Step 2: The Mouthpiece

PVC pipe comes with a variety of wall thicknesses.  Schedule 40 is common, and is what I used.  The 1/2" CPVC doesn't quite fit inside the 1/2" PVC, and the 1/2" PVC doesn't quite fit inside the 3/4" PVC.  By sawing a slit down one side of the pipe, it can spring open and fit tightly on the next size pipe down. 

My mouthpiece parts fit so tightly that no glue was needed. 

I cut the 1/2" PVC channel and put it in place to mark the size of the rectangular sounding hole.  Then I removed the 1/2" PVC, drilled the hole, and touched it up with an X-acto crafts knife.  You need a narrow and sharp blade to get in the hole and carve out the wedge-shaped edge of the hole. 

I put the wooden dowel plug right up to the start of the sounding hole.  Setting it further back toward the mouth changes the pitch and allows some tuning.  I used a metal drift pin and a hammer to set the plug inside the pipe. 
<p>how long is the part only with the finger holes?</p>
<p>You don't need to know it. You just have to make sure that when you play the note played is a C4 (523,25 hertz) with a tuner (you can download one on a smartphone for exemple, or on a pc a microphone).</p>
I haven't made any of these in years, and have none around to measure for you. Sorry about that.
<p>I don't understand how to make the mouth piece. I am doing a project for school. Will someone help?!?!?!</p>
It was going great until I connected it all together... When I blow on just the mouthpiece I get a nice, strong, sharp note, but when I connect the pieces together and try to play, it just sounds like air. Any idea where I went wrong?
I would use CPVC being that it's not considered toxic.
Has anyone tried to make this model with a wider diameter of PVC pipe?
I just made a &quot;great bass&quot; recorder with 1.5&quot; pipe. See my recent Instructable.
I thought I was doing well and successfully creating my recorder up until the point where I tried to play it. It sounds nothing like yours, it only sounds like air blowing through a tube...help?
It sounds like your air stream is not meeting the wedge of the sounding hole at the right angle, or the wedge is not shaped with an appropriate angle to meet the oncoming air. Play with the variables. <br> <br>Variables, like sounding hole size are easier to adjust by trimming off material than adding it on. I wouldn't even know how to do that, so maybe it is best to just start from scratch if that is the problem. Start holes on the small side rather than the large side, if you are not sure of them. <br> <br>It's a balance of a lot of factors. Play with them.
wow,sounds nice!
if i played that i would be gay
Made this yesterday and playing it today. Awesome :) I used a simpler style of mouthpiece (howtern's) since I couldn't find any CPVC and so used 1/2 inch PVC pipe for the body but it plays fine that way. I think that if a person could find different configurations you could swap mouthpieces between pipes to have different ones. Might experiment today.
The mouthpiece is the trickiest part. Having it swappable saves a lot of work for trying out the different pipes, once you get a mouthpiece you like. <br><br>Years ago, someone I knew was making shakuhachi bamboo flutes and I could never get a sound out of them. They are probably the simplest end blown flutes as far as fabrication of the sounding area goes. Lately I've been experimenting with making them out of PVC, specifically to fit my mouth and have been having a lot better luck. I still haven't got the necessary lip control for reliable playing, though. Recorder type mouthpieces take all that art out of it, along with a load of frustration.
sounds like a flute. cool!
That's awesome! Really nice sound and well played, too.
Thanks. Glad you like it.
any ideas for the other sizes of recorders?
I had a soprano to copy the finger spacing, hole size, and approximate pipe diameter. It would help to have a model for other sizes, too, but I don't have any others. I'm sure it could be done. <br><br>I don't think you can just scale everything up. For one thing, bigger air channels would mean more breath, and tiring out sooner. I would probably keep the channels and sounding holes about the same size as the soprano.
Wow that sounds wonderful!
Thanks. Making the object is just half the goal. The sound is what music is all about.
That sounds great! Yes I know you can get recorders for $2 and yours probably costs more, but home made is better. Thanks for posting it.
Yes, you can't really compare all things by dollar value. DIY is a fun game to play, and you usually learn something of use for later.
Very good work, thanks for sharing!
Thanks. Glad you like it.
