Very interesting. I'm impressed with the ingenuity that went into building it. Or should that be 'enginuity' ?
The chain drive cam shaft, the big end oiler, all of it is just too cool. I would have to guess that it uses a fuel/oil mix for cylinder and ring lube?
Thanks Dan.

I said the same thing, Intrepid, about the sound. Is beautiful.

Then asked if he had done an "indestructibles" when I meant to ask "instructables" Snork. I am gonna go with typo, speel check or "I meant to do that"

Tom, in the comments, some one asked and he said he mixed some 4 stroke oil in the gas. I was thinking some kinda McCoy oilier on the cam that could leach into the combustion chamber might be a thought? Then thought a fish bowl/bubble gum glass oil res.....


Dunno but that thing is just an uber cool little power plant
 
Very cool engine! I wish I could build something like that!
Too much machining for my skills!

The sound very much reminds me of an old fashioned stationary engine. When I was doing the small holder farming thing back in my 30s I owned a hopper cooled cast iron horizontal stationary engine. It wasn't very big and it had an open crankcase too with drip oilers on the bearings. I notice that the compression ratio was only 4:1 so it looks like it shares the same soft tuning as my old hopper cooled engine did. That would be one reason why it doesn'tt need a muffler to be quiet as my old engine never had one either and it chuffed away pleasantly to itself in exactly the same way.
 
I always find someone with talent like that always says it was nothing to build. It only took 2 or 3 weeks in my garage working part time using what I had lying around.

I couldn't build it if I had all year and a brass band playing!
