half-punching

[Barbara Richmond]

Hi Stéphane,

I was only considering gluing to the bottom of they key in this case of using a half punching with the Steinway half round balance rail bearings.  I don't think the bearing would tilt if the half punching was under the bearing, would it?

  Hello Barbara.

  I started also using half punchings, after reading about in the list.  I'm enchanted.  It makes the front weight measuring so much easier, as the key moves clearly from rest position to let off position in one movement.  I measured that a whole punching set up needs as much as 6 grams more in the last portion of the travel to get clearly to the let off position.
  May I ask, why would you glue a card half punching on the bottom of the key ?  I recall having read something about that, but I would myself and I think avoiding using glue (hard thing) in such a critical place (fulcrum), being afraid of harsh sound or even clicking.

  Greetings.

  Stéphane Collin.

    Hi all,

    Back to using half-punchings.

    Has anyone ever tried gluing a thinnest card half punching on the bottom of a Steinway key that already uses the half round balance rail bearings?  Results?

    Thanks,
