You build that engine? There are nuts on the steam engine I work on bigger than that thing.
But I'll bet it won't spin up like that!
My son and I designed and built that engine when he was in fifth grade. It was his science project. It was done over about five months and while I was guiding at pretty much every step he was involved in and understood all of it, including performing all of the machining
except for the flanged valve body. That setup was very flaky and potentially dangerous if it let loose. I wasn't even sure that I was going to get away with it. But I did.
I've seen a number of your posts about your work and it has to be one of the coolest jobs ever! My father was a King's Point graduate and still carried license for Liberty and Victory ships. He sailed on those at the very end of WW II and immediate post war as part of his internship. I heard many a story about those and finally got to take a short excursion aboard the John Brown out of Baltimore. Got to see the triple expansion engines under steam that I had heard so many stories about growing up.
