Lister D Compressed Air Engine
cfellows:
My Bessemer Oil Field engine is taking a lot of design time and not affording me much shop time. At the moment, I'm waiting on a 1/16" NPT tap and die set, so I decided to start on another engine that would let me make some chips while I'm not able to work on the Bessemer.
This is a compressed air powered engine, 3/4" bore and 3/4" stroke. It will be as close to lookin like a Lister D engine as I can get. I've always had a fondness for the Lister D because of it's simple, utilitarian design. It will be a 4 stroke engine and will use my slave exhaust valve with a cam actuated inlet valve. Here is a picture of a full size model which has a 3" bore and 3" stoke.
Here are some pictures of the block that I've started...
The block is made from 2" square aluminum bar stock and is about 3.625" tall. It will have some further shaping done on the outside once I finish all the internal machine work.

I will be watching with interest.
I have one of the big brothers to the D, a TVO engine sitting in the stable with a very pretty sludge pump with over head rocking arms attached :D.
