El,
I have been giving this a try and think you are right. Forging steel is my thought exactly. The glad seems to try to contract but can’t because of the trapped blood; consequently, there is a feeling of a deep stressing of the flesh. The unit gets very cold and numb, so be careful handling while removing the clamp. I have been warming immediately after removing the clamp by showering and jelqing (30-50). It takes at least three minutes in some fairly hot water in the shower to restore the body temperature. I am doing three sets per day on a 2 day on one day rest regiment. I have worked on several set-ups and now have one that works well, however, I won’t be drinking lemonade from that pitcher again. I will be working this for the next couple of months. I will report back. Be careful, because this technique does give the old boy a pounding.
