Hi folks. Thought you might be interested in seeing how my Upshur hit-and-miss runs with different governor weights and springs. Nothing much new here. I just wanted to look at light weights and heavy weights, weak springs and strong springs, and see how different combinations affected how my...

It's been around for a while, but still one of my favorites. http://www.youtube.com/watch?v=ddVZOK_9UUI Here's hoping everybody here is as blessed as I am this Christmas. Rudy

Don't forget that along with all its other uses in the shop, aluminum foil takes good impressions of flat parts. The way I do it is to lay a piece of craft paper down under the foil as a thin cushion (a paper towel would also work), put the part on the foil under a piece of scrap wood and give...

When I'm drilling a hole with my mini-lathe, I like to apply a little pressure on the tailstock quill lock to keep the quill more stable while I'm advancing or retracting the drill. But maintaining an even pressure on my machine was something of an art, because the friction on the quill changed...

After I finished the spindle-column alignment on my Harbor Freight mini-mill (http://www.homemodelenginemachinist.com/index.php?topic=6007.0), I still didn't get a good tram in the Y-axis.

After reading an earlier thread about off-center drilled holes HERE, I checked my Harbor Freight mini-mill and found that the spindle was not in alignment with the column, apparently not uncommon with the Sieg X2 machines. From what I've read, the only practical way to align the spindle and...

She looks better now that she's cleaned up and uncluttered. I made the spark plug from a Fox glow plug body and a sample of Corian countertop I got from a local home improvement store. It worked OK, but I broke off the bottom electrode trying to adjust the gap (note to myself -- those plugs...

Below is a short video of my upshur hit-and-miss running. She gets just barely warm after running for several minutes on Coleman camp fuel mixed with a little WD-40 for lubrication. Haven't tried an endurance run yet. http://www.youtube.com/watch?v=SiDlZ9rubgg I've also included a longer...

Pictures of my first engine, a hit-and-miss farm engine built from plans by the late Hamilton Upshur. 0.75" bore, 1.0" stroke, 3.5" flywheels (all measurements approximate; after all, this was my first engine) ;D. It's sitting on it's test bed here, eventually I want to make a nice wooden base...
