Bench! that was the word that puzzled me. For some reason I kept hearing "b*tch".. Dear me.
Metal benches are real treasures... Hard to get these days. Of course you can build your own, but one always finds an excuse not to... :-)
Great engine anyways, and I for one don't mind the rattling.

I have no idea how much the reciprocating parts weigh. When I designed the crankshaft, I used steel I had on hand and made the counterweights as large as the material allowed.
It must be balanced pretty well because the only shaking is horizontal, due to the reciprocation, unavoidable in a one-cylinder engine without counterbalancing shaft.
Thank you for your comment!

Your wright low reving engines are more intrasting to watch.

The Hvid fuel system isn't conducive to high revs. The system on this engine starts falling apart at about 1100 RPM.
In any case, if it ran too fast, it wouldn't be as interesting to watch.

It's a very nice looking engine, runs well too. I like it.
However, I'm puzzled when it comes to 0:57 - the commentary, to be exact - what is causing the rattling?

@bladerizer
The rattling is caused by the vibration of the engine. The "bench" is what's left of a really old 10MB H-P hard drive. Made of metal, there are several joints that are loose. I may fix it one of these days ....... Maybe. :-)
Thanks for your comment.

seems to run well. i like low idling engines.

It runs slowly only because of the heavy flywheels and long stroke. If I try to run it at up to about 1,200 RPM, the fuel system begins to not be able to keep up. Sort of self-limiting.
Thanks for your comment.

how much does the rod and piton weigh? do you have plan on balancing it better?

@turtlemann14
Sorry I'm late with the answer to your question! Having apologized, I don't really have any idea of how much the piston and rod weigh. Rod is of steel and piston is of cast iron so they aren't light although the rod isn't as heavy as it looks due to the fact that it is hollow (pipe).
I'd venture a really off the wall guess at about five pounds. As it is, it shakes very little so I don't think I'm gonna try to improve on it.
Thanks for your comment.
