Position of Safety Valves

Tetramachine,

I've been toying with that idea. Hardest part is getting the right number of turns so everything lines up coming out of the boiler.

If it doesn’t line up correctly, run a tap a little deeper into the boiler.

Bigboys are angled. Drill and tap it where you want it or weld in a half coupling if the shell is less than a quarter inch.

I always thought they were vertical too but the picture in Fitt's book shows them line horizontally. One in the middle. straight up and one on either side at a slight angle due to the curve of the boiler.
