[QUOTE="Tathradj, post: 226205, member: 2436"] To work out your ratio's, Divide the highest number by the lowest number. 36 teeth Large 12 small 36 divided by 12 = 3 every 3 revolutions by the small gear or cog will equal 1 turn by the large. you have also nearly multiplied your torque by a factor of 3. There is some loss with friction etc. This is a bit rough but will put you in ball park. Or, Use this, [url]http://www.calculatorsoup.com/calculators/math/ratios.php[/url] [/QUOTE]
