[CAUT] Hammer shank cutting block

Hi Ted.

Did you, by any chance, receive the cd I sent you a couple of weeks ago?

I hope so.  If you did receive it, did you have a chance to listen to it?  I
wonder, if you did, what you think of the tone on that recording.

Thank you

Ari Isaac.

Subject: [CAUT] Hammer shank cutting block

The attached photos are of a hammer shank cutting block I made ten years ago
and used ever since for cutting away the protruding stubs of new grand
hammer shanks. It is based on those used in the Kawai factory. Their
technician did a whole set in less than five minutes. I could not work that
fast; it generally takes me ten minutes or more. A Japanese saw (which cuts
on the pull stroke) MUST be used, as a Western saw can result in damage to
the centers. I use a Dozuki (dovetail) saw with a stiff back  9" blade.
Cutting flush carefully makes sanding the shank ends unnecessary, though a
few strokes with a sanding paddle gives a nice appearance. I have the WNG
kit, but have yet to install a set of the shanks, so do not know if the saw
will cut them satisfactorily. If it does, there will be very little dust. If
anyone is interested in further information, let me know and I will post a
sketch and instructions on making the block. It is very simple, and can be
made in half an hour, but one does need a table saw and dado blades.

As for glue - is hide glue unsuitable for the carbon fibre material?
Wherever it makes sense I prefer natural glues. What about fish glue? It
sets slowly ,but has a fast tack, . I find it helps  correct the vertical
angles while gluing the hammers on.
