im making a back plate kind of like a exo skeleton design like normal plate but more contoured to a human back. im using 3/16 6061. tank mount same material but im trying to design a cam lever to lock down the tank. only 1 lever with no cordura strapping. a hook and lock idea. i will load up the pictures when its done. so its more of a pictue tutorial. if anyone has ideas re the tand cam lock id appreciate it.
