[@yagwaw]

Very nice work! How do you manage to work with cast iron and keep your fingers absolutely clean? I want to know this trick!

[@bambukouk]

So the crank has no bearings ? And its just the close tolerance that forms a seal between the crank and the case ?

[@JellyFishMachine]

Yes, no bearings for the crank, it runs right in the aluminum case. the seal is from the high amounts of castor oil in the fuel, filling the small gap between the crank and crankcase.

[@TheXSpitfire]

@@JellyFishMachine Okay that makes sense. I made a 2 stroke engine too, very crude, but it ran a few seconds. Enjoyed your series.

It's much like what Cox engines did for the crank bearing, just used the aluminum of the case as the bearing. It was very practical back when they were popular and plentiful. You could buy a Cox .049 'Baby Bee' for $3.95 in the hobby and toy dept. at retailers, sold in small blister packs and backed with card stock. Pretty sure the Cox crankcases were made from extruded stock, very simple machining to finish.
