[PSUBS-MAILIST] Manipulator arm

Scott,
Gamma uses air cylinders with hydraulic fluid and pump.  The hydraulic system is very standard except it uses air cylinders in place of hydraulic cylinders.

 Is Gamma all air cylinders? Do you just use
 a air compressor? What happens to the air once it is in the
 cylinder and you want to lower the cylinder? Is it
 recompressed or somehow expelled? I really don't know
 crap about pnematics. Haha. Why do all the subs use
 hydrolics and not air. For example
 hydro-lek?Thanks,Scott

 Scott,
 Not sure why you want hydraulic cylinders.  You want
 air cylinders, they are light weight and all aluminum. 
 If you use 2 in bore air cylinders you can run on a 500 psi
 system.  Also air cylinders typically have 5/8 rods and
 that is the most important part.  The rod size is what
 the water pressure is pushing back against you system. 
 Air cylinders have a single o ring on the piston and are
 cheap and easy to replace. If you want ss rods then just
 replace the chrome rods when they wear out.  I made my
 own rods for Gamma, easy peezy.

  Are you using hydraulic cylinders or air cylinders.
