The Stuart Turner Beam Engine

The flywheel in the 4-jaw having it's outer surface
machined. The center hole has already
been bored and the front face cleaned up, all at the same setting so that
the surface runs true when finished.
It's very messy stuff cast iron, and I forgot
to cover the lathe bed so I had to spend the next half hour
cleaning all the abrasive grit off of it :-(
The flywheel measures 7" so it was easier to mount in the 8" 4-jaw rather than on the 11" Faceplate.

The finished flywheel and a couple of bearing blocks.
