Yes, I was wondering what method should be used to bleed them successfully. The
clamp idea is a good one. My compressor is very basic. I don't have buggy
motors. To build the pressure/vac engine all you would have to do, I assume, is
split the lines going to the engine switch valves so that the engine switches in
sync with the pistons. Right? kind of like this...

Also, I'm wondering if, because of how slow the compressor may work, that two
cylinders should be linked together so that a larger volume of air/vac/oil could
be moved.
I'm trying to think of how to install a resivoir system for the hydraulic
concept. the problem I have is that, the over flow goes into a resivoir tank
right? and then cycles back to the pump. If that happens wouldn't the load
cylinders not recieve the proper propulsion force. If so, wouldn't you have to
make a pressure valve leading to the tank that would only open if the cylinder
absolutely couldn't lift the load?
I'm a little confused right now and I'm going to have to lear a little more
about how a proper hydraulic system works. I'll also try to improve my
compressor design.
Billy.
