Follow-Up To The Last Weird Question
You have two objects that you want to lock together from opposite sides of a rectangle. At the same time, you do not know the exact dimensions of the rectangle -- there could be as much as an inch or two of variation from unit to unit. The obvious choice is two pieces of steel with a screw thread between them that lets you tighten them together. Can you see a way to do this from steel pieces that can be bought off the shelf, or fabricated with a relatively light weight metal brake? The force involved is not enormous.
