Model Forum / General / Railroads / July 2005Seeking advice on Whistle Plans
Hello all, I am currently seeking plans or websites showing the construction of a whistle on any type of steam locomotive. I have the equipment and have been asked to attempt this. First thing is where or who do i obtain plans from? I have searched google but have not had much success. I have not had a task like this one offered to me before so I'd like any ideas or advice please. Cheers, Damien Before you start: Are you going to do a full size whistle or a model? Is it to used with steam or compressed air? The pitch of the whistle is a direct function of the size of the tube (diameter and length) The larger the tube the lower the pitch - refer to pipe organs for a classic demonstration of this. I don't know the engineering details but observation shows that whistles need to allow for the differences (of density?) between air and steam. The design you use must make allowances for whichever gas you use to blow it. If you're still interested contact me off-list for a scanned article I have to make a 'full size' steam powered whistle. I've not built it myself but the source is a good one.

I will contact you outside of the newsgroup thanks heaps. Damo > Before you start: > Are you going to do a full size whistle or a model?
