<div>Here is a clear picture of the shank and flange currently
supplied by Renner for the _New_York_action. The distance from
centre to middle of roller core is advertised as 16.2mm. (Abel does
16mm.). The standard measurement, and that used for the Hamburg
shanks, is 17mm.</div>

<div>Compare this with Greg's picture and you will notice not only a
difference in the wood used for the core but an apparently quite
marked difference in the position of the drop screw even allowing for
parallax. The quality of the buckskin is also different.</div>

<div>And here is the new Renner shank and flange lined up with the
original NY Steinway S part. There is almost 2mm difference in
the disrance from the roller core to the flange profile. In
other words everything is moved inboard nearly 2 mm. What do
do? The simplest solution is probably to pack the lever rail
with card along the top of the screws and pack the near edge of the
hammer rail to force the flanges back as far as possible -- note that
the profile has a wider central section than the original, so some
adjustment is possible without cutting away the far side of the
flange. One way or another it is possible to reduce the error to
manageable proportions, and I've seen some pretty extreme fixes of the
kind on Steinway's own work. Nevertheless Renner need to be told
that their dimensions are wrong. And a fat lot of difference
that is likely to make!</div>
