This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment I notice, when I am doing a weigh-off on a key board, that on some = actions as the hammer rises the acceleration is relatively slow and = steady. Other times, once the hammer starts to rise, the acceleration = is quite rapid. What is responsible for that difference? Friction = would seem to be the logical answer, but friction where? I heavily = lubricate actions before I do a weigh-off. There seems to be something = else at work in the geometry/leverage. Among other things, with the = rapidly accelerating hammer, it is more difficult to determine the = measured downweight. I there any way around that problem? =20 David Love ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
