This was my first pneumatic. I always wanted to try. I actually did 2 this year. I have a skeleton reaper that lies flat on the ground then rises to 6 feet tall. I found a pneumatics pdf on this site and simply followed it. If you do it, make sure to get the 110V solenoid's should you decide to wire them to a motion sensor. I ordered everything on Ebay except the cylinders.Great job! I always wanted to get into pneumatics. Maybe next year?
