Paul, Quoting "Paul Chick (Earthlink)" <tune4@earthlink.net>: > Can you post a picture of your picture of "the correct jack > alignment..." Actually, the picture Barbara provided is pretty close...if you bring the jack sufficiently far "forward" (toward the keys) so that the back edge of the jack lines up with the perpendicular part of the shank (inside the knuckle), the jack will probably escape too soon for much control and/or power. If you align it such that the front edge of the jack aligns with the same point, it appears (from this picture) that the back edge of the jack will be pretty close to the back edge of the yoke/window in the repetition lever...and the action will fell pretty "clunky". While I do hope Joe is able to push out the "correct" specifications, with an action of this age and condition, having something which works reliably and predictably is going to be of more value than precise attention to published details. In Thayer actions, the knuckles wear differently than they do in other designs; and they (the knuckles) do not respond as well to traditional "reshaping" techniques. The picture demonstrates this pretty well. Also, check the spacing shim located between the whippen rail and the action bracket; and, while doing that, check the alignment between the drop screw and the "bumper" felt on the top of the repetition lever. I suspect that someone, presumably at the factory, from the looks of things, had to think about spread issues to get the alignment of the jack and knuckle to be as good as it appears here. Best.
