You've picked a challenge but seem to be moving right along.
Have you had much machining experience?
I've only made one complete Elmer Verburg Mine engine. It looked good but ran poorly so now I don't dare to make two great casting kits I have.
Shame since both are beam engines (Mary and ME Beam) and I've all ways wanted a nice beam engine.
I have had a little bit of machining experience.
Previously i have purchased botched Stuarts and completed.
A write up here for a Stuart beam .
