It took me a little while to figure out what was going on in there. When the band locks the drum, the "dog bone" can't rotate, it reacts by pushing the output shaft the other way, it slides up and down on the cross shaft to follow the drive and driven shafts as it's doing this. In neutral the drum would rotate, in forward the clutches lock everything together. It would present a balance problem on a high speed motor, the only time it would be balanced is when the dog bone is in the center. |

Once again with clarity and few words "Professor Castagnos" Has enlightened the class ! Or maybe just me? that sliding dog bone reversing the output shaft has interrupted some of my sleep latley ! Sometimes I need to see it work to understand it.
Thanks J.B.- heading for N. fla after sending these posts, will arrive in Donaldsonville Friday midday, looking foreward to
J.B's annual Belle River Get together this weekend. The boats and engines, the special people and all things good, Cajun Country is the place to be !

Does any one have a transmission like this? I am in the same quandary as Richard is; I can't quite imagine it working. It would be nice if there is a video of it. Frank |

Frank, I thought about it all day, came home and built one. It's not fancy but it works, when Miro comes down maybe he can use his Youtube skills to post it. It's not ready for a boat, made of coat hangers and plywood. |

I assume it uses some type of this technology.

It looks like in reverse it would act like those old right angle gearboxes that have no gears. Tuckahoe has one that has the top removed so you can see it working. |

I think the name for the Tuckahoe right angle drive is "Scotch Yoke" Bill Wilock had one and he was of that generation who would know and that is what he called it. |

JB has once again proven his incredible ability to explain a complex problem so us mere mortals can follow with some understanding of what is taking place. Thank you Miro for bringing us this really ingenious solution to a not obvious mechanical problem!!! |
