cutaway engineWe’ve had some inquiries about the cutaway engine we bring with us to shows and Maker Faires, and I’ve always wanted to make more. I cut the first one away with a hacksaw and lots of elbow grease, but I’ve since streamlined the process. The new cutaway engines feature a precision milled engine block and cylinder head, revealing the engine internals. The crankshaft, camshaft, balance shaft, piston, pushrods, and valves all work with a turn of the crank. The starter motor, flywheel/ring gear, and carburetor with throttle and choke butterfly valves are also present, so this is as close to a working engine as you can get… except for the gaping hole in the side! The cover plate is made from laser cut acrylic, and the hand crank is zinc-plated steel for years of reliable service. Cutaway engines are great as both teaching tools and conversation pieces! See the Cutaway Engine product page for details.
