Re: Using a turret? Whatre your ideas on elevator design?

You can do it on the cheap very easily. Like this:

We used a globe motor and a large gear from the kit. For the large gear, we cut out a circle, bolted it to a lazy susan, and then stapled belting around the outside.

...it was absolutely, disastrously the wrong solution for Lunacy, but I think it could work quite well for Rebound Rumble.

Oh, and with lazy susan, belt, and gear in the kit, the net cost was somewhere around $4 for the plywood.

It's worth noting as well that the shooter was very wide because orbit balls were so frustratingly irregular -- methinks you could get away with a pitching machine-style pair of wheels with these balls. (Prototyping is yet to come for us on that score!)
