I will be showing you how to make a K'nex cross bow
that will shoot a 2 1/2 ft arrows or knex arrows nearly through card board.
*4 rubber bands
*2 large wheels
2 blue stubs (see step 1)
2 grey stubs (see step 1)
*2 Dark blue
1 red conector
5 orange conectors
1 blue rod
3 grey rods
Step 1: Assemble Triger
this is the only place you ned to use the dark blue conector
( i only used them every where else because i had no more white conectors)
Step 2: Build the Rest
Srry this picture is upside down.
Step 3: Making the Limbs
Step 4: Ataching All 3 Parts
Step 5: Fully Completed
Step 6: The End
The arrow and rubber band sits where you see it.
When you pull the triger it pushes up and out the rubber band
the 2 sticks are for when you are loading it so when or if the arrow and rubber bmake sure they will stop the rubber bandsand slips out, these will make the arrow shoot only 2 ftmake sure the 2 rods stop the rubber bands
making knex arrow:
atach pieces where the red conector is the tip then grey rod, orange conector, grey rod, orange conector, grey rod, orange conector blue rod and last orange conector.
