The problem I am having has to do with the rod attachment to the air cylinder. I can bend the metal rod to enter the hollowed out wooden piece attached to the lid, but how do I keep the rod firmly connected to the cylinder?

Since I am completely new to this - if you have improvements on the design, or better purchase suggestion please let me know.
