WHAT YOU’LL NEED

  • 1″ x 4″ board, 24″ long (actual size is 3⁄4″ x 3 1⁄2″)

Cut the board as follows:

  • 3⁄4″ x 3 1⁄2″ x 16 1⁄2″ board (body of launcher)
  • 3⁄4″ x 2″ x 7 1⁄2″ board (crosspiece)
  • Spring-loaded wooden clothespin
  • Coping saw (for cutting curves)
  • Crosscut saw (for cutting across the wood grain)
  • Ripsaw (for cutting with the wood grain)
  • Sandpaper
  • Drill
  • 2 1⁄4″ eyebolts, 2 1⁄2″ long
  • 4 1⁄4″ washers
  • 2 1⁄4″ nuts
  • 2 1 1⁄4″ wood screws (for crosspiece)
  • 2 1⁄2″ small wood screws (for clothespin)
  • Drill bit (sized for pre-drilling 1⁄2″ wood screws)
  • 1⁄4″ drill bit (for eyebolts)
  • Drill bit (sized for pre-drilling 11⁄4″ wood screws)
  • Countersink bit (so driven screws are flush with wood surface)
  • Rubber band(s) (about 1⁄4″ wide)
  • A pocketful of pingpong balls

WHAT YOU’LL DO

pingpong-11. Cut out the body and crosspiece of the launcher and sand both pieces. Follow the dimensions shown above.

 

pingpong-22. Drill holes in the crosspiece for the eyebolts. Drill and countersink the two holes for the wood screws that hold the crosspiece to the body.

 

pingpong-33. Screw the crosspiece onto the body.

 

pingpong-44. If you can’t find a rubber band long enough for the launcher, you can loop several smaller ones together.

 

pingpong-55. Loop the rubber band(s) to the eyebolts.

 

pingpong-66. Attach the eyebolts to the crosspiece using the washers and nuts.

 

pingpong-77. Take apart the clothespin and screw the bottom half to the body. Be careful to drill and countersink these screws so you don’t split the clothespin. Reassemble the clothespin.

 

pingpong-88. Load a pingpong ball and you’re ready to launch. If the clothespin is to weak to hold the rubber band, wrap another rubber band around the gun to strengthen it.

Cardboard or plywood makes a good target. Don’t forget to wear safety goggles.

    I’ll make a handgun version. Cool idea boys life people!

  11. Scremintal says:

    I think using a loose rubber band on the clothespin will allow for a more trigger-like release from the bottom. Golf balls seem like it would be more efficient.
