A Beautiful Steam Engine with Construction Details

John Bentley made this beautiful half-scale vertical steam engine.  He also did a great job of documenting most of the process on his construction page.  I was surprised to see how he fabricated the rim for the 7½-inch diameter flywheel out of a 1½-inch diameter drive shaft salvaged from a boat.

33. Space is a completely unforgiving environment. If you screw up the engineering, somebody dies (and there's no partial credit because most of the analysis was right...)”
