sound sample in mp3 below..
mixed in with guitars and other percussive and drone instruments..
1 - coconut ($1.75 at grocery store)
1 - broom stick or a 1 inch dowel.
2 -10 gauge guitar strings. used left overs.
1 - stick of bamboo
roll of string (used red nylon as stronger)
Small piece of left over plywood.
to stick it all together Glue. (I use sumo(brand) glue as it sets fast and bonds tight within minutes)
& other misc thing when it comes up.
total cost about 20 dollars max. Violin bow (bought the bow for 5 dollars a pawn shop).
Step 1: Coconut Sound Body.
Cut coconut in half, scoop out the coconut flesh then let dry (spoon works great)
After its dried (few minutes in the sun) we need to level it so the plywood rests on top evenly.
To achieve this glue some sandpaper on a flat surface (table) then with a circular motion sand the cut face of the coconut, till the all the edges are flat to the table. This is the most difficult step as it takes some patience. The outer husk hair also takes time to sand to a clean surface.
The photo shows a a different coconut half for an idea to work with. Also changed the neck rest on this project for better neck rest.
Step 2: Plywood Top
Step 3: Neck
Step 4: Glueing the Erhu...
To glue the plywood top to the coconut I had to trace out the necks girth on to the coconut. Then with a file i rasped it close to the shape of the neck but went a little over trace lines but works so lets move on.
After the hole was made. I glued the plywood top to the coconut.
Step 5: String Bridge and Hold Down.
B. Drill a small hole so that a guitar peg fits snug. this will hold the nylon string that hold the strings tension. (pic b)
Step 6: Tuners
Drill small holes on the neck end so the tuners fit. As they are friction holders it best that you slowly do so with constant checks.
Step 7: String Nut and Fret...
I was tring to find all the frets i had made for the instrument once but think they got chucked as i felt i could make better metal ones. But the the one shown is just a chopstick cut to length then tied with a loop under the neck. Which also can be placed along the neck for tunable frets. (Sitar concept)
Step 8: Last Words
Green twist... this is no over unity solar engine but who needs one when you've got music.
