[MrForbes]

here's an example of knocking the ball off and catching it...

and I think there is video of it somewhere also, but I can't find that just now.

(they've reinforced the "twisty" parts since this picture was taken!)

Are you talking about hitting it off with some device, or actuating something and then running into the ball? Has anyone calculated approximate forces required to do either of these actions?

[MrForbes]

You could just run into the ball, I think 842 either runs into it or flips up the arm to hit it (ask them, they'll probably tell you). Try it, see what happens.

As of last night our plan was to have a 2" diameter pipe with a 1.5" pipe inside. Mount a pulley of some sort at the top to prevent cable wear and friction, and then increase the inches/sec by either attaching the winch spool to either a gear geared up to a better ratio or by using multiple pulleys.
