Think up a good one and contribute to the evolution of the English language. mer side of the lever. It is entirely likely that I'll end up add- ing another set screw on the opposite side of the ferrule to let me use springs on both sides of the lever for additional control of both dampening and strength of stroke. The tension of the spring is varied by sliding the top end up or down the hammer arm. Yes, it's another "crude but effec- tive" moment. I made the springs in the shop by winding used guitar strings onto a rod, then doing a heat/cool cycle on them with a torch to reset the temper of the wire to the newly wound shape. (I've detailed the intricacies of spring-makin' in Chapter 4: look it up.) With unlimited springage at my dis- posal, I went the trial-and-error route on length/tension, and discovered that they are variables that are tough to predict. FWIW, my springs averaged 2½" long, and were formed around 8-32 threaded rod. Feel free to substitute rubber bands if you want to forgo the angst of coming up with suitable springs in suitable quantity. You'll achieve the same ends, without the steampunky goodness of coiled bits of wire. Enjoy "trial and error." It's another of those character-
