I caught that while you were replying, Tav.

Yes, but you have to have a frame of reference, which is "per each turn of the handle"; i.e. revolutions (input)

Your first equation says "circumference = IPT / gear ratio".

At the end you say "gear ratio / diameter = gear ratio". While this already must not be true, take it further and substitute into the first equation.

circumference = IPT / (gear ratio / diameter)

or

circumference x gear ratio / diameter = IPT

which simplifies to

gear ratio x pi = IPT

I'm pretty sure that's not right.

good lord...let's get some sleep.
