I'm starting a model loco project, live steam of course, and want to set it up with a Goodall valve. I understand the principle of how it works but am wondering if anyone has dimensions or building info. I want to make it to fit a 1/4"-40 bush. My main concern is the taper of the nozzle and valve. Any insight on this would be apprecited.
