Making box joints at the table saw calls for the use of a specialised box joint jig that often has a tall auxiliary fence to support the workpiece. The problem with having a tall fence is that it requires you to bend over the table saw after every pass, straining your neck and back to see the workpiece and index it over the key. This can really take its toll on your comfort when you’re making multiple box joints.
To avoid this situation, I decided to let technology help me out by using my smartphone’s camera to aid in positioning my workpiece. But I couldn’t just set my phone on the table saw without some kind of support. So I made the cradle shown here to hold the phone.
Simple build. The cradle consists of a piece of plywood sandwiched between two pieces of Masonite and glued together. A couple of rare-earth magnets epoxied into holes in the bottom hold it in place. My phone is also in a protective case, so I sized the cradle accordingly.
