Step 1: How to make a ping pong ball gun

Are you tired of office/classroom/backyard wars without any stylish or efficient weapons?

Tired of getting shot with a cheap plastic bb gun that hurts like hell and breaks after 5 shots?

Do you want to shoot your colleagues/friends without having to worry about the danger off hurting them? Do you want to have a gun that will never break and requires extremely little maintenance?

Well then congratulations this instructable is perfect for you. Because today you will learn how to make a ping pong ball gun out of wood!

Allright so as I told you I will show you how to make a ping pong ball gun. I made this gun for classroom- and office-wars but as these guns will last a long while I can imagine that if I get kids even they can still enjoy these great toys :) I must say that I have had alot of fun with this gun and alot of people have already asked me to build them one to. I figure it's mostly because they are tired of getting shot with no means of returning fire but alot of people also admire the simplicity of the gun but at the same time the enormous amounts of fun you can have with it.

As you can hear I'm pretty proud about this gun. It has many advantages to it and almost no disadvantages. It's a great father son project or if your kids are to young to help just to make something  fun and cheap for them to play with. It's also the perfect weapon for any office- or classroom-war. As the name of the gun says it's a gun that shoots ping pong balls. So you really don't have to worry about any danger as a ping pong ball has never hurt anyone. So it's alot safer then a bb gun and is also alot sturdier. Where bb guns are mostly made from little plastic pieces which break easily and render the gun useless my gun is made from a solid piece of wood and all parts are found around the house making it easy to replace something in the (very) unlikely event something should get broken.

It's therefore my believe that this is the perfect gun for any child, teenager or adult who wants to have some harmless fun in the classroom, office or backyard.

Step 2: Materials and tools

For this project you will need

Tools

  • Sander
  • Jigsaw (powertool)
  • Drill
  • Hammer
  • Clamps
  • An adjustable workbench (or something else  you can clamp your  wood on and easily saw it)

Material

  • Wood 10cm / 3.9inch * 13.8 inch cm atleast and 2 cm / 0.8 inch thick (any wood will do, I actually used a pallet my dad brought home to use as firewood.
  • a Rectangular piece of wood. 15 cm / 5.9 inch * 2 cm / 0.8 inch and 1 cm / 0.4 inch thick
  • two eye-bolts
  • 4 nuts that fit on the bolts
  • 4 small nails or screws
  • A clothespin




Step 3: Making a sketch and drawing it on the wood

I had heard about ping pong ball guns before but I never saw one. So I decided to do a little research and then come up with my own design.

I quickly learned that a PPBG (ping pong ball gun) works like a crossbow. Using tension to drive an object forward (in this case the PPB). During my research I also found that many people drilled holes in their guns so they could stock extra ammunition. During my research I found no plans on the internet that where free of charge so I decided to come up with my own design. I took a piece of cardboard and started drawing away (pic 1).

As soon as I had something that looked okay and the shapes where conform with eachother I decided to give them distances. The way I did this was making my sketch conform. So the ping pong ball hole would be in the correct size toward for example the handle. I started from something I knew. I knew that the ping pong ball holes would need to be 3,5 cm wide as my ping pong ball was 3,5 cm wide. From there it was just measuring and check with your hand on the wood if it would fit right. (put your hand on the handle and see if you can hold it comfortably)

After that I decided to draw it on my wood. I started by drawing 2 straight lines from top to bottom I could use to make sure all the lines I would draw where straight. The first straight line would also act as the tip of the gun. I started drawing the lines from there using my ruler and the measurements from the sketch. (pic 2)

After a while I had my gun complete (pic 3). As you can see I made quite alot of mistakes while making my gun. I also changed some things like making the front piece wider so the ping pong balls would have more room and I could use part as a handle for my other hand.

So I ended up changing things from my sketch as I was making it on wood. But i don't expect you to figure this out all by yourself. Just download and print out the template of your choice (3,5 cm ping pong ball or 4 cm ping pong ball) that is included with this step, then trace it on your wood. The above information is so you know how I designed it and you can do the same when you want to build your own design.

Note: Remember to check the diameter of your ping pong balls before making this gun. Mine where 3,5 cm or 35 mm but I also saw 4 cm or 40 mm ping pong balls in a store. These will ofcourse not fit in the 3,5 cm compartments of your gun so you should take the second plan with holes for the 4cm ping pong ball. I also made the holes in the word document adjustable so you can choose to have less holes or holes in a different place. Just drag the holes, you'll see they can be changed.

A note on the template: Remember that this template fits the hand of a 20 year old man of around 1m95 in length. So use common logic and scale this template down if you are making this for a 6 year old. You can check if it'll fit by just scaling it down cutting it out and seeing how it fits in your childs hand. Also note that when you scale it down you probably can't have that much ping pong ball storage. (your pingpong ball holes will scale down to)






Step 4: Cutting the gun out of the wood

Okay so get your adjustable workbench out and make sure there is an open space where you can easily cut in. Then clamp your wood onto the table (pic 1 & 2).

I decided to start cutting out the bent shape on the handle of the gun because it's by far the hardest part of the gun (pic 2). Get your jigsaw (powertool) and slowly start following the line. The problem with this shape is that the blade of your saw is to thick to follow it in one time and not get stuck in other pieces of the wood. That's why you'll probably need to start cutting a new path once or twice so you can make bigger turns to match the line (pic 3) Don't worry if you can't get the shape completely right. Just leave some of the wood you can't get to on and then saw or file it down later.

Use this technique to cut out the rest of the gun. You'll want to often unclamp your wood and turn it to a better cutting direction. Do this but make sure the wood is secured at all times while cutting. Also don't stress if you can't cut on the line exactly. Just leave it and sand or file it down later like before. When you have completed this step you should have something like picture 6.

Now sand everything so it's nice and smooth. You'll probably want to spend some time on the curved shape we cutted out first. This will need the most sanding.

Note on the handle: As you can see on the pictures my handle is pretty long. This was something that was left from the sketch. As I didn't know what length would be good for my hand I decided to cut it out completely and then see how it felt in my hand. I ended up cutting off a part  since it was too long (pic 4 & 5) but if you are using the template this is of no concern to you as the handle is already changed there.






Step 5: Making the gun into a ping pong ball firing gun

After step 3 You should have something like pic 1.

Now it's time to attatch the rectangular piece of wood. But before we can attatch it we must cut a piece out of the gun so it will fit nicely.

So draw a piece of 2 cm / 0.8 inch length and 1 cm / 0.4 inch height as seen in picture 1 and cut it out with your electrical saw. (picture 2)

When you have done this take your rectangular piece of wood and cut it down to 15 cm / 5.9 inch in length.  You now have a piece of wood that is 15 x 2 x 1 cm or 5.9 x 0.8 x 0.1 inch. Then sand it smoothly and search for the middle. There you'll make a little hole using your nail so you can see where you must attatch it to the gun later on. (picture 3) You should now have something like picture 4.

Now make two holes as shown in pic 5 & 6 for the two eye-bolts to go through. Make sure they are in the middle and atleast 0,5 cm or 0.2 inch from the side. Then bolt them on the piece of wood by using one nut on the top and one on the bottom (pic 6). On the eyes of these bolts you will tie your elastic that will fire your ping pong balls.







Step 6: Drilling the ammunition holes

So I saw that alot of people had made holes in their gun to store ping pong balls. This is a great idea since you'll probably be on the move the whole time trying to avoid other peoples projectiles and keeping them in your pocket is not very handy for fast reloading.

Normally you should have already drawn out the holes on the wood in step 2 so now we need to cut those out. I suggest using a holesaw as shown on picture 1. I had one that was exactly 3,5 cm so I just needed to attach it and drill away.

Some handy tips and tricks you might want to use are:

  • To avoid having your drill slip and make the hole in the wrong place, premake holes with a nail so your drill can fit nicely in to it. This will avoid that your holes are not properly alligned.
  • Don't forget to clamp down your wood! Otherwise it will shift and your holes will not come out nice.
  • Don't drill from one side only. When you drill through the wood from one side only this will make the bottom of the  wood crack and ruin one side of your gun. Instead drill from one side t'ill the pointy drill part is trough the wood then unclamp and continue from the otherside (clamping the wood again ofcourse)

You'll know have something like picture 2. Sand the inside of the holes (use hand sandpaper) so the ping pong balls will fit in nice and smooth.

Note: My ping pong balls fit in the holes very thightly so they don't slip away during combat. However if your ping pong balls slip out of the holes you may want to consider nailing two nails on each side and putting a rubberband on them. These rubberbands will then keep the balls in place.



Step 7: Putting everything together

Okay so now use 2 small nails or screws to attatch the rectangular piece of wood to your gun. Make sure you nail it nicely in the middle. Make sure your nails/screws are not to long or they'll come out from the other side. You may want to think about adding woodglue on the bottom for extra support. I didn't do that and my gun works fine but on my second build I'll probably do it since it will be extra strong then.

When you are ready with that take your clothespin and dissasemble like shown in picture 3 & 4. then take the piece with the spring still attached to and nail it with two small nails to the gun as shown in picture 5. Then take the left over clothespin and attatch it back to the already nailed piece of clothespin like in picture 6.

Now you simply need to tie a rubberband on each of the bolteyes and you are ready to go shoot someone!








Step 8: Afterthoughts and creative possibilities

Creative possibilities

  • If your ping pong balls should fall out of the extra ammo holes, consider nailing two small nails on each side and placing a rubber band between them. The rubberbands will stop the balls from falling out. (explained in step 5)
  • it is possible to turn this handgun into a rifle or shotgun. Just lengthen the so called "barrel" making the rectangular piece longer and get a stronger rubber band. If you want to go for a rifle design you should also lengthen the stock. For a shotgun design don't lengthen the stock.
  • if your clothespin is not strong enough it may happen that the rubberband will slip out by accident. You can avoid this by putting a rubberband on the clothespin and gun so the clothespin is always pressed down.
  • you can paint your gun but I really like mine as it is so I won't. Also note that if you paint the gun your pingpong balls may not fit in the extra ammo holes anymore

Afterthoughts

Okay so this definitly was an interesting build for me and I hope it was for you to. For once I had very little problems during construction and I don't think you'll be faced with any problems either. But if you should have a question, comment, remark anything at all... Please leave a reply. I'm partly fuelled to make new great ibles by the response and views I get on already published ibles :)

The total cost of this gun is exactly zero dollars for me as everything that was used in this ible  was laying around my house. I think this will be the same for many people but if you should buy everything new, including quality wood (unlike my pallet wood) I guess you would be around 10-15 dollars or so. Note however that you can get the price down to 2 dollars if you use some cheap wood like I did. I recommend pallet wood because it is usually made out of strong wood as it has to carry alot of weight.

The funny thing is that by making this gun I shot so many ping pong balls all over the place I almost completely ran out of them. The fact that it uses PPB's for ammo and those are not always widely available is the only downside I can think off. Although If you are prepared with a few boxes of PPB you'll never even notice this :)

Also note that English is not my first language, it's my fourth... So if you should come across any spellingmistakes or weird sentences leave a reply and I will correct it as soon as possible.
