Re: Pneumatic speed
Increasing the cylinder diameter increases the force, but decreases the speed.
Adding more cylinders can maintain the same speed, and increase the force.
Some speed increase can be obtained by opening up the exhaust port of the cylinder to the atmosphere (remove all fittings and use the bare cylinder port) and retracting it with a spring or elastic, like surgical tubing.
The problem with having a cylinder directly in the loop is that it will act as a shock absorber by slowing your kick to the speed that air can be pushed out of the open end of the cylinder or pumped into the charged end.
One way around this problem is to latch the cylinder partially extended and precharge it to get around the 1/4" feed tube restriction. Then release the latch.
