Locking pivoting metal plates. How?
I'm having some problems making two metal plates lock together. The two metal plates are supposed to pivot against each other as they form the pivot point for a large compass I've made for drawing large arcs in metal and fabric. The pivoting section is made from a couple of corner supports made from some kind of metal.
Please see the photos.
The problem I'm having is I can't seem to get the two plates to lock together and I'm wondering if there is a standard way of dealing with this kind of thing. They can't move once locked together (as they form a pivot point), but when loosening off a lever locking bolt which passes through the two holes, they should swivel on that bolt. The pictures are self explanatory.
How do I get these plates to lock together without moving? I want to be able to hand tighten them with the lever locking bolt I have which give me plenty of leverage when tightening. Rubber washers and all the washers I have used so far seem to slip. Fiber washers seem to be the best but they still slip.
Any tips, clues on how to deal with this? Thanks very much. (see photos below).
