+ | **Parts List and Sources: | ||
+ | A lot of the parts needed for these tutorials have been discontinued by Lego. As a result, they must be bought from mostly secondhand stores. At the time of writing these tutorials, these were the vendors I found to have the most stock of each piece available.\\ | ||

===== Construction: | ===== Construction: | ||
**Step 1: Pneumatic Cylinders**\\ | **Step 1: Pneumatic Cylinders**\\ | ||
+ | Place an axle 5 through the base of a pneumatic cylinder and secure it with a smooth 1/2 bush on each side. Place two notched axle 2's in opposite ends of a 180 degree angle connector. Use the axle slots on two axle/ | ||

**Step 2: Platform Foundation**\\ | **Step 2: Platform Foundation**\\ | ||
+ | Use the technic beams, pins with friction [black pins], long pins with friction [blue pins], axle 4's, and pin/axle connectors to build the foundation for the platform. This is the piece that the six pistons will be mounted to, and it will sit underneath the actual platform. The construction has been broken down into four substeps shown in the pictures below. | ||

**Step 3: Platform**\\ | **Step 3: Platform**\\ | ||
+ | The platform is based around a technic bush with three axles. Each axle will be built upon. First an axle/bush connector is attached to each axle with a notched axle 2 through it's other hole. Two 3 x 0.5 beams are attached to the notched axle. Two 4 x 0.5 beams are inserted in between the two 3 x 0.5 beams and secured with a pin with friction and a notched axle. At the end of the 4 x 0.5 beam an axle 4 is inserted with a pin/ | ||

**Step 4: Motorized Compressor and Switch Bay**\\ | **Step 4: Motorized Compressor and Switch Bay**\\ | ||
+ | Use the technic bricks, pins with friction, and a beam 3 to build the frame of the compressor and switch bay. Use the technic axle 6's, bushes with two flanges, and axle joiners to secure the six valves to the frame. Then connect the hosing in the fashion shown below. Finally, add the motor, air tank, and pump to the top with a platform. | ||
