Second, and more import, the slave to master throw ratio is a function of the area of the cylinders, not the diameters since the volume of fluid pumped equals the area times the throw and area is proportional to the diameter squared (area of a circle = pi x diameter squared/4). So a one inch throw on a 3/4" master driving a 1" slave will result in a 9/16 "(3/4 squared) throw at the slave, and a 1.25 " throw on a 3/4" master will produce a 0.703" throw on a 1" slave.
Correct. Sorry if I'm confusing. My opening statement is only a "check my understanding" feedback. (Habit from thousands of flight crew debriefs.)
Volume is volume, thats Why I recommended a a 1.125" dia coupled with his current 1.0" slave for overdrive. Or possibly reducing the slave to 3/4" giving him a 1:1 movement on input and output.
