Tom Sheehan rote, 11/27:
<< I'm encountering a problem with positioning the sostenuto rod properly to
prevent the tabs from hopping up on to the rod when it's engaged. >>

Assuming the rest of the regulation is right (rail height and inclination at
rest), what allows a the tab of an underlever not already held up be the
engaged sosty rail to hop up on top of the rail, is the fact that the rail is
set far enough out that it is only holding up tabs by a finger nail. Set the
rail so that it's holding tabs by the specified 1/16", so that a tab flying
up at it from underneath will have to force its 1/16" by the rail to get from
bottom to top side.
