DJB whistles

[Keith S]

I've put a video of the whistle in the "videos" section. It sounds good, I think.

Here are some pictures of the finished product.





Obviously you can see the steam line (which I will replace with a black one when I can get some black tubing) but overall I think the installation is quite unobtrusive, especially the resonator, which is crammed between the regulator and the gas valve (handle supplied by Gremlin) and painted black. With the lid shut, it's not so easy to see at all.




And here it is on the outside:



Perhaps I've over-done it with the decorations on this engine, but it is the "shed pet" after all... Rule eight!!!

She looks good Keith, and personally I don't think you've overdone the decoration.

Lovley engine Can you go overboard on details on these things?

Then I have got my DJB whistle mounted. I didn't want to abandon the driver, so not much space in the cab. Got trouble with the fire being blown out, and the servos got soaked. The solution was to solder a small brass tube to the resonator around the drain hole and attach a plastic hose to lead water and steam out of the cab. Works very well.

I assume that using chain for the whistle rather then a servo rod works ok? It's a neat little idea, as you could blow the whistle manually as well as with the servo I'd guess.

I only took what I had, so not that much thought behind. Looks good and you can blow manually. The whistle lever tended to get stuck in open position, but a small drop of steam oil solved the problem.

I have a chain pull on my Ltd Jack and rod pull on my Silver Lady.

I use a spring in my whistle pull so that the valve is pulled wide open without anything getting strained.





Best wishes,

Well done – like the drain idea. I am currently fitting an R/C whistle to a Roundhouse Karen. Now there is loads of room here but it is not as easy as it first appears. I have the servo in the bunker with the servo arm poking out of the bunker door in the cab.
