Watching, as always, with interest Brian. One thing strikes me tho - won't the left hand hole (where the marble gets pushed up) need some sort of inverted ramp to prevent jamming?
be interesting to see how that pans out. I just visualise the ball rising and jamming on the 'roof' before it gets to the hole.
I also saved some Archimedes screws from some toner cartridges for use as a ball lifter
