Two cylinder vertical steam engine

[Aerofourcycle]

Felt the need to tinker in the garage and started a new engine. This is a hack together from a bunch of plans I have, including Kozo's Hysler cylinder an Internet two cylinder plan set and a book working steam engines. I think the hardest part will be the boiler. I'm using cast iron for the cylinder. I got the metal for making piston rings. For every part that is made, seems to need an adapter.
