Vacuum Canisters & Flow Control

I built a few Vacuum Canisters that still need to be leak checked.
Since they are sealed at both ends (disposable), I weighed and marked the Empty and Full weights as reference.

The larger one will go between the part and the VacMobile while the small one(s) will be inserted into the reverse pull line.

The Reverse Pull line is referred to as the "Supplementary Vacuum Line" in the VacMobile Diagram:

I also found these small pinch clamps over at Amazon.com

They won't completely pinch off the resin intake line, but they will do a great job at throttling the flow.
