Steinway "pinning" dilemma

[Mark Cramer]

I sure wish action makers would
revert to starting off with 19 centerpins, instead of 20.5 or so.

Ditto Fred,

I've been around the ball-park on this one. Renner and Abel both use the
20.25 pins.

According to Wally Brooks, it is a Euro thing, and they won't change it.

Renner's response was; "						"

For awhile I used Tokiwa parts. They come pinned with 19 or 19.5 I believe.
This provides some latitude for pinning over the lifespan of the knuckles
and hammers, while 20.25 (IMHO) does not.

In the abscence of replacement flanges, I have facilitated re-bushing to a
nominal pin-size as follows:

1.) Inject the birdseye with a methanol/water solution

2.) Shoot compressed air through the birdseye

3.) Let the flanges dry over a warm source overnight (un-pinned)

4.) Choose a nominal-sized centre-pin for best-fit
