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.
