Steam Whistle by Mark Guinan ( in U.K. )
The plans are posted after many requests. The jpeg file should be the most universally readable,
but lacks definition, the pdf is better but needs acrobat reader. Obviously the dwg file needs Autocad LT or better to read.
Top three drawings are of my original sample, bottom views are of the one i made. There are some missing dimensions and at least one fit error.
I claim no rights to the drawing or design. The original model was made by a Mr. Alan Owen, presumably either from some loco plans or copied from another.
If you reproduce these drawings for others I would appreciate it if you keep the references to Alan and Ralph Mitchell.
Have fun. Be cautious with the use of compressed air / steam. Ear protection may be required !
