Just watched this video 4 times a row with Greg, who is madly in love with the geneva drive. Although he notes, pausing to have some milk in his sippy cup: "Fishy has a very complicated way to get a drink! My way is very much easier."
We found a picture of the whole machine on twitter, but very dark. Greg wants to know how the geneva bit is connected to the main assembly line belt. Also he is impressed that you made it all yourself and says "good job!" for welding at your house.
There is a chain that goes down from behind the geneva wheel to drive the big sprockets on the right side of the conveyor. You can just see it behind the conveyor starting at 0:10 in the video.
I could send you a copy of the 3D model (originally in Blender, but I can export to any standard format) if he'd like to poke at it.
Fun engineering tidbit for him: All of the rest of the connections are rollerchain, but the motor drives the geneva cam via belt and pulleys instead. That way if something gets jammed, it can slip instead of tearing itself apart!
I'd love to see a picture of his creation, when it's done.
