Partial Set Tenor (Middle) Upright Piano Hammers, Fits Baldwin Hamilton & More

Description

Quick note:  I've been getting some questions along the lines of "will this fit my piano".  I certainly don't mind questions and will be glad to help with some additional information.  I've added a photo showing and hopefully visually defining some of the measurements and angles involved.  Bore distance and rake angle are probably the most important as they determine the strike point of the hammer.  Please read on and feel free to ask any questions you have, providing the bore distance and rake angle with any inquiries when possible.
First photo shows the hammers with the largest, middle and smallest hammers in this partial set. 3 subsequent photos show the thickness of the felt. Don’t worry if your set doesn’t match up exactly, in all the years I’ve been rebuilding it is rare to get a set of replacements that are exact and this particular measurement isn’t critical like some dimensions are. Last photo shows some of the terms used to describe various measurements.
Partial set of upright/vertical piano hammers. Perfect fit for most of the Baldwin Hamilton studios (at least 1970’s on); however, these will fit many other pianos as well, but not all - so please measure to be sure and feel free to ask questions as needed.  Hanging hammers is not impossible but is one of the more challenging aspects to piano servicing and rebuilding.  Dimensions and critical measurements are as follows:
Hammer width - tenor (middle section) - 10.3mm (0.408")
Bore distance (tip of felt to center of hole for shank) - tenor: 63.5mm (just under 2 1/2")
Bore angle* - tenor (middle section): varies from 12 degrees in the low part of the tenor section gradually to 2 degrees in the upper part of the tenor section
Rake angle* - 4 degrees
Quantity in each section -  tenor: 30 (numbered 29 through 58).  If you have a piano with more notes in a particular section let me know and I'll see what we can do.
*Note about bore and rake angle.  These hammers have a shank hole bored to about 0.234" which is somewhat oversize for the 7/32" diameter shanks (0.218").  This is intentional and done to provide "wiggle room" when gluing the hammers to the shanks and allows you to "dial in" the angle best suited for your application.
If these dimensions are off from what you need and you want the challenge of boring your own hammers... you can use some of the included shanks to plug the existing holes and then redrill…. if you're a beginner this is not for the faint of heart but at some point in the past all of us who do this started with our first set of hammers.  You will definitely need a drill press and a fixture that allows you to precisely set the required dimensions but this is do-able.  I'm willing to send pictures of the fixtures we use if that helps.  If you mess up one or two (or a few...) I have broken sets and spares on hand and don't mind sending a few (free of charge, including domestic shipping) if you've bought the set from me.
