Gearbox Ratios
From A Wiki in the Desert
Links
Ratio = The numbers required by the gearbox.
"(3/5)" = 3 point 5 point and / means side by side
the * sign = start stacking gear at last gear previous.
First find your ratio: in this case: A311-A423-the 311 and 423 are what you look for along the left side of this chart. The rel Cost is the column that'll determine how many gears (approx) you will need to 'make' the gearbox. Must start in column A1, and End (in this case column A) on the number 8 at top. Where you end on the 8, per alphabet is what the final gearbox output will be.
