McMaster Carr or WW Grainger, do not remember for sure but someone sells valve adjustable gas struts. Open the valve and release pressure until it is where you need it. I have no idea what happens if you release too much pressure? Maybe more can be added, maybe it can't, I have no idea. I know someone who has one on his canopy but I have not questioned him about it. I have been told that the big part (gas and oil end) goes upward when extended, the small shaft should be coming out the bottom when extended (inverted that is) the reason is said to be that the seals where the shaft comes out will dry out if in the opposite direction. If you look at the gas struts on auto hoods, van hatchback doors etc, the shaft comes out the bottom on all of them when extended. Larry H.

The oil is for damping, so you can get a smooth, controlled steady movement. Proper operation depends on which end is up. Welding will most likely destroy the elastic seals. A better approach is to get the gas springs sized for your application. The gas springs are rated in pounds force at full rod retraction. How much PSI that turns out to be is not of any concern. As the rod extends, the force will steadily diminish until it hits the stop; the
