How to Make a PVC Ocarina

In this instruructable you will learn how to make a PVC ocarina!
From wikipedia;
The ocarina ( /RkY�rument.[1] Variations do exist, but a typical ocarina is an enclosed space with four to twelve finger holes and a mouthpiece that projects from the body. It is often ceramic, but other materials may also be used, such as plastic, wood, glass, clay, and metal.

I have searched high and low across the Internet and found no instructions on how to make an ocarina other than clay.
So as far as I know this is a first so bear with me.

here is a vid of how it sounds.

Materials:
(1) 6" piece of sch 40 1 1/4" PVC
(2) 1 1/4" plugs (I had to use a reducer and a plug)
Possibly CA glue ( crazy glue) , I didn't need it

Tools:
Sand paper 100 and 220
steel rule
unibit
various files
pencil
saw
1/2" & 1/4" chisel
unibit or drill bits
drill

 cut the flanges off of the plugs, or reducer in my case (and put the plug and reducer together if you needed to get both)
And yes clean up the cut part with a file or some sand paper.

make a mark on the pipe the same size as the plug.

right behind where you made the mark, draw a rectangle 1/2" X 1/4" and 1/2" X 1/2" behind that.

using the 1/4" and 1/2" chisel (or power tools) cut out the 1/2" X 1/4" rectangle
then make the 1/2" X 1/2" square into a ramp with the apex at about 1/64"

first mark a 1/2" wide path on the plug
then use a chisel or 100 sandpaper or a file and file the side that you drew flat (indicated by the red lines), it should be 1/32" deep
then about 1/2" down carve a deeper ramp as indicated by the blue lines and red arrows.
then sand with 220 to make is smooth

with the narrow (1/2") wide section inserted first into the pipe with the fipple cut into it.
Align the end of edge of the plug to the edge of the of the fipple opening. I have a attached
a crude cross sectional drawing with the pipe in black and the plug in purple red and blue.
Once you have done this you can blow into it and you should get a tone.
I fitted the plug and the plug was snug I didn't need glue to make it work.

this is where is get a little complicated. I know very little about music so bear with me.
for the rest of the instructable you will need a tuner. there is a nice one to use for free
here: http://www.seventhstring.com/tuner/tuner.html
next put the other plug in the opposite side.
with the tuner on push in the plug and blow into the unfinished ocarina until you get a "C" with the little blue arrow at the bottom as close to "0" as possible.
If you a get a funny little "b" that is flat or a pound symbol "#" that is a sharp.
(for the purposes of this instructable and for those who don't know about music)
While trying to get a "C" if you get a a flat (funny little "b") the tone is on the low side push the plug in. If its a sharp (pound #) pull the plug out till you get a "C" on the tuner (with the little arrow at the bottom as close to 0 as possible.

Again this is complicated.
A little more on music so bear with me.
(for the purposes of the instructable)
music notes start with a C, then D,E,F,G,A,B and the next C up.
This is called an octave (8 notes).
If you did everything correctly you should be getting a C5 on the tuner which is
one octave above middle C (C4, middle C is the middle C key in a keyboard)

Thing to keep in mind while drilling your tuning holes, start with a small hole and increase the size until you hit the desired note.

The holes are #1 top right, #2 bottom right, #3 top left, and #4 bottom left.

Start with the #1 hole and start all holes small and keep going up in size till you hit a D note.

Remember to clean the holes with an Xacto knife and 150 sandpaper after drilling.

Then continue with hole #2. To tune #2 you have to cover #1 (the one we just made) keep going to you hit an E note .

(you get an F by leaving 1& 2 open incase you were wondering)

Now the #3 hole. To tune the #3 hole you must cover the #2 hole and leave the #1 open until you get a G
.
For the 4th and final hole you can cover hole #1 and tune for B or leave them all open and tune for a C.

Just a side note for the high C in my ocarina I have to blow hard or I get a high pitch whistling sound.

That's it!!!! Your done!
If you like you can spray paint it.
Here are some sites that contain ocarina tablature ( sometimes called fake music).
It shows you where to put your fingers to play a song.
