Re: Re: [Harp-L] Embossing Tools

["Tim Moyer" <wmharps@xxxxxxxxxxxxxxxxxxxx>]

The amount that the reed is deformed down into the slot is 
deetermined by how far you run the embossing "tool" up toward the 
rivet end of the reed.  You can restrict the embossing to the 2/3 of 
the reed slot closest to the tip without causing too much permanent 
deformation.  

This deformation is in part a good thing (you want some of it).  It 
helps to push the root of the reed down into the slot, where it will 
reduce the leakage, even without the embossing effect.

Deformation of the reed during embossing is also an opportunity to 
adjust the reed arc or curvature, which helps set the tips higher 
without bringing the reed up too far out of the slot.

There are other ways to emboss the slot closer to the rivet end of 
the reed.  One is to use something like a glass cutter to "score" 
the slots outside the reed area.  In this technique the reed isn't 
touched at all.  Another would be to support the reed and actually 
emboss the *reed* to widen it at the edges, rather than to narrow 
the slot.

Emboss first then set up your harp.
