Things You'll Need
Instructions
Study and conquer a variety of tavern puzzles and choose one that seems simple to reproduce, such as Old Shackles. Put your own twist on the puzzle to customize it.
Measure circular or bent puzzle pieces for similar replication, using a fabric tape measure.
Cut to length a straight section of coat hanger with the wire snips and bend into shape using pliers, according to your idea. Light gauge coat hangers may be workable by hand but may not be strong enough to hold up to the force used by a player when working the finished puzzle.
Put on safety goggles. Place the wire length on an iron or solid metal surface and slightly flatten the ends needing drilled holes for attaching jump rings or other parts, with a hammer. If placed on a soft surface, such as a wood-top work bench, the force of the hammering will only push the wire into the wood without flattening it.
Make the removable object piece last and to spec--just barely big enough to fit over all of your other constructed parts when manipulated in play.
File and smooth all rough edges with a file, grinder and sandpaper.
Test for accuracy by playing. Tweak as needed.
