Knex Ball Machine Element - The Elliptica

This is a small element that I made that is meant to be added onto an existing ball machine. It works very well, so I thought I'd post it for all you folks.

Full credit for the concept goes to KageKumo, from his ball machine, "Knex in the apartment".

hate to break it to you but netchman already made one of these for his ball machine a year ago :(

@TheClavus2 I'm not really suprised :-/

I gave credit to KageKumo, I got the idea from him.

[NtwProductionsDrums]

Very creative!

[CanadianKnex]

@NtwProductionsDrums Thanks!

Please could you do some really basic tutorials like for scaffolding and chain lifts? I have ideas and want to build a little track with a few elements but I don't know how to start. I even bought all the pieces!

[smrp1984]

Awesome and original. Very nice!

[CanadianKnex]

@austron That's an honer to hear that from you :-D

(your new machine looks beyond cool, by the way....)

@CanadianKnex New ball machine? I look forward to it ^^

[CanadianKnex]

@austron Both excellent ideas :-D I'll try the one with elastics, I've just installed this onto my new ball machine though, so the other one will have to wait.

@CanadianKnex Interesting. If you haven't already, maybe you could build a simple ball machine with a motorized lift feeding directly into this element and let it run for several hours to see if the error correction works for a long period of time :) Another idea I thought of after posting this was to wrap thick-ish rubber bands (maybe the kind that hold broccoli together?) around the wheels, that might improve their grip on the tubing.
