yes if I buy non bored heads at the factory, for Bluethner the price is normal. then I have to bore al hammers with 0 degres angle, our boring jigs are not well adapted to that kind of job, as they use the side of the head as a support generally, there the side angle will differ depending of the location of the hammer

I want to scan in the frame and invert the image. I will then use the inverted image and use a 3D milling machine to cut the new pin block. This will avoid having to build up the pin block and the milling machine will mill away the troughs.
This should make the fit more accurate and the work required will be less. The result should also be excellent as scanning and milling are to the micron in required.

I have compared Bluethner mounted with standard hammers, and with the good ones : the tone is really different.

(also they have a very good felt and pressing, voicing is very quickly done, a pleasure to work with (but provide them strings height and flange center height so you receive the good hammers for your instrument)

PS Pinblock is a part of the sound body on first grade grands (due to transmission of vibrations within the case and keybed, the differnce when delignit is used is obvious)

Then, Delignit is a good material also, for instance on a piano where the case is supposed to be inert and the iron plate is more active to colour the tone, the pinblock can be heavy and non resonant, but maple traditional blocks are always better (for pin tightness also I prefer them)


So the hammers from Bluthner is what I will get. How do you go about ordering the hanners? Do Bluthner sell and ship international?

I am now in two minds about either the Deliginit or the Maple-Buldoc pin block.

The original Bluthner one looks to be three laminated sections of wood. A large thick layer, a thinner middle layer and then a medium thickness lower layer. This has lasted about 100 years.

What is the oldest Delignit block you are aware of?

You can order hammers directly from Bluthner.
Or you can send some samples to Abel and they will make them for you. Send them the first and last hammer with shanks from each section in the piano.

Go for the Buldoc pin block.

You have a 3D scanner? Let us know how this works out for you.

I have come across multiple laminated pin blocks in small Canadian made uprights from the sixties, just not the brand name Delignit.

Hi,
The hammers in the piano are not correct. They have not been shaved as per the Bluthner method. The shanks have been sort of drilled at angles
I would then order them from Bluthner as they should have the correct angles and set up.
