I see it, about 18:36, nice bottle engine. His engine at the beginning of the video is very nice too, and he really got the balance designed correctly. I can't tell if he made that engine or not, but the home-built ones I have seen would jump off the table if run at that speed, and his does not; very impressive counterbalance design. Thanks for posting; lots of other nice engines in the video too.
He found most of that engine. He made the missing crank and some other parts. it's victorian I believe. Cool engine.
I tried listening to him talk about making the crankshaft, but it is difficult for me to make out what he is saying. I can pick up about every third word; wish he had subtitles.
It comes with practice Pat. If he was scottish, I'd be screwed. It's those Ayes, nays, cannae and wees that send me for a loop. If you listen close, John farts constantly on his videos. Its hilarious. Anyone know the story to what's up with his left eye?
