BUILD Instructables Acoustic Electric Wooden StompBox with Piezo PickUp

I constructed this piece as a contest entry at instructables.com The direct link to the project is http://www.instructables.com/id/Acoustic-Electric-Wooden-StompBox-with-Piezo-PickU/ This type of stomp box is a percussion instrument normally played by tapping a foot on the top surface but may be played by hand while held under the arm or on the lap. It is sometimes played with a hard tipped drum stick or a rubber tipped mallet. This is not a solid state or tube type electric guitar effects pedal. The only electric or electronic components in this build are passive. Demonstration of the completed unit being tested is at /watch/43L_oaiHv56H_ For this build, I used the following: MATERIALS -------------------------------- .180" Luon ply wood .0625" synthetic felt various scraps of wood CHEMICALS and SUBSTANCES -------------------------------------------- PVA glue clear liquid glue hot glue silicone solder solder flux shellac cyano acrylate denatured alcohol PARTS and COMPONENTS ------------------------------------- piezo element 1/4" female mono audio jack thick hardware store washer 22 AWG copper wire polyfill fiber padding cardboard tubes TOOLS -------------------------------------------- table saw power sander soldering iron hot glue gun 3" paint brush razor knife hemostats various sized "C" clamps 12" quick slide bar clamps laptop computer 50 watt CO2 LASER LASER control software graphics software for raster and vector compressor with pressure regulator and air drier dremel rotary tool bits for dremel dremel workstation bungee cords and wooden bar for makeshift clamp/hold-down dust mask safety glasses cotton work gloves strap clamps/tie down straps sandpaper - 80, 100, 150 grit steel wool *some notes ----------------------------------------------- put a sealer coat of shellac on the wood right away, so it will have plenty of time to dry. It will help with LASER residue wipe-down afterward. don't try to glue it all at one time. apply the glue in stages before proceeding to next glue joint. the joints shrink as the glue dries, causing warpage of the box dimensions. by glueing in stages, you can adjust the box as you go along. don't leave much slack on the piezo wire going to the audio jack. it will hum and possibly slap the inside of the cabinet during use, which can be annoying. I did not glue the bottom on mine because I intend to add more piezo elements to other locations inside the cavity. I will use PVA glue and clamp it every 4 inches around the perimeter and allow 12 hours to dry. I suggest you do the same. If the humidity is above 70% for you, allow additional time to dry or bring it to an air conditioned environment for the final drying stage. if you want to make your box the easy way, try rahulbotics.com and look for the boxmaking app within his site. In total, from start to finish, this project spanned 3 full days. Most of that time was waiting for glue and shellac to dry between stages. Time spent actually laboring was about 9 relaxed hours with liberal self administration of beverages to stay hydrated...
