My profile photo is of a nearly complete marine engine, taken about a year so far. Built from scratch from scavenged bits and bobs, had to buy a few things like nuts and bolts and pipe fittings. hope to run on steam someday, but for now it’s compressed air or demo running with the little electric motor. Jobs to do are the steam condenser, water and air pumps a final touch up of polish and paint, then move on to the next time consuming project (maybe a horizontal mill engine).
