So.........(said with a
) what do we think the spring is that reacts like this. If the idea is that plastic has a higher elasticity and enough strength to do the job then Delrin/LD PE/HD PE would be up to the job and easy to make in a backyard. Hence I'll use the alloy plates until I get the design sorted and then make for out of plastic and see what results.
Some of these projects just evolve to much while they are in the process
