Crosshead
The crosshead guides on the 110 are pretty simple, except that the
sides are supposed to be angled inward toward the top. It took an odd

it worked out okay. Still, I'll probably do it differently next time
around.

machine. They're thin and were chilled almost all the way through, so
they were hard to cut.

Rings
I made the piston rings from cast iron bar stock.

Miscellaneous
Here are groups of engine parts in an almost-finished state. The
pictures were taken shortly before trial assembly.
