Then you will have a real feel of what it gives. Such high weight figures could be the ones of a compressed action with high ratio, but if you are in a good configuration you could use these leads and have a good touch I believe. Beside, 40. 42 .44 g seems very light to me. more in the 48 - 52 range. Done a fast leading with evening of SW and check of all BW yesterday , took 12 hrs work including evening of SW, and re leading. I could use 2 or 3 hours more to nitpick some little defects but the action is really even ( Steinway D) with this 2/3 Stanwoodized job, and I liked the friction tracing all along. The jig from Stanwood is a must for un leading keys Regards.

You might be lucky here and be able to get away with a quick move of the capstans in a couple of mils. If you are regulating well at a shallow dip then thats a good indicator that you have some room to move here. Otherwise... it would be helpfull to have a few othere parameters like Strike Weights, knuckle placement and radius, Front Weights and the like. Cheers RicB "David M. Porritt" wrote: I have a Baldwin SF-10 here on which I just measured the action weight. C4 is 60 grams down, 45 grams up! Friction -- obviously is good -- down weight bad. I hate adding lots of lead to the keys, but on this piano there are only 3 weights in the bass section, 2 at C4, only 1 in the upper treble, and actually 2 in the _back_ of C8. It appears that they did straight pattern leading on this one. I can add 1 - 2 weights to each key and bring it down to 44 at A0, 42 at C4 and 40 at B7 (I'd probably just take out a back weight on C8). There is a point of diminishing returns on some actions where you can reduce downweight by adding leads but the additional inertia makes it feel to the player as though it is as heavy as it was before. Does anyone think I'd get into inertia problems adding this amount of lead? dave _____________________________ David M.
