Hi Henry

If you want to use CA hinges, get the ones from Sig. their as strong as you'll find. One hint though. when you install them, slot both sides with an exacto knife, slip the hinges into the one side and then into the other. Don't glue them seperately. Once it's all together, 2-3 drops per hing per side, and let it set for a while. When it's cured, flex the joint to loosen up the hinge line. Your surfaces will never come off.

BTW, whose A-4?
