MIke M., I believe your D&M SP 6 is a normal single bell chime, if it is then 1 circular slit properly aligned (OD of slit = to ID of bell) is what it should...
I bleieve that the only reason that bundled tube whistles ever worked at all with out significantly over blowing the longer chambers is what Peter and Richard...
You'll find what you're looking for in the files "whisparts.jpg" and "definitions.rtf". A circular slit is just what you want for most single bell chime...
Dave Wolf is working on a version of my open top bearded whistle design in "specialwhis.jpg". The whistle is of 6:1 scale rather than 3:1, since open top...
I was able to open Excel with free Microsoft Excel Viewer but it won't let me enter values so it can do the calculations for the other parameters. How can I...
The good news is that you got to see it using the free Excel Viewer. The bad news is that you need Excel itself to use it interactively. I have to run the...
Richard, Thanks for the info. I guess What I need to do is tell you guys what I'm trying to build. It's basically going to be the "Hooter" on the N&W Class A...
I am without access to the Excel spreadsheets until Monday, but a hooter is one of the simplest of all whistle designs to build. I believe the diameter of the...
Gentlemen, As you may know, my son had the honor of representing his school and the county of San Bernardino at the California science competition. His...
I'm glad to hear that your son made it to the state finals. That is quite an honor in itself. I'm also glad that his project got noticed and generated public...

I believe that is how the formula has to be entered in Microsoft Excel. The formula translates to: Slit Area = (languid OD + bowl ID)/2 pi times the slit width...
Pardon this post from a group newbie, but I have been searching for a brass whistle, any type of whistle, engraved "Gift of Southern Railway". Can anyone point...
Oh I forgot my source is the air compressor at work ( auto shop ) which is 150 psi. ... I'll ... is ... making ... is ... Monday. ... itself, ... fully ... the...
Monday it will be a simple matter of opening the file "whistle scale vs presure", plugging in 150 for the pressure and 2.45 for the scale. The spreadsheet will...
We are looking for a blueprint or a copy of one or a dimensioned drawing of a Hancock Air Whistle so that we can build our own model of one Thanks G Life...
George, there are dimensioned drawings in Horn and Whistle magazine No. 107, and also at this site accessed from Google Patent Search for Patent No. 2784693 ...
Richard, Thanks for helping with the parameters. I said that my shop compressor is 150psi. My question now is, would less pressure give me the same amount of...
The SPL of a whistle is all in the flow rate-not just the pressure. If the flow rate can be maintained at a lower pressure, the whistle will be just as...
Assuming that the N&W hooter uses a 5" x 11" bell, here are your parameters. I asked if anyone knew differently and got no responses, so I assume the...
Jamie, The asterisk (*) is the multiplication sign or times. The carrot(^) is power or in this case (R^2)- radius squared. Sorry for the confusion, it's hard...

I actually got 262.9 Hz for air. I mistakenly wrote it down as 262.4 Hz, probably since it was 309.4 on steam. A difference of 1/2 a Hz isn't much of an error...
