I've seen many "cases" that are simply two pieces of
plywood held together with all-thread and some others made of
aluminum with all-thread. Everything I've read says prismatic cell should be compressed. But I have yet to find any solid information about just exactly, how much
compression is needed. How much
compression is too much? How much is too little? The cells I have have a very slight bulge in the middle. Should there be enough compression to 'flatten' the cells out, so that the cells are touching each other around their perimeters? Or would that be too much? And what would be an indication that there is too much compression?
