[TheForge] Air Cylinder (actuators)

Mon Jan 6 12:55:04 2003

If you are going to try to make it a "Self contained" hammer, I think you
will find that you will need a 4" to 6" cylinder for the hammer and another
of equal size for the actuator. The reason being that in a self contained
you are working at low pressures so you need more cubic inches. A 2.5"
cylinder would need about 5 times the pressure of a 6" cylinder to move the
hammer.
I started to build an 80# self contained using a 2.5" hammer cylinder and a
6" actuator. I ended up converting it to a Kinyon style using the 2.5"
cylinder.
