Short Gun : Rubber Band

About: I am IT professional, living in Bangalore, India. As new gadgets come out everyday, we indulge in spending significant time and money on these gadgets. And our kids are learning from us, they know how to use...

Hi All,

I made my first rubber band gun, two weeks back.... and my son gave me a challenge to make another with 10 rounds...

So, in this instructables I will share how I made a 10 round, short gun using leftover wood and rubber band... This project is simple to make and in few hours you should be good to have a do a duel with your kid or friends

With this project I was able to reuse old wood and make a toy of it. and my son and his friends really enjoyed it. I hope to inspire more people to reuse and recycle..

Step 1: What Do We Need ?

Material

  • Wooden strip ( 3/4" x 10" and 3/4" x 8.5")
  • Wooden flooring leftovers from previous projects
  • 1" screws
  • 10 no 1" diameter rubber bands
  • 2" ( 4/16" or 6mm) bolt with nut ( I am not good in converting mm to inches )
  • Drilling machine
  • Jigsaw
  • Mitre box saw

Step 2: Design

This design is inspired by the simplest rubber band gun and a short gun.

I have attached reference design with scale

Step 3: The Handle

  • I used old wooden flooring (mdf), You could use a wooden plank as well
  • I used a jigsaw to cut these and I recommend clamping the wood planks to a table before cutting
  • Cut the handles as shown

Step 4: Barrel ?

  • I don't know what to call this part, I will just call it a barrel
  • We need to cut ten slots to hold the rubber bands at a distance of 10mm
  • I used a mitre box hand saw, Not all lengths were at same dept, use a matchstick to level these later
  • And give a rounded edge to the bottom one

Step 5: Main Body

  • Fix the upper barrel on the handle
  • Keeping distance of 6 mm to 7mm between them, fix the lower barrel below
  • This gap between upper and lower barrel, works as a channel for the trigger to move freely and in line

Step 6: Trigger

  • To give it a short gun's pump action, I used half rounded wooden strip
  • The trigger initially was made at 45 degree angle, later adjusted to 30 degrees
  • Using a 6mm bolt to hold left and right triggers
  • I added small wooden piece between the right and left tiggers, to guide it's movement within the gap

Step 7: Testing

Load the gun with 10 rounds of rubber band and test on a target

Future

  • add a motor and make this an automatic
  • auto load rounds
  • bigger
