What did the = person you studied under call it? =3D=3D=3Dric Ric, Thank you!!!!!<G> What my mentor called it was: Hammer Shaping! I've since convinced him = to call it Surfacing, Resurfacing or Filing.=20 I find this to be a constant irritant. The oldetimers called it = "shaping" and everyone else just follows along like sheep! Sheesh! The = term invokes an incorrect approach to the process, thus making one have = the propensity to do the process incorrectly. It's a mind image thingee. Once one grasps the concepts of what actually SHAPES A HAMMER or put in = proper context what actually DETERMINES the shape of a hammer, then it = will all be clearer and cause one to approach the process correctly. THE SHAPE is dictated by several factors: 1. the shape of the moulding. = 2. the shape of the under felt. 3. the shape that the hammer felt is = skived to, pre pressing. The secondary factorsw are: 1: the shape of the = caul that the hammers are pressed into. 2. the amount of pressure during = pressing 3. how long the hammers are left in the caul. All of these = things dictate the SHAPE of a hammer! In actuality, we really are "peeling", (a LAYER off of), the hammer. If = we follow the "natural" curvature, (ie shape), we will have taken off = continuous layer of felt. This leaves a continuous layer on the top = surface of the hammer. IMO, this lends to better/easier voicing = possibilities. Thus making our work easier.<G> If there is not a = continuous layer of felt on the top surface of the hammer, OR if the = hammers have been worn/surfaced too many times we are contending with = short layers that are holding very little pressure in an uneven manner. = Sound familiar? On that, I'll let y'all ponder, for a while. For those who choose to = continue to use the archaic/incorrect term, so be it. IMO, ya just don't = get it!<G> Most on this list espouses making changes for the better, in = our industry. This is one of those changes, that is way overdue. Think = about it.
