I am thinking about building a steam engine without using brass. I also cannot locate a big enough piece of cast iron for the cylinder but can find smaller pieces for the piston and D-valve if needed. Plenty of SS for rods and shafts and flat CRS of 1/4" or less.
Now my question is if I use Aluminum for the cylinder with no liner, what would be best for piston, CI or CRS or 12L14 steel? And is it possible to use a CI D-valve against an aluminum face. I could make a CRS face plate for the valve but I'm just asking.
For other wear points like con rod ends and crankshaft bearing, I'm thinking CI. I'm not sure which way to go with the eccentric. I could go with a CI eccentric strap, but would CI, 12L14, or aluminum be best for the eccentric?
For the cross head, I'm thinking a combination of CI crosshead on SS or drill rod but other suggestions would be welcome.
Cylinder dimensions of .625" bore x 1.25" stroke.
I have not yet decided on the configuration but probably horizontal mill engine.
