Thanks one and all for the suggestions. As it turned out, I got to thinking and looking and pondering and ended up just filing the front (hammer end) of flange profile back enough so that I could get the centerpins lined up with the old center pin line. This was a bit time consuming, but it got done in about 3 hours. It required a bit extra in terms of shank traveling and making sure the centerpin heights were even... but not so much extra in the end. This brought back the knuckles so that they were just 1.5 behind the old ones, and that turned out to work really well with the jacks. The jacks were too far back relative to the knuckles to begin with, as I said in my first post. I wont know until I start regulating just how off 90 degrees the jack will be from the knuckle... but it looked pretty good on the bench. I wanted to go with a 17mm knuckles to center to accommodate a number 6 SW curve... just under mid medium. Thats about as light a hammer as I could ask for these days. The old set weighed in at 3/4 lows.... really light. Samples were amazingly enough dead on the Stanwood curve. I will be maintaining the same BW, and keep the existing whippen assist springs at their same basic tensions. Customer just doesnt have enough money for new whippens. I'll take some pics as I get further along. The keys and whippens are dated 1879. The instrument is in really quite good condition for being so old. ' Thanks again one an all for the many good points and thoughts. RicB
