I've used super glue before and it works, but I've tried accure glass and like the results a bit better. I used to wet leather squares, stack about 7 at a time and squess in a shop press and jig, let dry then soak with super glue and re-stack and compress. Now I just brush the squares with accure glass and soak them good and compress. I use a 20 ton shop press and a jig made out of 3/4" flat bar, don't forget the wax paper to keep from sticking the press and dies together. Block comes out looking like a block of stabilized wood and I just trim the edges with the bandsaw, drill and use like a block of wood.
