With apologies for the lack of posts over the past few days. That said, I've not been idle. I've been experimenting with Geneva Stops. I've tried a couple of different ways of mounting the drive pin and worked out how the geometry works with different numbers of slots in the main wheel.
I put together a prototype that uses six slots.
…only to find that is didn't fit in the box.
To finish up I'm creating a couple of new projects, one using a six slot Geneva stop and one, below, with a four slot Geneva slot and a working title of Bunnyvision.
