Here are a couple of pictures of my Upshur farm engine that I would like to have added to the Work in Progress section.  I hope to have the engine running by spring.  I have made a few minor changes to the engine but it follows pretty closely to the original design.

It has a 3/4" bore, a 1" stroke, and a lapped cast iron piston and sleeve.  Instead of a water hopper, I think I am going to fabricate a simple thermosyhon cooling system.
