[CAUT] Baldwin Accujust

[Delwin D Fandrich]

Sure. My pinblock design for the grands did not pass the "boil test."
Fortunately this test did not apply to the verticals so at least the 743-5
design (the "Hamilton") got a decent pinblock. This block used thicker maple
veneers through about the back 2/3 or so and thinner veneers through the front
1/3. Nice block--strung well and tuned nicely. I don't know what the other
verticals are using.

   "I've always assumed... that makes the Baldwin so difficult to tune"

Part of that is the tightest pin block in the industry. I know a guy who was a
piano tech at a school in PA. Dad. He showed me once when visiting the enlarged
tuning pin on an SD he installed after breaking off a pin that wouldn't turn. He
drilled it out. Sometimes the Baldwin Concert Grand will start rolling across
the stage before the pin will start turning, if it ever does. 
  Some attribute the stability of the Baldwin to the downbearing. I think it has
something to do with the pin block as well. A pain to get in tune, but it stays
there if you do it right.

I've always assumed all that nasty metallic sounding noise that makes the 
Baldwin so difficult to tune and produce a musical tone was the result of 
the vertical hitch pin.
