gearscube Anonymous
I got my Japanese friend to email the maker of the gearscube (see picture). The maker is thinking of becoming a professional papercrafter, so he doesn't want to give out the template. He's pleased that someone from abroad saw it and liked it.

I may have a go at myself, although I'm only a beginner.

This wouldnt be all that hard to design if you had the Machinery's Handbook and know how to work equations. I'm working on some gears for a project now, so I'll have to begin making this too.

One question though: how far do each of those gear edges extend into the middle?

well if your going to attempt it you must have the model.... give it to us

I've not heard of the Machinery's handbook - certainly interesting. I can - or used to be able to - work equations.

I think - judging by some of the other pictures of papercraft that this guy has done - that the cogs extend nearly into the centre, keeping the axles small and the drive surface from the base-cog to a maximum. It seems to me that it would be more robust and run smoother like this, although this is only guesswork.

This is a n00b question: how the heck would you do the cogs using cardboard?

It's awesome how the paper gears grab into each other when turning, but the turning itself is probably done by cheating a bit, using small metal rods and gears.

I was thinking about that. I think there's a central cog at the base which drives the whole thing. The others might be on free-wheeling axles, mounted as pairs.

Yeah that's probably it. But sometimes when you find out it's not all paper, the thing loses all its awesomness, but on this one it's still awesome to see how the paper gears grab into each other.

It's probably also why it's not up for (paid) download/purchase yet: he would have to send along the gears as well, or at least tell people how/where/which exactly to buy and how to create the mechanism. and I don't know how many you'd need exactly, but they can be quite price (3-5 bucks for a small gear, so what if you need 10..?)

I think there's a way you could do it without gears; it would require thought and experimentation.

I can see your logic, though.

There's no way these cogs move, all because of the ones on the edge of the cube. If they turned, the edge would move.

I agree, there is not enough aspect distortion along the planar truncation of the conical gears to suggest this gear cluster is capable of rotational motion.

Put the machinery guides down, anon! You'll put somebody's eye out with that much language! XD

yes there is a way the cogs move, there is a rod that turns the one on very top and the sides are the same (or at least mostly the same, as you can see they are slightly different untill the pieces rotate (watch the video on his site and you will understand what im talking about)) you will also notice that they are not rigid and slightly bulge out and that they dont go all the way to the center, if you look closely at the ops picture, the bottom most gear you can see where the gears end if you look in the gap between the gear teeth, all in all this is actually very possibly and shouldnt be that hard to make if you are willing to go through a few testbuilds to make sure all the cogs are turning correctly

oh ho! /po/ i have made an exciting discovery, the picture on his website and the video of the gears moving are in different positions, in fact its the opposite sides of cube, therefore we know what all of the sides look like but the bottom, but the bottom side of the lower gears can be seen in the animation so therefore it would not be hard to reverse engineer this puppy MUAHAHAHA i shall try my hand at this tomarrow if i have time, right now im really tired and would rather like to sleep

oh fuck this after seeing that video we now NEED to have that papercraft

Seconded. It looks so cool when it's turning around.

If anyone wants to do it themselves, here's how I recommend you go about doing it. ( not me, I just tried it to see if I could) You'd want to make two cylinders, one with 30 sides and one with 20 sides. Select every other face and extrude them out and shrink them narrower to make a cog shape like this center cog. Take the bottom of the new "cog" and reduce the points down into a single point. You should now have two pointed cogs, one with 15 spokes and one with ten. Point the tips of each cog toward one center point. Duplicate, rotate, and scale the cogs like the pic/video. Boolean each cog with a cube and there you go.

The trick is not making the gears, with some patience everybody (well, most /po/eple lol) can figure out how to make them.

The trick is the mechanism that makes them rotate: THAT's the cool part...

the mechanism is fairly simple, its a vertical cog that extrudes out a lil bit (almost to a point) which when turns turns a horizontal cog and makes the entire thing spin, there ya go problem solved

>>75283
lol yeah "problem solved..."
Try it out some time, provide some schematics or even a prototype when you get it to work, and you'll see there are some more problems to be solved... ;o)

hey i am making it, slowly but surely, im going off to college in a week so i dunno when it will be complete, hopefully before the end of september
