Tip: You can use any size gears for this build!
Rack and Pinion
Rack and Pinion
Tip: The green sliders are attached to the base plate. The metal bar will slide back and forth with the rotation of the gear. Use the tiny screws (gold or painted top) to attach the rack to the metal.
Crank and Slider
Crank and Slider
Tip: Make sure the metal piece allows the green slider to move BEFORE attaching it to your build. Use a spacer on the Cam so the metal bar can rotate freely.
Belt Drive
Belt Drive
Tip: Use a little tape on the back of the pulley wheel so it doesn't spin freely on the axle.
Differential
Differential
This build will need bevel gears inside of the differential.
Blue Team Builds
Worm and Wheel
Worm and Wheel
Tip: The use of bearing flats help to secure the worm at the right height for the wheel. The two side pieces are angle gussets.
Lead Screw
Lead Screw
Tip: Make sure the bottom metal piece allows the green slider to move BEFORE attaching it to your base plate
Cam and Follower
Cam and Follower
Tip: You may need to adjust the height spacing on this build so the follower goes up and down smoothly. The gray piece should be spaced off the build with a small spacer.
