Things You'll Need:
- 3/4-inch white PVC pipe
- Ruler or tape measure
- Hacksaw with fine-toothed blade
- Files
- Drill and drill bits
- Clamps
- Pencil
- Cork
- Masking tape
-
Step 1
Purchase the PVC pipe in a hardware or big-box home improvement store. They usually come in long lengths, 12 feet or more, but you may be able to find a smaller piece that has been discarded.
-
Step 2
Stores will usually cut the pipe to your specifications. Cut about a 2.5-foot piece.
-
Step 3
Smooth the cut end of the pipe with a PVC file. Make sure that the end is straight (no saw or cutter marks) and smooth.
-
Step 1
Using the tape measure or, preferably, a ruler, measure for placement of finger holes and embouchure. To avoid making marks on the flute (which can be erased later anyway) you can place a piece of tan masking tape on the pipe.
-
Step 2
Starting at the "bottom" of the flute (the end opposite the embouchure), measure finger hole placement in inches as follows: 3.85, 5.39, 6.53, 8.77, 10.24, 11.70 and 20.67. The final hole is for the embouchure.
-
Step 3
It's easiest to drill the holes in a straight line, and this is how beginners should do it. Later, if you want to drill offset holes, just make certain the distances from the end are the same.
-
Step 1
Support the pipe by placing it between two pieces of wood -- such as 2 by 4s -- which are securely clamped to your work table.
-
Step 2
Use a nail or a hole punch to create starter holes. This is so the drill bit doesn't slip and ruin your piece.
-
Step 3
Drill the holes using the following drill bits: 1: 5/16 inch, 2: 7/16 inch, 3: 3/8 inch, 4: 5/16 inch, 5, 6 and embouchure: 3/8 inch.
-
Step 4
Use a small file to cut a slight wedge in the embouchure hole, on the side that will be against your lip. This will allow for a better tone. Use the file to smooth out the other side.
-
Step 5
Finish the other holes by gently filing them until the surface is smooth.
-
Step 1
Use a piece of cork that has been filed to just fit in the embouchure end of the flute. Using a dowel, insert the cork into the embouchure end, and tune with a piano, or another instrument to the note "D" which is accomplished by covering all the finger holes.
-
Step 2
Tune to higher octaves, adjusting the cork as necessary.
-
Step 3
Trim the exposed edge of the cork once you have the proper tuning.
