Inspired by a do-it-yourself miniature table spotted on youtube we decided to built a full-size (122cm x 244cm) air hockey table. This instructable will guide you through all the steps in making this large air hockey table (without table legs).

You can download a 3D model of the DIY Air Hockey Table here. This will help you understand the project better. In order to view the 3D model you need to install the free application SketchUp.

We hope this information is useful to you and start building this thing straight away!
If you've got any questions or remarks or you just appreciate this instructable, don't hesitate to comment!

Step 1: Requirements and Measurements


Some of these measurements are standard european measurements. So if you are American these might vary a little. This means that you cannot make an exact copy of this project and need adjust the project to the materials available to you.

The drawings might clarify what materials you'll need. They show the basic construction and measurements.

Construction frame (of whitewood)

  • Two long sides: L=2530 ; W=45 ; H=70 (no. 1, see this component in the drawings)
  • Two short sides: L=1310 ; W=45 ; H=70 (no. 2)
  • Two long sides: L=2440 ; W=20 ; H=35 (no. 3)
  • Two short sides: L=1220 ; W=20 ; H=35 (no. 4)

Expenses: 27 euros (about $37,-)

Playing surface (of MDF)

  • L=2440 ; W=1220 ; H=6 (no. 5)

Expenses: 13 euros (about $18,-)


  • Small beams of scrap wood with heigth of 35mm (no. 6)

Expenses: 8 euros (about $11,-)

Plate opposite to the surface (of chipboard)

  • L=2440 ; W=1220 ; H=12 (no. 7)

Expenses: 11 euros (about $15,-)

Air source

  • Leaf blower, centrifugal blower or vacuum cleaner (no. 8)

How to calculate the the required volume flow and pressure rise: see attached PDF file below (I'm not sure if the specified jet speed is correct, though).

The required output for a 7 to 8 feet air hockey table is about 400 cubic feet per minute. Regular household vacuum cleaners have an average air output of around 140 CFM. You'd need at least 3 vacuum cleaners to make the puck float. This air source would therefore be to expensive. There are more powerful industrial vacuum cleaners, but are hard to get and expensive. Centrifugal blowers are highly specialized. The output ranges from a few CFM to a 1000 CFM or more. These blowers are used in air hockey tables as well. You might want to try to get one for cheap. Overall centrifugal motors are pretty expensive.

Leaf blowers are very powerful. Their output ranges from 350 CFM to 600 CFM. We believe that getting a cheap second-hand electric leaf blower is the best option. We therefore bought a new leaf blower with adjustable output (max. output: 490 CFM). We tried out the leaf blower at the lowest speed (7000 rpm) and it worked fine. The noise produced was significantly less than at higher speeds. It should have a circular outlet. The blower cost 40 euros (about $56,-).

Air inlet

  • One or two meters of tube with a diameter of about 90mm (depends on size of leaf blower outlet)
  • A sheet of PVC measuring 250mm by 250mm, with hole in which the tube fits. (no. 9)
  • If the tube doesn't directly fit into the hole, use a PVC muff (which does fit around the tube and in the hole)
  • Two pieces of plywood measuring 250mm by 250mm (no. 10 and 11)


  • Wooden beams with a length of about 400mm
  • Strong piece of fabric measuring 400mm by 400mm

Puck and Mallets


Note: these are the tools we used, but you might find that other tools can be used for the same job as well.

  • Proper tenon saw
  • Jigsaw
  • Regular saw
  • Hole saw
  • Wood glue (regular and polyurethane glue)
  • Drill with adequate drillbits
  • Dremel with adequate drillbits of 1mm (or 1/32)
  • Sanding machine with very fine and super fine sandpaper (P180 and P1200)
  • Hammer and suitable nails
  • Screwdrivers and suitable screws
  • Thermoplastic adhesive (hot glue)
  • Duct tape
Great Instructable. Built this guys for about $250 and it works great.
Great! Have fun with it!
Hi Guys thanks for a great instructable. I have built the table it works brilliantly. I made some slight changes (12v blowers from a camper van and an old desk for the base) We have had hours of fun. keep up the good work
Great! Great to hear you build one!
<p>How to Clean and Polish An Air Hockey Table Top</p><p><a href="http://www.airhockeydirect.com/air-hockey-table-cleaning.html" rel="nofollow">http://www.airhockeydirect.com/air-hockey-table-cl...</a></p>
<p>Blower 310 km/h is good?</p>
<p>Can a air compressor be used as a source instead of a leaf blower?</p>
<p>I don't know if i missed it or not but how is the air evenly distributed throughout the entire table? I didn't really understand how the leaf blower was hooked up to the table other than me knowing it was with an air tube.</p>
<p>I had the same thing in mind, and was considering that if it would be an issue, a PVC pipe manufold could probably do the job of spreading the air more evenly and even work as top plate stabiliser too.<br><br>However, i am currently looking into building one myself, and what materials i should use for the different parts and i am really considering to just use 8 PC fans added to 2 x 4 port channel fan speed controller, so i will have 8 adjustable fans working.</p>
<p>Because the holes are so small, the air doesn't directly escape though the holes above the air inlet. Instead, the air pressure is built up evenly throughout the air chamber. Please see step 6 for attaching the leafblower. I see that I didn't explain how the tube is connected to the leafblower. Well... I did it with duct tape at the time :). I think the best way to do this varies, depending on the type of tube and leafblower that you have. I hope this helps?</p>
Very helpful! Thank you for replying.
Is a 4x8 foot sized air hockey table an ok size? Or should it be smaller?
<p>8 feet is big standard length and only approved size for United States Air Hockey Association tournaments.</p>
I think it's okay. I believe it's the largest air hockey table size.
<p>Can the smooth side of hardboard work as a tabletop surface?</p>
It's quite rough, isn't it?...
<p>Hi, i made the air intel on the bottom wood (chip board) at the center, and used a bounce house blower. But when i turn On the blower, the playing surface (MDF) raises up because of the air flow fcing the playing surfce fom underneeth directly. I attached glued a 1.25kg weight on the playing surface inside the air room, in a way that it doesnt block any air hole. But it still raises up, because the air flow is cery strong. Any help would be highly appreciated.</p><p>Note:my plan is to lower the RPM of the blower, it runs on AC 240V. Any idea how to do that? Maybe a dimmer?</p>
<p>Did you try adding supports that connect the chipboard with the mdf board like in the instructable? I don't know how to lower the RMP of the blower...</p>
<p>We are going to build one for a school project, just asking if someone could help me with installing an electronic display for a points system or some sound on the table? It's for mechanics so we need to use some electronics in it.</p>
I've made a similar system with an arduino and two lcd 16x2 i can help you about that
<p>Would somebody who built this be able to tell me how long it took?</p>
<p>Amazing project, thanks for sharing! I'm trying to calculate my own table with fans (230V types). I found some large guys but I can't understand something in your pdf-file with the formulas. I'm trying to convert the formulas to metric units, as well. In the second formula, you've typed the following: D (hole) = (1/16)/12 ft. = 0.0052 ft. which, converted to metric units, is 1.58mm not 1mm (the drill bit you've used in this project). Is your calculation correct? Also - is there any relation between the inside volume of the table and the flow (In the manufactured versions - there is a prism in the table to reduce it's volume, for now - I don't know why)... Keep up the good work!</p>
Thanks for your comment! What formula are you referring to? I can't find it in the text. Can you tell me what step it is? It's been a while since I wrote the instructable. I can't remember that I calculated the drillbit size. I don't know if there's a relation between the volume and the flowrate. My interpretation is that the volume is not a critical dimension, and that the pressure throughout the table is the same. I could be wrong though.
<p>Hello again and thanks for the quick reply!</p><p>It's in Step 1 - <a href="https://www.instructables.com/files/orig/FRQ/9KFD/I21QZU62/FRQ9KFDI21QZU62.pdf" rel="nofollow">3-162.pdf</a>. You're right, the volume isn't critical (as a geometry) but it's a must to calculate the flow rate for the fan's motor. The rule I've heard is: less the volume - the better. Basically the theory behind the Air-hockey table is the hovercraft effect. I'm stuck on the part that I need to convert the velocity of the air thru the holes (worst case scenario is when the puck is on top of 4 holes, the best case - 8 holes) into a force. :)</p>
<p>Hi Guys, thanks for this tutorial. But, is it possible to have back the 3D model</p><p> ? Because it's not avaible anymore, same for the hole template. I've planned to make the table 40% shorter for a school project !<br>Thanks for everything, Keep doing awsome things </p>
<p>Thanks for letting me know. I've uploaded a new hole template. It's strange that you can't access the 3D model. Have you tried clicking the link? (<a rel="nofollow">http://sketchup.google.com/3dwarehouse/details?mid...</a></p>
<p>where can i find the sketchup plans? the link is broken, thank you!</p>
Mission accomplished just a few final touches but let me save the next person the headache u don't need the 150 pillars just use a peice of underlayment for the bottom and make sure u attach it to the 2 X 4 outer framing and ur good I used a bouncy house blower it works great
<p>Okay, nice! We just wanted to make sure that the MDF remains flat. Good to know that it works with less supports.</p>
Is it really necessary for the 150 some blocks of 2&times;4 I bought a sheet of underlayment for the bottom and figure only a few supports would be needed cuz it'd paper thin and light weight
Gonna try this got my 8 ft sheet mdf and frame to get started in don't see drilling 4600 holes going to well gonna take me at least 6 weeks wish I knew of a machine ship that can drill them all
I am actually making a smaller version of this now (2 by 3 feet) i know you had mentioned cfm in the instructions now i was wondering if static pressure matters also how accurate does the hole spacing have to be.
<p>At the time that I built the table, I didn't do any calculations in order to find the right air supply. Just now I did a quick search on the internet, and to my surprise I found this engineering exercise: <a href="http://user.engineering.uiowa.edu/~me_160/Extra%20Problems/Chapter3/3-162.pdf" rel="nofollow">http://user.engineering.uiowa.edu/~me_160/Extra%20...</a> It describes how to calculate the required volume flow and pressure for an air hockey table! I hope it is useful. I don't know if the values are correct though. A spacing of 25mm seems to be common. I don't think you have to worry about the accuracy of the hole spacing.</p><p>I also found this Popular mechanics article: <a href="http://books.google.nl/books?id=EuIDAAAAMBAJ&lpg=PA94&dq=Popular+Mechanics+air+hockey&pg=PA94&redir_esc=y#v=onepage&q=Popular%20Mechanics%20air%20hockey&f=false" rel="nofollow">http://books.google.nl/books?id=EuIDAAAAMBAJ&amp;lpg=P...</a> Less related to your question, but interesting anyway.</p><p>Good luck!</p>
Thank you very much for your help i actually just finished this and it works great i made my own mallets as well as 3d printed my own puck i also plan on adding a scoring system in the future.
<p>What is the average price for Home Depot? I'm thinking about doing this.</p>
<p>we made a air hockey table but we have a problem on it..we want the table the surface to be smooth.we paint an acrylic spray paint but the surface of the table is rough.what we're gonna do on it?</p>
<p>I would sand it with some fine sandpaper. Perhaps do several layers. Some tips on painting mdf to a mirror finish: http://forums.shoryuken.com/discussion/67501/how-to-paint-mdf-to-a-mirror-finish-worklog</p>
<p>Thank you for the instructable! Build it for 50 &euro;<br>I did a flipper also, you can have a look at http://benriollet.com/experimentations/arcade</p>
<p>wow, didn't see it until now. awsome :)</p>
<p>now if you have a spare refrigeration unit to pull apart you could make an ice version. </p>
I am building this table as a school project, a mini one (1mX60cm). I was just wondering how &quot;1&quot; and &quot;3&quot; fit together, and also how the sides &quot;2&quot; and &quot;4&quot; fit together? Can anyone help me?
I used polyurethane glue and nails to attach 1 to 3 and 2 to 4 (see step 2). I hope this answered your question. Good luck!
Awesome idea. I'm actually trying to make my own 6 x 3 version of this. But instead of using a leafblower, I am planning on using 8 40CFM computer fans (<a rel="nofollow" href="http://www.goldmine-elec-products.com/prodinfo.asp?number=G16778">http://www.goldmine-elec-products.com/prodinfo.asp?number=G16778</a>) They should add up to a bit over 225, which is the minimum CFM for a 6 x 3 air hockey table. But I'm not sure if this will work. Can someone help me?<br/>
Hey, I was wondering whether you have completed this project succesfully. Many people like to know whether they can use computer fans in their table. Thanks in advance!
I never actually attempted the project, so I'm afraid that I can't tell you about that. I did make a small version with a single fan, though, and it worked surprisingly well. I don't see why a scaled up version wouldn't work.
Yes it will, I bought a fan with 340 m&sup2;/h and 127 Pa pressure and it worked, the puck does not float as smooth as with the leaf blower but the noise, oh the noise, it is gone. If you play hard you will probably not notice the difference in smoothness. Here is the fan I bought, @Casvandegoor I can send you a video of the fan so you can upload it here for others. Anyway I bought the fan here, make sure you buy another piece of crap along so the total price will be over 50 euros, you can google a couponcode for getting 5 euros of from orders above 50 euros :) Shipping is free above 25 euros, but I don't know how it works for people ordering from outside the Netherlands. <br> <br>http://www.conrad.nl/ce/nl/product/189493/Ventilator-172x150x51mm-230V-IP55/SHOP_AREA_17202&amp;promotionareaSearchDetail=005
Thanks for your comment! I could embed the youtube video into the instructable?
