Re: 177's Vacuum System

Didn't have a camera to take a picture but I'll give a short description.

We created a vacuum generator consisting of a globe motor, a large pneumatic cylinder, and a crank made from a large sprocket. By driving the cylinder with a motor and putting check valves on it in the proper arrangement we created ~25 in of vacuum. This setup weighed less than half the weight of the compressor.

We originally planned to use vacuum to pick up the big balls so we decided to use this system for as many other functions as we could. In the end we only used it to shift after we abanded big balls.

Pete
