We CNC’ers don’t know how easy we’ve got it, but one look at this quarter scale V8 told me that builder Keith5700 from Home Model Engine Machinist is nothing short of an amazing craftsman.  HMEM is one of my favorite hobby machining boards as it is filled not only with amazing craftsmanship but also genuinely nice people.  We’ve all suffered at the hands of some Internet Troll on one of the big boards or other, but HMEM doesn’t tolerate that sort of thing.  They just want to be a big group of friends having fun building model engines.  And build them they do.  Here’s a video of the engine running:


Keith built it on “an old lathe and Bridgeport manual mill.”  He says it took about 2500 hours to build, 500 of which were various experiments that didn’t work out.  If you’d like to know how he did it., the build is fully documented with photos on the HMEM thread.
