Project - Mine Engine Part II

Part II - The Cylinder.


The Cylinder is a block of brass 25mm square by 35mm long. It has already been bored for the piston and the CNC Mill has been used to shape the outside.

In this set-up the cylinder port face has the steam and exhaust ports milled and the holes for the studs that hold the steam chest on have been center drilled.
