you could make the planetary gear something like this The slanted teeth drop the ball onto the outside track and the catch drops it at the right moment so it's aligned with the maze. |

Good suggestion. That'd work awesome. The only problem being...I can't get that laser cut. My project must be laser cut in order to get it done in time. |
| ItchyD:
you could cut 2 plates, the back one with the teeth, and the front one with the track and catch, then lay them atop each other to make the planetary gear. You wouldn't need to slant the teeth if they were thinner than half the width of the ball, it would fall down onto the track. You would need to chop a tooth out of the maze for the catch / ball to pass. I'm making a big assumption here that you have choice of plate thickness haha I do love this thing though!! Also maybe I'm not thinking clearly but what do you need the second small gear for? Wouldn't it be ok to have the maze and planetary gear going different directions? Plus you could make the maze way bigger... |

I still don't get how that little track is going to catch the ball and drop it into the maze. In fact, now that I look at it, wouldn't that track segment interfere with the outer gear from turning a full 360 degrees? |
| JonnyBoy:
There are missing parts from the rendering you saw. The little track on the planetary gear is going to be crammed full of ball bearings on both the top and under the bracket, meaning the inside segment of that planetary gear will be "floating". I've prototyped it and it seems to work well. It should be lasercut by the end of the day, so I'll get some photos. No worries. The second small gear is in place in order to keep the direction of the maze the same as the direction you crank. Also, it kind of makes it look more like a watch, which is kind of fun. Here's a picture of me playing with some foamcore gears and looking goofy. |
