Attached below is a picture of a box puzzle that can be found in the Wood Magazine, Issue 258 Dec/Jan 2018/2019, page 52. The puzzle is made from 31 pieces of Walnut. I used the jig shown below to make the dado cuts in the Walnut pieces. I do not think that I could have solved the puzzle without the instructions found in the magazine. It took over 45 minutes to solve using the magazine with two people and several rubber bands to help hold the pieces together while placing the next piece. I almost hate to take it apart so I can apply finish. This puzzle was fun to make and is a conversation piece.
