RE: Looking for a P38
Just a thought here; Pete, I know you are past this step, but instead of using wheel collars on the cylinder shafts to limit travel, I'd work lengths of brass tubing that fit over the shaft to the correct length such that they are squeezed between the bottom side of the clevis and the end of the cylinder because to limit stroke. I know that as soon as I had to change the actuation length on the cylinder I'd end up with a dent on the shaft from the wheel collar setscrew right in line with the O-ring and the system would leak until empty... And even if the dent didn't end up on the o-ring, it would have a slight burr on the edge of it so it cut the o-ring on a stroke and make the cylinder useless. So now that it has been thought of, it will happen...
