[CAUT] Hammer shank cutting block

[Paul T Williams]

Sorry Ted, but no photos were attached!

I've also found a Dremmel tool with a cutter works nice and neat as well 
with little sanding....and very fast!  I just tried this with my first set 
of WNG carbon fiber shanks, and with a few minutes of careful prep (ie 
covering the hammers to keep the black dust off) works very well. I'll use 
this method again even with wood shanks.  Even a first try took about 15 
minutes, and I'm sure it will speed up next time. 

Are you still in Banff, Alberta? I still have that hammer-top "squaring 
off" sanding jig you gave me some 15 years ago and use it often!  (new 
sandpaper replaced, of course! ;>)  )  Thank you so much!

Best,

Paul

[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.
