Thanks for the reply Michael E, The original unit did use a rack & pinion with a sprag clutch & worked well. It can be seen from the youtube link in my post #3. This unit also required a re set to enable the unit to start from the same position each time as the pickup point on the sprag clutch...

The unit uses pneumatic sensors on each cylinder to operate the valves so the unit is entirely pneumatic. Unfortunately I am unable to use any electrical parts. Regarding using one cylinder: This can be done if you use spring loaded cams. Assuming the cylinder is horizontal with the left...

Hi Benfur you know exactly what the problem is & your suggestion will work. I have managed to get the system working with two valves & four sensors ( two per cylinder ). The sensors reverse the motion of their respective cylinders by reversing the valve controlling that cylinder. The action...

Hi Danger, thanks for the reply. Perhaps I should describe the problem as one disk that can rotate on an axle, the hole in the disk is offset to make a cam. However this offset is not important it can be treated as a concentric wheel on a shaft. In the face of the wheel there are two tapped...
