Hey, I recently built the Knex 6 foot ferris wheel and thought I'd share it with everyone.
Please note that many of these blue rods can be changed into red rods to conserve pieces! Ok, Lets start!
DISCLAIMER: IN NO WAY DO I TAKE THIS AS MY OWN WORK, THIS IS ALL KNEX'S. I ONLY SCANNED THESE INSTRUCTIONS TO SHARE THEM WITH ANYONE WHO WOULD LIKE TO BUILD THIS GREAT MODEL.
Step 1: Base- Part 1
Build Both Twice! We will call them a and b.
Step 2: Base-Part 2
Build this once!
Step 3: Base-Part 3
Step 4: Build the motor itself
Put this in Step three
Note: If you have a different type of motor, replace the white gear on the axle with your motor. I used the 6 volt motor. You could try other ones but i can't ay for sure if it will work. I'll test it out later
Step 5: Putting together Front side
Connect Step 1,2, and 3
Step 1A/Step 2/Step 1B
Step 6: Putting together the motor side
Step 1B/Step 3+4/Step 1A
Step 7: Connect the two!
Ok, now connect step 5 and 6!
Step 8: First set of Supports!
Build each of these Twice. Well call one of them part F and the other G
Step 9: Connecting F and G !
Now add these to the base like so...
Step 10: Build and Add the cross braces!
Build this twice and add these like so!
Step 11: Second supports !
Build each of these twice and connect em!
Step 12: Top Arch !
Build the archs twice.
Then, to build the axle, use a metal rod from your hardware store. Check the thickness with a knex rod. It'll cost no more than a dollar.
Step 13: Part one of the Wheel!
Look at anotations-
Step 14: 2nd layer of the wheel !
Build this 96 times-You dont have to do all the fancy stuff with the green connectors- i just used a yellow or orange connector where the white one goes. It worked for me.
Step 15: Third and final layer!
Build each of these 24 times: the difference is that one has two gray connectors and the other does not.
IMPORTANT: IF YOU WILL NOT BE ADDING SEATS TO THE WHEEL, DO NOT ADD THE GRAY CONNECTORS. JUST BUILD 96 OF THE ONES W/O CONNECTORS.
Step 16: Building seats !
If you want to build seats, build knex's seats. Build 24 times, and attach the white rods to the gray connectors from before!
