Kevin, If you don't want to push the machine to its limits or to have superlative performance, you only need to pre-tension the springs nominally (i.e. by hand). Otherwise, you can construct a stretcher. After my experience with horsehair and my new limited experience with sinew, I'd rather say that the stretcher was mainly intended for sinew springs, because after stretching, horsehair rope gives way and only recovers rather slowly, unlike sinew rope, which recovers quite rapidly.<br>
I advise you to use rather thick cord, followings Philon's statement. Dont trust Marsden's correction, he was wrong and mistook radius for diameter!<br>

It\'s all an accident, an accident of hands. Mine, others, all without mind, from one extreme to another, but neither works nor will ever.
