Construction
Step 1:
Using four of the pins with friction, attach the two 1×14 bricks to each other. Attach the axle pins and the remaining two pins with friction to the outsides of the brick in the holes depicted.
Step 2:
Attach two of the 3x3x0.5 beams to one side of the bricks and use and axle pin to attach a pneumatic cylinder with the ports facing away from the bricks. Mirror the beam and axle pin structure on the opposite side as shown for stability.
Step 3:
Connect a pneumatic valve to the remaining pins with friction. With the valve switched to the left side, attach an axle joiner, a notched axle 2, and a 1×2 cross block to extend the lever to the heigh of the cylinder.
Step 4:
Using a long pin, connect the cross block to the pneumatic cylinder so that the switch may be controlled with the expansion and contraction of the cylinder.
