Mounting Bracket
The intended wire for clamping in this bracket is the 20 μm diameter tungsten wire borrowed from CMU. The bracket should have the planarity to handle this. Assuming elastic deformation of the bracket around the wires, force of order 100 N is expected, yielding to a force of friction well above the above the elastic limit of the wire (i.e. the wire will break before clamp releases it.)
Choice of Adhesives

Diamond Mounting Trials
Simple wire stretching exercises were performed. The wire is approximated to have to be well past its elastic limit bearing 50 g weight. A thumb screw threading two washers going into a threaded stand-off (long nut) provided a nice 4.8 g weight that can clamp wire. So a wire loop is created by clamping the ends of a wire segment between the washers by tightening the thumb screw.
