Jay's how to make gearboxes

1: use the following ratio's: http://www.atitd.org/wiki/tale6/Gearbox_Ratios or http://www.atitd.org/wiki/tale6/Tamutnefret_Gearbox_Ratios

2: a 3-gear must be next to each other, up or down = used for small distances

3: a 4/4-gear, a 5/3-gear or a 3/5-gear goes diagonal

4: a 6/5-gear or a 5/6-gear or a 7/4-gear or a 4/7-gear 2 step apart up or sideway

5: a 6/6- gear or a 7/5-gear or a 5/7-gear uses a knight's move= 2 sideway and 1 up

6: use of a 7-gear is pricy = large gear

7: use of a 5-gear or a 6-gear = medium gear

8: use of a 3-gear is small gear

9: use of 4/4-gear is cheaper then a 6/6-gear = 2 small gears instead of 2 medium gears

Meshing

If two shafts are near each other, a gear on one shaft may mesh with a gear on the nearby shaft. This depends upon the sizes of the gears involved, and how far apart the shafts are. Adjacent: gear sizes must sum to 6 (the only possible combination is 3 meshing with 3) Diagonal: gear sizes must sum to 8 (4 meshes with 4, or 5 with 3) 2 steps apart: gear sizes must sum to 11 (6 meshes with 5, or 7 with 4) "Knight's move", 2 steps away then 1 sideways: sizes must sum to 12 (6 with 6, or 7 with 5)

To mesh, gears must also be on the same layer, i.e. both being the first gears on their respective shafts, both second, or both third. If the sum of sizes of gears between a pair of shafts is greater than needed to mesh, they are too close and you must remove one. This includes spacers, which count as greater than 1 (but less than 2) for meshing purposes. For example you can not put a spacer adjacent to a 5 or 6 gear, and you can not put a spacer either adjacent or diagonal to a 7 gear.

To minimize conflicts with adjacent shafts, generally put your small gears on the bottom layer with your medium and large gears on the second or third layer.
