This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Bob, Yes, the weights are SW, and not head weight. Although my hammers are a = bit heavy, they're not really *that* heavy. For the most part, they're = in the 3/4 medium to top medium range. I do like a heavier hammer, as = it seems to give me more dynamic control. If I had the strength to = handle them, I'd probably want even heavier hammers still -- perhaps no = higher than Stanwood 10s. In contrast, I can't stand playing pianos = that have light hammers. Heavy works -- at least for me. These hammers = are only slightly heavier than the hammers I already have. As truly, = truly horrible as my old hammers are, I do like the "feel" of their = weight. Everything else in the action seems fine, and I won't be doing = any reconfigurations (e.g. moving the capstans). Oh, yes, the new = shanks do have just a tad (.5 mm) longer a knuckle placement (18, vs. = 17.5 mm), so that will decrease the new SWR ever-so-slightly, = compensating somewhat for the ever-so-slightly higher SW. I've already had these hammers hung and shaped. The job was done quite = expertly! Of course I can tweak the weight here and there with the = removal of a bit of extra molding. I don't want to touch the checking = surfaces, though, as they're very nicely shaped. I'll probably remove a = bit from the sides of the tails, and perhaps just a shade from the cove = side. For those hammers that need a pinch more weight, I'll probably = use a bit of lead, per some of the suggestions I've received. But since this will all be put off until after I see how the hammers = feel and sound, it's all quite a bit of arm waving right now. If the = hammers are really too heavy, which I highly doubt, I can always even = their weights out towards the lower end of the jags in the SW curve. = I'll know more, once my keyframe returns home from its little trip to = the spa, and I can put some of these pretty hammers into motion! ;-) Peace, Sarah ----- Original Message -----=20 From: BobDavis88@aol.com=20 To: pianotech@ptg.org=20 Sent: Sunday, August 22, 2004 11:56 PM Subject: Re: SW heresy? Hello Sarah, I was looking over your graph. This is strike weight, right? Not head = weight? Even so, it looks like it might be unnecessarily porky for a = Steinway clone. What kind of hammers are they, and have the sides been = tapered? Head to tail, or just tails? Has any additional coving been = done? As others have mentioned, doing your own tapering with a table saw jig = like the Spurlock goes a long way toward evening up (and reducing) = weight. If they are 11 mm wide, they may not need to be, which you can = check against the string spacing. If they do need to be as wide as = whatever they are, you can just start the taper at that width.=20 After tapering, I weigh each head before coving, and can make a 0.1 - = 0.2 gram evening-out adjustment in the weight by varying the cove, = without having it show.=20 I think you are wise to put off final adjustments until you can put = some hammers in the piano and see what kind of weight the action wants, = as well as what kind of sound you're getting.
