Almost all 20-note street organs use the same notes. This makes it easy to find music. The 20 pipes play these notes:
You should have some basic experience using common woodworking tools, and be comfortable reading directions, taking measurements and assembling and gluing parts.
You will need to supply the following: PVA woodworkers glue, contact cement, super-glue, fast setting epoxy, shellac (fresh) and additional paints, stains or varnishes to decorate the case as you desire.
You will also need to own the following tools: Metric ruler, pencil, square, assorted clamps, clothes pins/pegs, pliers, screwdriver, hammer, razor knife, sand paper, drill with assorted bits, small soldering gun, masking tape, rubber bands, scrap cloth for cleanup, paint brushes, scissors, powdered graphite, synthetic grease and a few other common items.
The entire kit comes complete in a 11kg box measuring roughly 32x32x42cm. This includes 20 organized bags of various parts (screws, nuts, washers, gears, rods, cloth, nails, etc). It also includes 23 tiles of laser cut wood, wooden molding, metal shafts, plastic tubing and other bits and pieces. You also get a detailed manual with all steps described and illustrated. You need only to supply the glue, some tools and time. Please see the photos page for a picture of the complete unassembled kit.
It really depends on your dedication, skill and available time. Some skilled workers have finished the kit in a week. If you only have a few hours on weekends, then it could take several months. The average constructor spends 30-50 hours building the kit.
