couple of spent C02 cylinders. I had commented to him that his video gave me an idea for spent cylinders, so I went down in the shop and made this;

It needs a proper steam whistle valve, but it sounds nice on compressed air. I would love to hear it on live steam.

I would love to hear it on live steam too

Looks great!
Nicely done Jim , lets give it a toot.
Bonjour Jim,
Bravo ! I can't wait to hear it also
That is a clever idea - did you used a 12 or
a 88 gramm co2 cartridge. Material is steel?
congrats - nice work, Arnold
Interesting. I was watching Alan's video last night and was thinking the exact same thing.
At the beginning of the video, I thought he was making a steam whistle.
Nice work Jim!
Have about 100 of those cylinders. I knew they'd come in handy for something.
I am going to do a YouTube short video tomorrow of the whistle. I will put it here when I publish it. I'll be blowing it on air.
Arnold, Material is steel (does anyone make these small cartridges from Brass? That would be awesome!) Not sure what size this is. It was actually a cylinder from my MicroNox torch.
Pretty easy to make. I actually made two yesterday but didn't like the 1st one. The thread for the valve is 1/4-40 ME thread. Could just as easily be 1/4-32. The hardest part was the little decorative acorn nut on the top.

I can't wait to see the video Jim!
Arnold,
Very cool. Sounds great on Steam. Looks like you built it almost exactly the same as Mine!

Bonjour Jom,
Well done and you should be able to adjust it by screwing and unscrewing the body of the whistle on its rod.
Bonjour Jim,
A whistle running on air is not obviously running on steam, to be tester with
