Proper Evacuation Techniques with Jim Bergmann

So the last video we showed what we can do, now I thought some of you might like a better understanding of what we are doing and why it works.  I hate to say it but most of us have been doing evacuation wrong our entire careers, myself included. It was much later in my career when I started to do it right, and a lot of research and testing to perfect the techniques.  Evacuation is not easy. Personally, I still learn more about vacuum almost daily. So here is an opportunity to learn from my mistakes which have now become my experience. If you follow the instructions outlined here it will make things a lot easier.
