  • Ring gear engine

    Some of you may recall when I started working on this engine. It's based on Elmer's engine but my own design. Sir John helped with the gear profile.
    Well, other paying jobs and my day job got in the way of finishing it, but it finally is.

            John- that vee block was a custom made piece. EDM'd hardened,ground. The block can replace the rear jaw on a Kurt vice, bolted in place. Most times I don't however.

              I wonder if anyone would be interested in details to make this engine?

                Hi Sid,

                Although I probably won't build one I do enjoy watching the build threads. Post away.

                Thanks,

                  I would be interested. I have a '50's style portable drill speed reducer ($1 flea market find) that has an epicyclic gear that could be used. The bearings were shot but the gear system is built like a tank. It is waiting for a project.

                    very unique Sid,

                    I try to predict the way a motor or engine is going to sound by it's design and such, Due to using straight cut gears as part of the propulsion drive I was expecting intermittent whining sounds as the power strokes where engaging and then letting off,
                    What I failed to deduct was the fact that's it's an internal gear which in general has many teeth still in contact at once and is relatively quite when compared to conventional, my prediction was way off as your engine is pretty darned smooth sounding...
