RE: Wax as a "lubricant"? (bow setup)
Waxing the bowstring is necessary for a number of reasons. First, under high magnification, the fiber make-up of the string is visually different from what you may think. Millions of extremely fine fibers going in many directions make up a single strand. The general flow is unidirectional lengthwise with a clockwise twist. All those millions of fibers need a lubricant between each other in order to not create friction or any other force to compromise their integrity. The more unidirectional fiber flow, the better the string. Regardless, the lubricant must be present. That is the reason for the wax. A barrier between fibers is always present yet also holds them together and their total strength is enhanced. With our high-tech world, wax is still the best material for this purpose.
