Don, Melanie received her horn and heart and everything looks like it will fit. When you epoxied the sounder to the horn cover did you remove the black cover from the sounder? It seems to snap on and off with ease. I will probably be making my own rear bracket to help stabilize the horn, as the inner pocket of the heart will require a substantial puddle of epoxy to attach to the sounder. Thanks, Roger
Left the bellows complete with the exception of the part of its body that held the compressor. If pics really are worth more than words will see if an illustration might help. First image here is compressor separated from the body with the body still intact.
Longitudinal view of the body with the compressor removed. Hole you see is the inlet for the pressurized air stream.
Same body after it had been visited by Dr. Dremel. How it might need to be cut to fit in a different housing of course might vary. But in this particular housings the depths were fortunately similar as were the widths. It wasn't a bad fit after nearly everything possible was removed from the body of the horn.
Sounder as it still resides in the horn cover. Brass fittings in the pressure inlet hole. 3/8" fuel line used to carry air from the compressor to the horn.
