The official spud cannon of doom.
Potato guns: the underrated boom sticks of the DIY world.
These devices are used to launch small projectiles – typically potatoes – for long distances using a combination of combustion and compressed air.
Our design above is made with sturdy 4” and 2” PVC tubing, and it comes with all the necessary parts. The build process is simple, fast, and highly affordable. So if you’ve never built one, this design is a great place to start.
And of course, a must-have for anyone interested in backyard ballistics.
Ideal for: epic potato launching.
Ready to build your own? Great! Just check out the DIY build guide and diagrams below to get started.
Instructions
A note before starting-
Please understand - the below diagrams are genuinely and carefully designed to help you navigate the build process. However, we don’t include specific recommendations for which tools, hardware, and products to use, and so on. These truly are “DIY” designs.
We do, however, have a few generic recommendations for working with PVC.
Ready to build yours?
First up: the trigger assembly and fore-grip.
First, use the above diagram to gather all the pieces needed for this section.
Then, connect and permanently affix each piece, as shown above.
Once you’re done, go ahead and set this section aside, until it’s time to connect to the other sections later on.
Next: the barrel.
Use the diagram above to connect the pieces shown.
And please, take the time to make sure that your barrel is completely free of any obstructions, including any small pieces of dried cement and/or glue.
Once you’re done, set this section aside.
Finally: the stock.
This module should look similar to the last ones. Again, connect and affix the pieces shown above appropriately, before moving on to assembling your entire gun.
Almost done!
Now it’s time to put everything together. Your stock should slide neatly into your trigger assembly, which should in turn slide over your barrel.
Once everything is together, PLEASE make sure that all your pieces are permanently connected to each other, and that all your materials are solid and cured before putting your potato gun to use. We wouldn’t it to come apart the first time you fire it!
All done? Congratulations!
We hope you sling some truly great spuds!
