Yes I had the rod end shear off. I am
convinced that the geometry of the system is all wrong. By this I mean
that when you need the cylinder to completely close the door it is at a point
where most of the pull from the cylinder is parallel to the door. Also I
feel that the cylinder should be to free to pivot about its mounting
point. This is due o the fact that the operating end moves in arc to close
the door. If the cylinder cannot pivot the force will impose a bending
moment on the rod end and of course the rest of the system.
Hope that helps.
