Converting a ratio to a set of gears used to be a laborious process
Prone to mistakes and fraught with inconsistencies
This Is No Longer True

Charles Mold changed all this with his book containing pre-calculated ratio's
Published in the early 1940's, Mold's Ratio's took several years to complete

It had tables for 5539 pre-calculated ratio's
With a range from 0.40000 to 2.50000
And accurate to 5 decimal places
These Restrictions Are No Longer Acceptable

In 1960, along came the Pfauter Change Gear Tables
This book had tables for 26,000 pre-calculated ratio's
With a range from 0.100000 to 1.000000
And accurate to 6 decimal places
These Restrictions Are No Longer Acceptable
Today we have the opportunity of utilising a computers speed and accuracy
A well written program can eliminate any chance of error
And achieve repeatable results
GeaRatio calculates unlimited ratio's.
GeaRatio has an unlimited range.
GeaRatio displays accuracy to EIGHT decimal places.
