Rooster—I have certainly been in the smokebox, but I doubt it was me in that photo. I Think I know the photo…I am not sure who that was.
well here are some more photos
One of my interesting jobs was machining the new whistle
That is me holding the whistle. It was designed based on what we know about whistle design and what our engine had in its lifetime. this is a “hooter” single note whistle which was what the Portland Sompany supplied in 1891.
this is the assembled whistle. the slot around the base is where a wall of steam comes out which sets the air in the “bell” to resonating which makes the sound.
the bit on the table is the valve spool the tapered head on the right side is what closes off the steam. The fat part of the web will be milled to accept the whistle lever which pulls the valve spool away from the opening allowing steam to flow.
