Nice project but using a chop saw to cut the length of the wood as shown in step 4 is very dangerous. A table saw is much safer. If you decide to use the chop saw, then use a hold-down device and get your fingers out of the way.
Nice presentation and in theory sandpaper life is longer. However there is more to sandpaper longevity than knowing how to fold it. The first "step" is to select the right kind and grit of sandpaper for the project. Folding is the second step. The third step is knowing how to use it properly for sanding.Master these steps and you can come out with a beautiful "base" for your finish.Phil RasmussenThe Mountain WoodworkerHendersonville, NC
Great idea and great presentation. It seems that there is some discussion on the pin to hold the arm up. An alternative that eliminates the pin follows:1. remove the pivot pin and route a slot about 1 to 1-1/2" long in the arm where the pivot pin goes.2. glue a board on top of the support brace 3. replace pivot pin with arm. The pin goes through the slot4. raise arm and slid toward the back of the support brace so that the top of the arm goes under the board in step 25. lift and pull arm out to release
