Idiosyncratic gear ratios
Peter Nolan posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
A little while ago I became interested in some slightly unusual gear ratios (for a few reasons covered below). More recently though, I gained access to a laser cutter, and hence the ability to make custom lego gears. With this in mind, I decided to work out all the possible custom gear combinations that will fit on a standard technic beam (ie all the combinations where the centre-to-centre axle distance is a whole number of studs). I found the website https://www.cailliau.org/en/Alphabetical/L/Lego/Gears/Dimensions/ handy for figuring out the meshing. I'm not sure if this is of interest to anyone else, but here is what I found: One custom gear with one standard gear (Standard gear, Custom gear, Ratio) 12 52 3/13 16 32 1/2 16 48 1/3 20 44 5/11 20 60 1/3 28 52 7/13 36 44 9/11 36 60 3/5 Two custom gears where both have a prime number of teeth (Custom gear, Custom gear, Ratio) 11 53 11/53 11 37 11/37 17 47 17/47 17 31 17/31 23 41 23/41 37 59 37/59 19 29 19/29 13 19 13/19 43 53 43/53 37 43 37/43 53 59 53/59 There are also plenty of 'loose running' combinations where the centre-to-centre distance between axles is only 0.5 mm off an integral number of studs. I tried one of these, and it seemed to work fine. Loose-running combos (standard gears in bold) (Gear 1, Gear 2, Ratio) 8 23 8/23 8 39 8/39 8 55 8/55 11 20 11/20 11 36 11/36 12 19 12/19 12 35 12/35 12 51 4/17 15 16 15/16 16 31 16/31 16 47 16/47 19 28 19/28 20 27 20/27 20 43 20/43 20 59 20/59 23 24 23/24 23 40 23/40 23 56 23/56 24 39 8/13 24 55 24/55 27 36 3/4 28 35 4/5 28 51 28/51 36 43 36/43 36 59 36/59 39 40 39/40 39 56 39/56 40 55 8/11 55 56 55/56 SO the big question is, why would I be interested in such things? The first is that a while back I built a 'phase revival' machine (video below). In this situation I wanted a ratio close to, but not exactly 1:1. In the video I used 20:24, which means that the first cog has to rotate 7776 times before all the parts line up again. If I used a custom ratio of 39:40, and had 11 modules instead of 5, it would take 10 billion years (rotating the left-most gear at 1 revolution/second) before all the pieces realigned! I'm not quite sure why, but the idea of a machine that takes the entire lifetime of our sun to reset is appealing! And now for the prime numbers... I've been interested in making lego spirographs recently, and the key to interesting patterns is the lowest common multiple of the two gears. If you have a gear with a prime number of teeth, you are pretty much guaranteed of getting lots of 'knots' in the design. In the second video below, I used a 43 tooth gear meshed with a 36 tooth gear. To actually make the gear profile, I used https://www.festi.info/boxes.py/Gears?language=en with a modulus setting of Pi (3.14) to make lego compatible gears. You also need to tweak the burn correction depending on the cutter and material. I also set 'profile_shift' to zero. I suspect that a little more fine-tuning would be required to get the best result, but this is a good starting point. I hope that someone else finds this interesting! Ahhhrrgh. I can't delete the table below! Please ignore.... -
Hello custom-izers! I've been wanting to make some custom clones (or at least design some decals). Before I start, I'd like to know if anyone has, or knows, a good decal for this kind of clone: http://alpha.brickli...ode 2]#T=S&O={} That torso is used (I think) on all the new phase II clones as well. When I search the EU index, and the web I can only find decals for this kind: http://alpha.brickli... Wars]#T=S&O={} Also, which is you're favorite? Thanks!

[AoM] Tower Phase 1: Using the creations of mother nature
Dutchy posted a topic in Guilds of Historica
This is my first entry for the Age of Mitgardia freebuild challenge After William, Maxime and Alexander walked trough the woods of Mitgardia for a few days, they decided that it was time to search for a place where they could rest. They were exhausted and needed sleep and food. They found a river full of fish and now they just had to find a safe place to rest. There was a big rock a few meters from the river and after finding out that there was a hollow space underneath it, they decided that this would be their home for the next couple of days. William climbed on top of the rock and had an amazing view. He could see that they were not far away from a little village, because he saw smoke coming up above the hills, but for now, they're too tired to travel further. William stayed on top of the naturally shaped tower to watch out for any hunters or dangerous animals. William Bright on top of the rock The hollow space underneath the rock, covered with leaves to protect them from unwanted visitors. Without the minifig. I'm a newbie to building MOC's and the small amount of bricks I have doesn't really compensate that but I hope that, with your C&C and these phase builds, I keep getting better at it. So, I would really appreciate any C&C from you guys Thanks for viewing.
