Default Re: Something new and kinda sorta 100 years old looking

NOTE TO SELF: Steam engine with a wet crank in a closed crankcase: Really bad idea.

Oh well, it's always nice to learn things.

So, took it all apart and cleaned out the oil foam pudding gunk. Next, drilled a 3/8" hole 1/2" up the side of the cylinder from where it meets the case and a 1/2" hole at the case seam in front and above the mount. I made a nice clean hole into the cylinder and then polished the edges with some 1500 grit emery cloth. The cylinder hole is at the lowest point in the travel of the wrist pin. So the wrist pin can be oiled from there and the rod journal can be oiled from the hole in the case. Rubber plugs might be all these access ports need to keep out dirt. As stated before, the side shaft bearings will be oiled with a syringe through the top of the seal. So manually oiling the bearings will be part of the maintenance ritual. The cylinder will be oiled by steam oil in the feed line.
