View Full Version : Tiniest engine

It isn't CNC technology; this guy made everything at home on his lathe and drill press. Took 1220 hours (year and a half?) to make the 261 pieces.
Note the end-loaded crankshaft into the block (like an Offy), 12 individual cyl heads, TINY rods and pistons, dual "underhead" cams with push-rods to rockers in the heads.
And, he did break-in using an electric drill driving the crankshaft!
Even if you're not an engineer, you'll love this

I loved your little tiny engine, and I am just as enthusiastic about this monster! This is the crankshaft for a ship engine; a diesel. Almost all ships are powered by monster diesels these days. Steam is hardly ever used unless the heat is nuclear generated.
The above is a Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine, and is the most powerful and most efficient prime-mover in the world today.
Yeah. Two stroke. Locomotives are two stroke, too. That's because in those applications the engine almost never changes speed. One speed. For days, and days, and days.

My uncle was an engineer and as a hobby had a lathe and made a pair of wooden spinning wheel bookends for each of his brothers. After my father died, my sis took one and I got the other. It's so valuable to me, lovingly made, great detail, plus it has a tiny plaque with my dad's name, Pete, on it. No matter where I move, it always goes with me.
My uncle Chris was my favorite uncle who travelled all over the world and would bring little silly things like souvenir silver spoons from Europe and a beautiful silk handkerchief from the Netherlands. I always loved to go to their house.
He worked for a firm in St Louis that made large engines (he designed many of them).
