Scratch-Built Vertical
« on: November 05, 2020, 06:53:21 pm »
I found this engine a while ago, and I've decided that it must be scratch-built, as I've never seen one like it and I can't detect evidence of castings. The pictures don't include anything to show scale, but it's more than twice the size of a Stuart 10V.

It's very well made, if you excuse the slotted screws and funny lock nuts, which I can replace, and it looks like it was never really run. When I tried it on air, though, there was definitely something binding, so I loosened the main bearing caps just a tad, and that helped immensely; I think that just a couple of hours of running in will cure things.

I'm out of action with back trouble right now, but when I get back on my feet I'll try to make a video.

The frame does not look like any of the Stuart V frames I have seen, but the flywheel could be from one of the larger Stuarts, or it could be from elsewhere.
Some folks do make their own flywheels in iron castings, but it is rare.

I prefer custom made fasteners to give the period look, but everyone has their preference.

Nice looking engine.
