With this instructable I'll try to show an alternative way of building a k'nex tower then the well known square shape.
This guide consists of the next parts:
Building the basic shape (steps 1-3)
Building the base of the tower (steps 4-5)
Strengthening the structure (steps 7-9)
"Getting it up" (step 10)
my towers (steps 11-13)
This is my first instructable so it isn't enything overly special but yet I found it something interesting to share, I add or change certain sections at times if i come up with extra information or if i find errors.
Most of the images are a bit cutted at the sides (that's why the odd shapes) and are reduced in file size (less sharp).
Step 1: Building the the basic shape I
To start off, use a connector like the (old colors:) yellow or white one.
Take one type of rods as the length of the 'tower' and the bigger rod as diagonal.
To make a first shape of the tower, make three of these.
Step 2: Building the basic shape II
put a connector at the bottom/top side (place where they are not yet connected) and connect the diagonals with it to get the shape as shown in the image.
Step 3: Buidling the basic shape III
Repeat this step multiple times and you'll get some nice tower. (While the size also depends on what length of rods you chose in step one)
Step 4: Building the base of the tower I
Doing this at all 3 edges will give some stability.
