I bought Hamilton Upshurs plans some time ago for his Hit-n-Miss Farm engine. At the time I was too new to the hobby as my machining skills were non-existent and my tooling inventory was slim, so the plan was to build a couple of smaller steam engines beforehand. Having done that, both my skills and tooling have progressed and my mill and lathe have been optimized for performance so now seems like a good time to get started. This will be my first IC engine and it should be fun as there is new territory for me to explore, like making my first gears. Those recent threads on gear cutting by Jerry and Brian will be coming in handy. I also get to make a spark plug, now thats something I never thought I would do. And some springs
.and a carburetor.
Oddly, there have been build threads for Upshurs started before on HMEM but they seem to have petered out after only a page or two. I do need to search more thoroughly as I might have missed something. If I Google Upshur there are a number of private sites documenting various incarnations of the same general design so those might be some help.
This first post is serving as a placeholder, as the actual build will get going a little later. Now Im in the material/information gathering stages and I need to finish my current Elmers engine (another two or three weeks for that video and final pics coming shortly). No doubt Ill be fishing this thread out from deep in the archives as I go. I estimate at the rate I work this might take me six months to complete. But that is six months closer to retirement. Yes, Im counting
I was leaning towards the version with the water tank over the cylinder but now more towards the air-cooled version with the neat-looking cooling fins. Those look like fun to machine.
I would like to buy the flywheels cast but so far havent found a source for that size which is 3.5 diameter and slightly over ½ wide. Bronze or CI doesnt matter. Anyone know of a source? Tried PM, they have one a little smaller.
If you havent seen this engine here it is, built out to different variations.
