</div></blockquote><div><br>Will -- a bit of nitpicking here, but the load has not changed; what has changed is the intensity of the force (higher) and friction owing to the smaller carrying surface area of the jack top. Your argument still theoretically holds, however.<br>

</p></div></div></blockquote><div><br>Whether the rep spring wire gage is heavy or lighter, the same force from either will be required to raise the hammer in the manner that most of us agree on and with a concomitant and beneficial effect to the jack behavior as well. "Too heavy" a gage, as I recall with my set, behaves exactly as you say, making the "adjustments hypersensitive...". I recall that the zone of adjustment acceptability was much narrower than we are used to with traditional wood parts.<br>

</div></div></blockquote><div>Likewise. It was my understanding that a lighter gage wire was being considered. In my experiments with the rep lever half of the spring ----- I shortened this segment and re-curled the top with rounding pliers keeping the curl well within the rep slot. This shortened segment had to now work harder to lift the hammer yet left a reasonable amount of tension in the jack segment. BTW, my parts were all hard bushed.<br>
