Andropenis

I want to construct a device and need to know which is the force that they exercise the wharves of the original device. Way of measuring it, it is easy with a kitchen weight. First it rests on the weight, this is only to know it’s weight, then there is pressed even the total compression of the wharves and the information is obtained. I will be grateful enormously for the information. I promise to send photos and instructions.

Traction devices use 600-1500 grams of weight
