Bruce MacBeth Engine Plans

[cfellows]

Got my latest Home Shop Machinist today and was pleasantly surprised to find the first of a series of build articles for the Bruce MacBeth, 4-cylinder power plant engine. It's a beautiful engine and done without castings, except for the flywheels. I could also see my self building a 3 cylinder version of this engine, like the Fairbanks Morse Model we see floating around from time to time.

Pay particular attention to the crankshaft construction. It looks like a fairly easy way to make multicylinder crankshafts with ball bearing mains.
