The angle of the butt leather is also more "open" with = the hammer forward, making it even easier. However, often with slow key = release, the jack often drags on the back of the butt, and the hammer = returns to rest position before the jack gets back under. In this case, = with the hammer fully back, one wants only enough lost motion to let the = top of the jack slip along the leather (and, I might add, the little = stop felt should allow it under only so far as necessary to fully engage = the butt upon the next keystroke. I hope that's what you meant by your question. If not, I'll try again. Bob D=20 Thanks, Bob. I was working on a couple of uprights and followed your = description of the jack to hammer butt angle. Works out very nicely, = and quicker than my "try this and see" method. Paul C ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
