Step 3: Building the Base

The size of your base will depend on how many notes you choose to use. Mine ended up being a little more than six feet wide. With the two keyboard sections, I created two tiers, placing the one with the sharps and flats on top. For comfortable playing, your bottom tier should be as high as your hand when you have your arm bent at a 90 degree angle. I installed castor wheels on mine to make it more portable, to do this, I had to put 2 2x4's side by side on each side of the base so that there was a wide enough space for the wheels. Where the wheels were placed, it is extended out so the instrument does not easily topple.
<p>Hi, I just have one question! Where did the guy buy the white board that has all the holes from?</p><p>Thank you!</p>
Amazing instrument, thanks for the instructions! <br>I just have 2 questions, if you don't mind; <br>1: What did you use to fine-tune the PVC pipes? <br>2:where did you get those gorgeous paddles? <br>Thank you for your time!
To fine tune each note, I just used a digital tuner which basically just tells you if you're sharp, flat, or right on. You can get one at pretty much any music store. You can also download a tuner app to an iphone or iPod. As for the paddles, I purchased them from snubbyj. If you have watched PVC instrument videos on youtube, you have probably seen one of his. I just emailed him and asked him about his paddles. If you don't want to buy any, you can make your own too, just experiment with different types of soft materials. Let me know if you have any more questions.
Actually, what I was wondering is, when you fine-tuned, did you approximately chop out pieces of tubes, or did you use some kind of sand-paper to be really precise? <br>Thanks again <br>P.S. I might have other questions when I actually start building :)
I mostly used just the pipe cutter, at the scale of this instrument using sandpaper would not make a big enough difference for even the digital tuner to notice. If you want to make a small change just cut off around a quarter inch.
<p>what if you need to make the tube bigger again???</p>
How tall is it?
How tall is it?
How long is the total length. Also how long are the 2x4's.
<p>The speed of sound changes with air temperature. These numbers are for 72 degrees F.</p><p>https://docs.google.com/spreadsheets/d/1oP1tDTiKqxpraNtrazLQQFcmaE_Cu4iPdGQIA2cAImw/pubhtml</p>
Wouldn't a good idea be then to build in a way to &quot;tune&quot; the instrument if you so need to?
<p>When you actually started to cut the holes for the pipes in your frame, what size did you cut them? My dad says that the drills come in specific sizes and that the pipes might not fit if its too small.</p><p>Also, I read an article on the website &quot;Make&quot;: http://makezine.com/projects/pvc-pipe-instrument/ about a 12 year old kid who made this and he says that you put couplings through the holes of the frame. Have you done this as well? If not please explain how you managed to fit them tightly so that they could withstand vigorous beatings.</p><p>Thanks for your help.</p>
<p>If you use a 2 inch (outside diameter) pipe, you should be able to use a drill that is a 2 inch diameter as well. That way, the pipe will be able to slide through, but the coupling will not, holding the pipe in place.</p>
<p>Thanks for the help! Really appreciate it :)</p>
<p>Sorry I forgot to add:</p><p>What was the thickness of the pipes that you used?</p>
<p>How much ABS pipe did you use? <em>(Length)</em></p>
<p>how did you cut the holes out?? To put the pipes in?</p>
<p>I read that capping the ends of the pipes would require the lengths of the pipes to be half of that if they were not capped. Would that affect the sound?</p>
<p>Do they have specific notes?</p>
<p>How many different octaves did you use?</p>
how do I calculate the lengths of the elbows?
Where did you buy your ABS pipes? I live in Sweden and here they are very expensive, so I am looking to buy them somewhere else at a lower price.
Also how do you know what length of pipe makes what note?
Cardboard tubes would wear out really fast because you have to hit them over and over. As for the length of pipe, use this equation provided by Nate True <br>Tube Length (in) = (13300/(2*Frequency))+(Tube Diameter/2)
Do you think PVC sounds the best or could I use cardboard and get the same sound.
I was wondering how many pvc elbows/couplings you used? Where did you use the bore's? and what did you use the 2x10 for?
I used probably around 50 elbows, and the bore was to drill the holes for the keyboard. The 2x10's were for the side and bottom of the overall frame.
how did you calculate the tube lengths that were not in snubby j's list? did you use a formula? Thanks for the help
I found a formula online from a guy named Nate True. He gives this formula: <br> <br>Tube Length (in) = (13300/(2*Frequency))+(Tube Diameter/2) <br> <br>You can get the conversion from note to frequency here:http://en.wikipedia.org/wiki/Piano_key_frequencies
how much piping did you have to get total? my friends and i are doing this for a project and we need to know soon if you dont mind. thanks

How do you use sketchup for this? I have never used it before. Please help.
I don't really know how to help you. Just dive in and try it out
If you are going to build an instrument with the same proportions as mine and to compensate for any mistakes you might make, you should expect to buy at least 120 feet of pipe. Many times I accidentally cut a pipe too short and had to cut out a new one. I know it sounds like a lot but it all fits in there. I bought mine in 20 foot lengths and they aren't too expensive. <br>Let me know if you have any more questions, and how your instrument turns out. <br>Good luck!
What type of wood did you use?
I just used regular construction grade 2X4's and 2X10's bought from Home Depot. I think it's pine though I'm not really sure.
You mention that your paddles were purchased online. From where? I have searched and havent been able to fing any yet. <br> <br>Thanks, <br> <br>Dean
I purchased them from &quot;Snubby J&quot;, another person with his own pvc instrument. I had to personally email him and he sold me a pair for about $50. I was able to find his email address on facebook.
I am going to help my son build one of these instruments. Is there any way you could upload some more detailed photos of the wooden frame. Maybe a side view and details showing the center support. Thanks!
Thanks for the additional photos! That helps a lot. Thanks again for posting your project. <br> <br>Dean
I added some more pictures to step 3. Let me know if this works or if you need more details. Thanks!
Thanks for the suggestion, I'll get working on it. I'll let you know when I've added that information.
How many octaves are nessesary for playing most songs? I want to build a more portable version of this. Great instructable by the way!
My instrument has 3 octaves. So far, that has worked for me in most songs. 2 octaves would be cutting a little close and would limit you. 4 octaves would be ideal but would require a lot more work and money. Unless you have the time and money, I would recommend starting with 3 octaves.<br><br>If you choose you may also add extra notes to even things out. My instrument actually has 3 octaves plus 1 note so I have a C as my top and bottom notes.<br><br>Let me know if you have any more questions. I also want to know how your instrument turns out.<br><br>Good Luck!<br>
cool, thanks for your help
How much did the entire instrument cost to built
Mine ended up costing about $200-$300. Because of my lack of money though, it took me about 6 months to build. You can make a simpler a cheaper model though by having less notes and a cheaper base. Where I live, the pipe cost about $6 for ten feet. Lumber costs about $4-$6 depending on what size you get.
Wow, amazing instrument! Can't wait to see the video and hear you play it!
New Video! I've got more songs now!
