The mica pieces are in there to make sure the two plates of the trimmer remain insulated from each other. One can cut pieces from the thick, clear plastic used for clear packaging over many products these days. Just cut a piece that is the same size, or a tiny bit bigger than the mica, and drill an appropriate hole, and use that as an insulator between the two plates. It works OK.
