Oops! Sorry about that.

Second, in response to Jurgen's post, I think feedback would only solve half
of the problem.  A better design, such as a back pressure limit switch would
do much more for real pneumatic control.  A lot of the pressure depends on
the load of technic parts that the cylinder has to bear, therefore it is a
lot easier for a cylinder bearing a large weight to retract than it is to
extend.

Just to clarify my original post. I am interested in more exact control of
both position and applied force.

I am interested in trying to build mechanisms found in read life things like
cars and was thinking about power steering servos when I started playing
about with pneumatics. Perhaps this is a bit hard for Lego:-)
