This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hello David The felt used is long, tapered and triangular in cross-section with a very long base line - rather like the section through a Swiss house roof. The length of this base line tapers smaller to the treble end. The apex is put against the tip of the hammer cores and the glued felt folded round those cores - maybe twenty at a time - and then pushed into the, presumably pre-heated caul and left to cool dry. I assume they use hot hide glue. When dry they are removed from the cauls and stapled. From this process you can imagine the tension in the felt at the striking point! There is a set of cauls with the requisite tapering according to the size of hammer graduations. That's all I know about it!

Maybe someone could explain how they do that. The only thing I can figure is they remove all felt from moldings, glue them together to make up a large molding like new hammers and then glue on another hammer felt block...cutting apart at the old seams?
