Knex Modified Chain Stepper Lift

Hi everyone.
     This is another version of a stepper lift. As you can see from the video and pictures it is quite tall and can be made even taller because there is not a lot of friction. I used two regular knex motors to power this lift but one electric plug-in knex motor should do the job, but you'll have to change the gears around. Enjoy the video.

• green - 76
• white - 116
• blue - 200
• yellow - 128
• red - 165
• grey - 53
• tan roller coaster - 1
• large bendy - 5*

• grey - 65
• light grey - 50
• orange - 34
• red - 54
• green - 87
• yellow - 85
• white - 21
• purple locking - 120
• blue locking - 47
• orange roller coaster - 52

• thin small wheel - 1
• thin medium wheels - 14
• thin small tire - 1

• small gears - 2
• medium gears - 13
• large gear - 1

• small triangle panels - 5

• Y-clips - 95*
• blue clips - 12
• tan locking clips - 12
• roller coaster clips - 2*
• washers - 2
• blue spacers - 83*
• silver spacers - 34

• blue hinge halves - 2
• motors - 2 regular or 1 plug-in
• chain links - 134
• roller coaster track length - 2 pieces 80"(2m) or 4 pieces 37"(94cm)

*The large bendy rods are optional.
*You will not need to use a lot of Y-clips if you are using thick roller coaster track.
*You might need extra roller coaster clips at the top part of the steppers.
*You will not need to use a lot of blue spacers if you are using thick roller coaster track.

     For this step you will be building the base and a bit of the gears and entrance.

     The steppers themselves were kind of hard to photograph, so be sure to read the image notes. I broke the steppers into two parts, the lower and the upper. The lower part uses 21 chain links and the upper uses 18.

The narrow steppers are almost the same as the wide steppers, but narrower. I also broke them into to parts. This time though the lower part has 18 chain links and the upper part has 21 chain links.

You'll have to change the gearing mechanism around if you are using a electric plug-in motor. (which I highly rec-amend)

Great! Now you're done. Hopefully it works well in your ball machine.
