This restoration is on a 1920s Orr & Sembower vertical steam engine. In Part 2, I remake all the missing and broken parts as well as slowly reassemble the entire tool. I decided to make a few sensual upgrades as well. The missing bronze shoes on the crosshead were complicated enough to remake that I decided to call for help to @Keith Rucker - VintageMachinery.org and @Windy Hill Foundry. My machining equipment and personal skill were pushed to the maximum for this restoration, but I think it all turned out well enough to function. Making a new piston and piston rings was particularly challenging but was very rewarding. I really want to run this steam engine on actual steam instead of my air compressor, but I do not have a steam boiler. Maybe I'll restore one in the future for this use. The steam engine seemed to run just fine on 14CFM @ 90 PSI and lower.
