This is an elastic gun I made a few years back to deal with those pesky mosquitoes that sit out of reach on the wall and on ceilings! When I was a kid I had a plastic toy gun similar to this that used to shoot elastic bands, and a few of my friends did too. It was a lot of fun to play ‘cops and robbers’ etc with toy guns like these, that shot elastics with enough force to sting without causing any harm! Of course, we wore sunglasses to protect our eyes, so if you want to make this to play games with, it’s a good idea to consider eye protection first. As I mentioned, I made it to show those cheeky blood suckers that land out of my reach a thing or two, and it was actually quite simple, as you will see!

The body of this item was made from off-cut bits of pine. A slot was cut vertically through the part intended to house the trigger.

The trigger was cut from a piece of steel flat bar with an anglegrinder, and rounded off and smoothed on a bench grinder. A hole was drilled through the center for a mounting screw to go through. The top part opposite the trigger end is notched to hold the elastic band. When the trigger is pulled, the upper end drops and the band is released.

I cut a length of the handle from an old feather duster to make the simulated barrel, and hammered a small nail or panel pin in the end to retain the other end of the elastic band.

I used another shorter length to make a front end handle and drilled a hole under the forward part of the main barrel to fit it into. Then I made the handle, which was just a rounded rectangular piece screwed onto the body behind the trigger.

The vertical slot cut for the trigger needed to be along the center line of the body, in line with the back of the “barrel” to ensure the aim would be as true as possible. The slot also needed to be just wide enough for the trigger piece to slide into and move about unrestricted, but without wobbling. The top end with the slot needs to protrude out the top so that the elastic can reach it. A small hole needs to be drilled through the top as well, beneath the slot for the rubber band, so that you can insert two small springs – the springs are to keep the trigger in position when the elastic is on, otherwise the device will immediately release the elastic – or when you least expect it!

The last thing I did after firing off a few test shots, was to paint it black. You don’t have to paint it of course, but I felt like it!

Pictures included – enjoy!
