A DIY Net Gun To Catch Whatever You Want



Suspicious drones hovering about your property? Burglars or other ne’er-do-well test subjects giving you trouble? Need to catch a dog that keeps meandering through your workshop? [William Osman] suggests you build yourself a pneumatic net gun that can shoot 20-30 feet to catch them all.

The net gun is built largely out of PVC pipe; the air tank — filled via a tire valve — uses adapter fittings to shrink it down to a 1″ sprinkler valve, with an air gun to act as a trigger. The net launcher is made of four lengths of pipe bent with the use of a heat gun — an Occam’s Razor solution compared to his first attempt — and is coupled to the end, while the net loads in using wooden dowels with washers as weights. It won’t trap any large game, but it will certainly net you some fun.

[William Osman] notes that you have to be sure not to mix up the corners of the net when loading or it’ll tangle itself up to the point of ineffectiveness, and to properly seal all the components to prevent lost off air pressure.

If a net gun won’t stop whatever is bothering you, a DIY railgun might do the trick.
