My whistle could sound like a wet fart when running on steam!

Hopefully not though as the whistle design isfrom the original plans and there have been hundreds of this type built.

The next step was to make a Goodall valve, I had been borrowing one from the large De Winton. I took down the dimensions. I'm not using an o-ring.

I reused a boiler pressure test blanking off plug, drilled it through for 3/16" K&S brass rod and silver brazed it in.

Great job on the Goodall valve Dave. It looks a big improvement on the original dare I say.

Have you tried your whistle yet mate....let's hear it please... :thumbup:

The valve is very similar to the Roundhouse type.

Here we go Rod



It wouldn't work on steam yesterday. So today I had a brainwave, try it on compressed air (car tyre) and at a low rate it sounded fine then and then rapidly blew out as the supply was opened up. Ah ha, I needed a restrictor. A piece of 1/16th tube was placed inside the whistle's 3/32" inlet tube and Hey Presto! It worked at all flow rates. The steam test has the restrictor fitted. The car tyre is at about boiler pressure - 30 psi, it just needs pumping up afterwards :thumbup:

I think you've cracked it there, Dave. Sounds really good with that slightly breatheless effect. Well done.

Good work on the Goodall valve and the Whistle. More noise from less steam seems counter-intuitive clever of you to work that out.

Bang on Dave, I like how the whistle sound gradually changes when the condensate clears.

Thank you, lads.

A rolling road will be needed for the next round of testing. It was very pleasing, I had all the materials in stock. This spacing suits nearly all of my locos except the first one, and it fouls the meths tank a bit. I'm thinking of adding an extra set of holes for closer spacing for that loco.

Had a very nice test of Loco #1 on the rolling road today. It's been a while since this loco last ran

Best wishes,
Dave
