     Also for example with Stwys and others but Stwys are what I check =
most often the string heights can vary by 2 or three m.m in the tenor =
treble yet Steinway and others will send you a standard bore hammer of 2 =
1/8"bass bore and 113/ 16".  However the tenor sections can be 2 to 3 mm =
higher in the mid tenor than in the treble and can also be sloped one =
way or another.  The bass as well can have similar problems.  Some older =
Stwy B's and D's had bore lengths of 2&3/8" bass and close  to 2 " tenor =
treble so if standard bore hammeres were used in this application =
regulation,geometry and touchweight problems would be a big deal to your =
client and your reputation.=20

I agree.

During the 70s we received a set of hammers from Steinway for a new B =
that needed new hammers. The bore was so far off they wouldn't possibly =
fit the action. On calling the factory I was told to plug them and =
redrill. Sounded a bit odd, but I was assured that is what they would do =
so I tried it and it did work out quite well. I have now done this on =
several other occasions over the years with hammers, both from Steinway =
and from others, sent pre-bored but not appropriate to the piano at hand =
with good results.=20

But, why bother? You're best off drilling them yourself to measurements =
you take yourself from the piano in your own shop. In the long run =
you'll have fewer problems. It's a relatively easy process and it really =
doesn't take that long. Either to learn how or to do the job.=20
