thanks Larry! that cheese thing works well. i just cut a hole in a plastic cutting board and drilled some holes, then threaded some stainless steel safety wire through and twisted to close. if you have an odd number of holes it all works out. i tried the normal safety wire (i think 40 thousanths?) and it didn't work. had to use the thinest that i had on hand for small fasteners. the holes are about 10mm apart, i think i would go a little larger next time.
