The building of a Stuart V10 & D10 Engines
The Boxbed
I have decided to follow the book "Building a Vertical Steam Engine" and it suggest starting the construction with the boxbed. The boxbed is the very bottom casting of the engine and is the part which would be connected to for instance a wooden base board. The book recommends that the bottom of the casting is machined first and that this only need a very slight skim over. A check is made as to the amount that can be removed in the machining.
The casting should be cleaned up of any protruding blemishes to the top surface and then held in a 4 jaw chuck fairly centrally with the top surface bedded tight to the steps in the jaws to ensure that the surface is at right angles to the axis of the lathe.
An alternative as seen on YouTube is to machine the top and bottom in the milling machine.
I started in the workshop with the basic filing to clean up the casting of the base.
