mtairymd Posted March 19, 2018 Report Share Posted March 19, 2018 This simple wooden lock puzzle will challenge your mind. You are given three wooden blocks. The goal is to assemble them in the cross pattern shown. The last CAD picture shows the solution sequence. Solution Video: https://youtu.be/1hxpYzytDTE Solved Pieces Used a scrap 1x4 piece of cedar Rounded edges Cut down to 6" lengths (made extra pieces). As pointed out in the comments, this is the wrong way to cut a board due to the kickback hazard. Router for slot Repeated 3 times. I used band saw (not shown) for the notches. Overall Size Iso View Part 1 Part 2 Part 3 Solution Start with Block 1 (green piece) Slide Block 2 (purple piece) through slot Slide Block 3 (cyan piece) down and through notch Slide Block 2 towards the center to complete the puzzle More Info here: https://www.instructables.com/id/Wooden-Lock-Puzzle/ Thanks for viewing!

Yeah, I know kickback is an issue but that was me being lazy and forgetful. I also know that being lazy will get you hurt. Thanks! Quote Link to comment Share on other sites More sharing options...
