Start off by determining the type of surface you want to use for the heads. You can choose from mylar, rubber pads or even window screen mesh, depending on your preference. For cymbals, you can use inexpensive plastic cymbals and attach rubber pads to mute them.
If you already have a Remo practice pad, here is how you can reconstruct it and wire it for sound:
1) First, take the Remo pad apart into pieces so that you`ll have the mylar disc and head, the foam disc and a plastic supporting base. Place the mylar disc on the foam and with a pencil, trace two 10-inch circles on the foam. Cut the circles out.
2) Carefully remove the plastic casing off your Piezo transducer. Scrape off all the silicone as you work and be careful not to damage the wiring.
3) Take around eight inches of speaker wire (20 gauge works best) and solder it to the Piezo transducer. Take the black ground wire from the Piezo transducer and solder it to the ground connecting end of the speaker wire, then take the red ground wire from the Piezo transducer and solder it to the positive connecting end of the speaker wire. When both transducer ends are soldered to the speaker wire, solder the speaker wire to the jack along the ring terminal.
4) Using your scissors, make a slit of about one inch inside the center of one foam circle. Then take an eight-inch metal circle (the lid of a large coffee can works perfectly) and score the center of the lid with a knife or scissors blade. Using a hot glue gun, glue the smooth surface of the transducer onto the area that you scored on the coffee lid. Then put the coffee can lid directly onto the foam disc that you made slits in and run the transducer wires out through the slit area.
5) Take the other foam disc and glue it on top of the metal coffee lid so that the lid is sandwiched between the two foam discs. Press down until the glue sets.
6) Take the plastic base and drill a quarter-inch hole between two of the spokes, then drill another hole between two more spokes and directly across from the hole you drilled first.
7) Work the wiring through one of the holes in the plastic base, then put the terminal ring onto the jack thread and wind it until it`s tight. Take the positive wire and solder it onto the jack`s center terminal, then do this with the other wire in the opposite hole.
8) Take the foam/metal lid “sandwich” you made and put it inside the plastic base. Put the practice pad back together and then place the drum head and rim on top.
Once you`ve assembled the basic electronic kit, you can accessorize it by adding plastic cymbals, toms or snares and even a kick pedal. Whether you look up ideas at we will rock you London or come up with a few of your own, you`re sure to think of a few one-of-a-kind additions for your kit. The beauty of making your own electronic drum kit is that you`ll have a truly customized creation, so use your imagination and add on as much as you want.
