AN OPERATIONAL V-12 DIESEL ENGINE THAT FITS IN THE PALM OF YOUR HAND.
This is not CNC technology; this guy made everything at home on
his lathe and drill press. Took 1220 hours (a year and a half?) to
make the 261 pieces. Note the end-loaded crankshaft into the block
(like an Offy), 12 individual cylinder heads, TINY rods and pistons,
dual "underhead" cams with pushrods to rockers in the heads. And, he
did break-in runs using an electric drill driving the crankshaft.
The world's tiniest V12 engine.
