My New Twin Cylinder Slide Valve Steam Engine - Bottom Half!

This is the engine I had so much trouble with, trying to make a truly accurate and concentric twin cylinder crankshaft! The bottom half is now finished, and the cylinders, pistons and valve have yet to be made. These components will be the subject of an actual step-by-step machining video (IF I manage to make them properly, and don't make any more mistakes, and IF the engine runs properly!) Don't hold your breath! Wish me luck!
