Introduction: Automatic K'nex Hidden Blade (for New People Like Me)
this is a modified version of another hidden blade i saw, made by Raz1r Knex Bull3t.
i made it automatic by means of rubber bands, i made a finger trigger, and put a cardboard vambrace on it, so you can take it of and put it on quickly.
this is a simple blade for new builders and builders with a limited amounts of k'nex.
Step 1: Materials
the materials are:
5 long gray rods
7 orange connector pieces
3 red three nook pieces
5 gray two nook pieces
11 gray one nook pieces
4 pink short one nook pieces
4 white rods
1 tinny green rod
3 blue rods
some rubber bands
some string
some card broad
scissors
a finger sized ring
a nerf bullet (optional)
Step 2: Bacis Part One
take 2 of the gray rods and join them together with 2 orange pieces
put another rod in through the orange pieces and secure it with the end of a nerf dart and a 3 nook red piece
now put on 1 nook pieces on top next to the dart and tie a rubber from them to the 3 nook red piece
now it should pop back into place if you push it down
Step 3: The Base
take the other 2 gray rods and put pink pieces on the top of both of them an then click on 2 nook pieces, an orange concocter, and then 2 2 nook pieces again.
slide the first piece uoy mad into the 2 pieces om top of the one you just made and put two 1 nook pieces on the end to allow it to slide back and forth
Step 4: Riging the Rubber Bands
you can now attach orange pieces on the end of the gray rods and put rubber bands throgh them and put a blue bar over them to hold them on place
you can then rig the bands to the pink pieces and it should work like a spring now
Step 5: The Triger Pice
you should be able to just copy the picture for this one
Step 6:
attach the piece that you just made to the rest of the device
the 2 nook piece should lock into the red piece on top (see second picture)
Step 7:
make 2 of these and strap them onto the end of the mechanism with an orange piece to tie them down
these will hold the string to attach to your arm in the later
Step 8:
make what is in picture one
tie put the string through the orange conecters on the bottom of the device and tie the end to the triger
Step 9:
now you should have something that looks like this:
all you have to do now is put string on it an strap it to your hand
i said that i would explain a vambrace but i am to tiered. maybe later
