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 using an
electric drill driving the crankshaft!

WOW! That's incredible. I'm sure most of us have dreamed of doing this at one time or another. Kudos to this gentleman for actually pulling it off.

It skips to much and i think it has some slop in the top end.
Just kidding. This thing is the exact opposite of an epic fail Dont know if the internet has came up with that word yet. When it does it should evolve from this thing

How the heck did he figure the timming out.

While is IS a work of art, it is not a Diesel, or even an internal combustion engine. It runs on compressed air. No spark (so timing is not an issue), no fuel (except compressed air).

And no issues with maintaining compression, lubrication, cooling, gaskets and tolerances (other than the parts have to be loose enough to move), etc. It's an impressive example of machine work, but not quite the miracle that some people may think it is.

Now if that was an actual, operating 4-stroke internal-combustion engine, that would be impressive! (but probably physically impossible at that scale).

The engines in the link I posted do run, even a micro jet engine for remote control planes.
