Here we go. I finally got some pictures of my progress.

The tank represents the load on the circuit.

And this is with the ram for the load. I am very pleased to find that it
works.

Its interesting to me too. Rather odd that the two separate problems, not only
came up at about the same time, (I asked about the hydraulics.) but that they
are directly related.
