Another project, and I couldn't think of any kind of story to ao along with it (Petrosius can only do so much). The idea came from Hellboy 2, amongst other things, and I'm planning on doing at least 3 different sizes, and some way to connect them. For now, they use a basic paper bearing which I need to tweak a little more. Right now, the gear tends to slip out of it when I turn it.   |

World Works has a crane that turns in one of their sets. It is comprised of two collars of paper that stand vertically with one fitting inside the other. If you did that it would reduce the surface area in friction. You'd have the inside surface of one ring against the outside surface of another, as opposed to the potential of the entire bottom surface of the gear. Additionally, seeing that the two surfaces in friction would be hidden you could wax them without marring the appearance of the gear and the floor.

I was thinking you could use foamcore for the bearing parts, but the cardstock collar idea is even better.

Sorry, i don't get it.... what is it for?

I like it! So the circle allows the cog to stay fixed whilst still allowing motion? Clever stuff.  Three different sizes? Intermeshing? The mathematics will be mind boggling!  |

Sorry, i don't get it.... what is it for? They'll get a kind of grid, and once you have a few connected (if that works) characters can hop around on them and every round one gear is turned, resulting in unexpected changes on the battlefield. Maybe not unexpected, but hopefully interresting  . As for mathmatics, right now every tooth is one inch wide, same for the indents, so I'm goping to avoid mathmatics by casting simplicity on it . I'll look into the collar idea, thanks. |

I know I've fought on turning gears before. And my character was fighting clock-work automatons. I think it was in the Savage Tides adventure path. Good times! When you get it worked up you could share it with the D&D 3.5 die hards. BTW I suspect there might be less slipping with six cogs rather than five, but I may be wrong.

Intriguing idea.
Question:
If they're meant to have a grid on top.... how to keep the grids aligned if the # of cogs is not a multiple of the # of sides of a single grid cell?

I'm thinking of making it a grid-like grid, that is to say roughly divide it in squares, withouteven trying to make it a proper grid. I hope that it'll work as terrain when multiple gear are being used together.
As for turning them, I'm in the process of building the 6-tooth-version, and then I'll test them properly. I'm uncertain whether I should be aiming for a system that works well from a mechanical point of view (and might be a pain to build due to the large number of teeth required and the size of the gears) or go for one that might require a little care when turning but adds the fun that comes from having different gear sizes - as in "you might not like where you'll be standing two spins from now".

Would a combo of your teeth gear with the left one in this picture solve some problem?  It may be made with straws...just thinking aloud |

how about placing the uprights on the bottom? That way the top surface is still clear for minis?
But I think cool looking and moved carefully is the way to go for a scenery piece.

I think the main problem is that I decided to have the teeth as squares to stand on. It would probably easier to construct turning "discs", then one could have the mechanism vanish underneath. I'll check how it turns out once the 6-tooth has been built, but I think there's still some planning left to be done, especially concerning the bearing that I have yet to look at... Either way, thanks for the inspiration . |

two rare earth magnet washers threaded on a dowel... orient them North to North and you'll get a floating bearing!

Have you looked at paper clock designs to get any ideas?
I think there may even be a few free designs floating around the internet.

Yeah, I have some ideas, but I'm struggeling with the software side, and with time constraints. One of the problems being that I could do one part that my software at home cannot do at work, but there's some compatibility issues and besides it wouldn't be a karma-earning thing to do . |
