Gang, I received this reply from John Dewey Gerry Cousins BEGIN REPLY: I do not know the date when Steinway changed from the cast holes to the machined (broached??) holes. I did a Steinway “L” serial number 428551 which had the large cast holes. I am at my sisters and do not have anything to look up the manufacturing date by serial number with me. I think this piano was from the “ CBS era “. In 2000 I ordered new action brackets from Steinway and they had the machined small holes. I have rebuilt Steinway action frames from as old as 1877 through the end of the “CBS era“ and they have all had the cast holes. So far I believe I have only rebuilt 1 frame with the machined holes and I do not remember what the serial number was. Sorry I could not be more help.

I'd have to go see some pianos to confirm, which I'm not allowed to do for a few weeks yet. But I'm pretty sure it was in the early '90's, not late '80's. And this one was likely a decision that, once implemented, went into the action department from one order of brackets to the next, rather that working its way through the various models. Of course, there's quite a time spread from the soldering of rails to when the finished product shows up in for serial numbers, so there is probably a 2-3 year spread in which both versions may occur. > > Doug > > On Thu, 1 Jul 2010, Horace Greeley wrote: > > > > > Hi, > > > > In addition to checking with John Dewey, while I am not sure when the transition was started, it was completed by 1995. > > > > Based on observing the process of some other changes, I suspect that this changeover was started several years earlier, as other manufacturing changes were also being introduced and then phased > > in...perhaps by model. > > > > FWIW, although the raw stacks produced with this later method are more consistent, I am not sure that the angles between the rails have been maintained.
