<HTML>Grand or vertical?  It wasn't entirely clear.  In any event, there are ways around this problem.  If it is a grand, just think, first of all, what you have to do to level keys in a grand.  You can't pull them out, place a punching, put it back in, then see if it's right or at least better, the way you can in a vertical.  You have to *estimate* the punchings needed, then take the stack off put them in, put the stack back on, then see what the results are, then repeat this process until you are satisfied. So, Patrick Draine's idea was excellent.  If you are going to need to turn each capstan by a large amount, say, a full turn, the best thing to do is to just take the stack off and do that, then see where you are from there.   The suggestion of an offset tool is a possibility but whether or not, try this:  When you have the key fully depressed, can you reach the capstan?  If you can and you have got a good rough hammer line job done, when you see a hammer that needs to be raised or lowered, press the key down, (or often, a gang of them down each time so you don't have interference from neighboring parts), then reach for the capstan and give it a crank in the direction needed.  It can take a few tries to get it right as opposed to adjusting it when at rest but it can be done.  This is where knowing how much a crank of the capstan screw will change the position is important:  knowing how to make a good *estimate*. You can use the depressed key technique in any case where depressing the key makes the capstan more accessible.  In verticals, I take the key out, make the rough adjustment, then sometimes make the fine adjustments with the depressed key technique.
