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!
That's awesome! I wonder, though, if some sort of gearing system (perhaps a red gear rolling along a rigid k'nex chain) might work better? It seems as though if this were installed in a ball machine, the vibration of the machine could, over time, knock the wheel out of alignment. Anyway, very inventive, I may have to experiment with this design myself.
@austron Thanks! I did indeed attempt that very suggestion - using red gears on a fixed chain... None of my prototypes worked, so I just went with rollercoaster tubing. I find that the wheel jumps back a little bit upon contacting the bumper at either end - the wheel actually skids on the tubing just slightly, and I find that this corrects the wheel if it is too far over to one side. I'm sure that if this was built on a larger scale, the margin for error would be much smaller, too.
@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.
@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.
hate to break it to you but netchman already made one of these for his ball machine a year ago :(

@austron That's an honer to hear that from you :-D
(your new machine looks beyond cool, by the way....)
