Hope all who asked for the whiste plans have got them OK, certainly had enough requests ! Just to clarify how this thing works ( I think ! ), Air/steam blows through an anular orifice in line with the base of a thin wall bell or chime, making it ring or hoot. The tone obviously depends on the dimensions of the chime- larger will lower the tone. There are two adjustments in my one- the base parts screw in and out to adjust the air orifice, but if you have the outer and inner parts level with each other that should be about right. The chime screws up and down in relation to the orifice, not to sure of the physics of it, but this needs to be fiddled with to get the loudest volume-guess this has to do with the resonance. I believe there are some of these whistles with a loose plate or little propellor type thing inside the chime that moves up and down as the air is supplied giving an osscilating tone, that would be a novelty ! but not had time to play with that, wife complained enough about the noise last time ! Like to hear if anyone tries this with steam, does it sound different than with air? All the drawings I,ve sent off to you all are autocad LT ones, if anybody wants another format let me know. All dimensions are metric (mm) by the way. Cheers, Mark
