Jay's gearbox guide

I've struggled a lot with the making of gearboxes. I did find a guide from T3 (http://www.atitd.org/wiki/tale3/Users/EldradUlthran/Gearbox_Guide) and some explanations here: http://www.atitd.org/wiki/tale6/Gearbox_Design_Guide and http://www.atitd.org/wiki/tale6/Gearbox.

Still I kept having problems and mostly tried them on a trial/error basis, which most of the times got me frustated :) so eventually, when I did manage to make them, I tried to write this guide.

Step 1 - What do you need

• Gearbox Assembly Table
• Gearbox design tech
• a stash of Small Gears, Medium Gears, Large Gears
• wikipage for the gear ratio's: http://www.atitd.org/wiki/tale6/Gearbox_Ratios or you can use: http://www.atitd.org/wiki/tale6/Tamutnefret_Gearbox_Ratios
• patience :)

Step 2 - Different gearpairs

• spacer, used to start a new layer (no cost) - to represent it in the photo's I use: 1 ::[IMG][/IMG]
• one step (photo) 3/3 only allows to move in a +-shape (cost=small gears):: [IMG][/IMG]
• diagonal (photo) 4/4 cheap :: [IMG][/IMG]
• 3/5, 5/3 makes a large change in ratio)(cost= medium gears):: [IMG][/IMG]
• two steps up or sideways 5/6, 6/5, 4/7, 7/4 (makes smaller changes in ratio)(cost when using 7gear: large gears) :: [IMG][/IMG]
• knight's move 6/6, 5/7, 7/5 ::[IMG][/IMG]]

• • 4/4 is much cheaper then 6/6 , although with 6/6 you move over large distances
  • 3/3, 4/4, 6/6 makes no change in ratio (photo still to come)
  • 3/5, 5/6, 4/7 makes the ratio go down :: [IMG][/IMG]
  • 5/3, 6/5, 7/4, 7/5 makes the ratio go up :: [IMG][/IMG]

Step 3 - Useful to know

• you always start at 1A, ratio 100ù
• 8 rows, 8 columns
• you always need to end at row 8
• only 30 shafts can be used - = including spacers
• no more then 3 layers/levels are possible
• always put the smallest gear on the bottom, ex: spacer, 3-gear, 5-gear on top of each other, not spacer, 5-gear, 3-gear - it seems it is possible to put a small gear on top of a large gear, but depending on your next move, you can get the message that they are too close to each other: see photo's

• only 3/3, 4/4, 3/5, 5/3, 5/6, 6/5, 6/6, 4/7, 7/4, 5/7, 7/5 pairs can be used

Step 4 - Example of a 1-output gearbox

• used for cartouche and the 1st box used in Stone Quarry
• let's make gearbox: D160-175
  • check the ratiopage: http://www.atitd.org/wiki/tale6/Gearbox_Ratios or you can use: http://www.atitd.org/wiki/tale6/Tamutnefret_Gearbox_Ratios
  • here we see the possible ratios: photo below: black square
  • we need the one with the lowest cost: photo below:red square

• • photo's from the board using the cheap 4/4 gears

[IMG][/IMG] [IMG][/IMG] [IMG][/IMG]

• • photo's from the board using the expensive 6/6 gears - but since we need to make: D160-175 we have to put some 4-gears under the 6-gears

Step 5 - Example of a 2-output gearbox

• used for Springbox, and the 2nd gearbox in Stone Quarry
• let's make gearbox: B100-125 D320-382
  • check the ratiopage: http://www.atitd.org/wiki/tale6/Gearbox_Ratios or you can use: http://www.atitd.org/wiki/tale6/Tamutnefret_Gearbox_Ratios
  • look for ratio's that are used for both
  • here we see the possible ratios: photo (black square)
  • start looking for shared ratio's, preferably at the start!!! then possibly with lowest cost, if there is still choice - photo: red square

• • photo's from the board

Step 6 - Example of a 3-output gearbox

• used for Test of Dancing Waters, the dancing waters mechanism
• let's make gearbox: B240-280 E175-205 H322-375
  • check the ratiopage: http://www.atitd.org/wiki/tale6/Gearbox_Ratios or you can use: http://www.atitd.org/wiki/tale6/Tamutnefret_Gearbox_Ratios
  • look for ratio's that are used for all 3 of them
  • here we see the possible ratios: photo (black square)
  • we need the ones that are shared by all 3 and then if there is still choice, the lowest cost possible

Step 7 - Final

• you'll get a message if your gearbox is not good
  • either your gears don't mesh :: [IMG][/IMG]
  • either you don't have an output in row 8 :: [IMG][/IMG]
  • either you have used up your 30 shafts
• also on top of your board you'll see if your gearbox has the correct ratio
• when your gearbox is ok, then you'll get a popup window: "do you want to make this gearbox .....?"

I hope this guide makes making gearboxes a bit more easier.
