This project has some options for the wheel section for you to decide on. You can opt to skip wheels altogether in which case you will make all 4 legs the same length and skip the last 2 steps in this post. You can also opt to either purchase wheels, or create your own wheels (I would recommend giving this a try) in which choice you will simply carve circular shapes from 3/4” stock and drill a hole halfway into the wheels in the center to hold the axel rod (dowel). Easy peasy… Consider using a specie of wood suitable for outdoor use such as cedar, redwood, teak, etc., and be sure you choose galvanized or coated hardware to avoid rust. Be sure you finishing materials and products are suitable for outdoor use as well. Read through the entire set of instructions and all comments before beginning this project. If you print out or save plans, be sure to check in on my site to be sure you have the most up to date set of plans, as I occasionally update things for ease of building or buying. If you are new to building, read through the GETTING STARTED section and other articles found under the BUILD tab in the menu on my site, it has valuable information about how to get started, tools and techniques. If you are unfamiliar with the finishing process, visit my Finishing school for some tips and tricks for painting like a pro and for special finishing practices. Use glue to secure your joints and Consider Painting or Staining individual sections prior to assembling. This makes the paint application virtually flawless. Coat with a spray on Poly or Wipe on Poly to protect your finish and your piece and it will last for ages. Adhere to all safety standards and guidelines, and be sure you follow safety protocol throughout your build. If you are unsure about whether you are building safely, run a quick online search for the tool or technique you are using, or contact me via email or post to the forum before you move ahead.
