Step 1: STEP 1: Gather Your Materials
Step 2: STEP 2: Drill Air Holes, Attach Flanges
Step 3: STEP 3: Attach Ball Valves
Step 4: STEP 4: Measure and Cut 3 Pipes
Step 5: STEP 5: Make the Reed
Assuming you got a good sound, now it's time to build the little air flaps which will give you a strong sound even with a soft air flow. I made mine out of aluminum and welded it on but a good glue will work too.
Drill into your pipes on the back, approximately 4" up, and add a 1" long flat head screw to secure the reed.
Step 6: STEP 6: Support the Pipes
Now comes the tricky part: six inches from the end of the pipe, cut, saw, file, or grind a 3/8" wide hole across the top of the pipe perpendicular. Make sure it's straight. Use a 4" grinder and start out 6 in away from the hole and move towards the hole taking away more material as you get closer to the hole. File and sand away the excess material.
Step 7: STEP 7: Make the Bellows
If you're still reading this and haven't blinked, youâre either the world champion stare contest winner or you really want to build a pipe organ chair. I salute you.
The leather bellows: cut out your piece of leather so that it wraps completely around the seat part of your chair. Make it tight and then sew it together. I attached the leather with some glue and used thin strips of aluminum and wrapped them around the seat. This is to permanently hold the leather in place and ensure no leaks. I used 1-inch round head screws and drilled evenly spaced holes about 1 1/2" apart. Next I made a leather gasket to go around the bottom of the bellows and glued it into place. This gasket stops the air from escaping.
Sand the area that you're about to glue the bellows to and then lay down a bead of glue. Place your bellows down and screw from the underside of the chair up into the bellows. I used 2" course thread drywall screws because the bottom of my chair was thick.
Step 8: STEP 8: Finishing Touches
When you get up off the chair, the bellows inflates itself! By now, you'd probably like to take a seat. With occasional music. Turn the valves to play different tunes.
