Greetings, I wrote: >block the whippen so that it cannot move, and regulate the balancier so that the jack can just be felt moving across the leather. I find that I can do this and not see any dropping of the hammer, which suggests that there is no lost motion between the two. < Dave replies: << If your blocked wippen did show some hammer movement when the jack was tripped out that would indicate that the jack was indeed holding the knuckle with no lost motion and the hammer dropped down to the repetition lever when the jack moved away.<< I don't need the jack to hold the hammer up, just provide a positive stop to the hammershank at rest. I want the least amount of contact possible without there being any lost motion, and feeling the jack touching the leather is the way I have found to get there consistantly in the least amount of time. I realize this is a fine point, but its practical aspects are what make it valuable to me. I can set 88 balanciers by feeling for the slightest c ontact between jacks and knuckles faster than any other way. If I were to set them by feeling the tops of the mortices, I would still have to double check them to make sure that all jacks would return.
