What I learned is that the thickness of the wood doesn’t matter, and the length isn’t too critical. Widths from 2.5” to 3.5”, and most with a thickness of about 3/4”. I made a variety of them in lengths ranging from 9-12”. Again, you can get the kids involved here and have them choose a color and even apply it themselves (with supervision). Find that really cool piece of scrap wood you’ve been saving and make a gift for someone. You’ve seen these before, but use this opportunity to make them your own. It also makes it easy to move around once you’re done playing. This will fit your pieces like a glove and make setup a breeze. Then cut a piece 11.25” wide and 27” tall. Cut a piece of 3/4” plywood 10.5” wide and 27” tall. If you want to make your life easy, I recommend making a two sided case for transport/setup. Dump some alcohol in, squirt some dye in, then wipe your piece with rag dipped in your mixture. All you need is some transtint, some denatured alcohol and a old glass jar. This would be a fun project to give to the kids, just let them go nuts with the random colors. You can get just about any color you want and custom blend any color you can’t get. Once dry, I gave a quick coat of shellac to provide a little more protection. Then painted an equal number white (18 of each). Just sanded them semi-smooth with 100 grit on my orbitalĪfter sanding, I decided to make this a sports themed project and dye the blocks orange and black. After getting all the ends rounded over, I went to work sanding them. You could also just round them over with your belt or oscillating sander. I wanted the sharp end cuts to match the rest of the piece, so I spent a little time and rounded the corners over on my router table with a 1/2 roundover bit. If you want to make it a little nicer, and/or keep the kids occupied a little longer, go ahead and read on. You will be able to play a totally decent game of giant Jenga with your 54 pieces of 2x4. You can open this, click it and then use the controls to rotate it and look around the model.Ĥ) A zipped copy of all of the Alibre files for opening, viewing and modifying.Depending on how committed you want to be to this project, you can actually be done after cutting your 54 pieces. Some laser cutters prefer this.ģ) A PDF of the Alibre model. I've included:ġ) The DXF files for laser cutting or for printing 1:1 scale to glue to woodĢ) An EPS file, converted from the DXF files. The files for either method are attached in this step. The joints holding the pistol together are all interference fit, designed to either fit together tightly with no modification or after a very light sanding.Ī laser cutter would be the tool of choice for this project, but it could easily be made with a paper template glued to 1/4" ply and then cut out with a scroll saw or a coping saw. The trigger was designed so that it was its own spring, I didn't want to have to use a spring or a rubber band like in the acrylic jenga pistol that I made last year. While designing it I wanted to keep it as simple to build as possible, with minimal screws and bolts holding it together. I went through several iterations to get to this stage with various attempts at getting the plunger, trigger and plunger guides correct. The jenga pistol was designed in a trial version of Alibre Design, my favoured CAD package.
