[CAUT] bridge cap sanding

[Jeff Farris]

Hey list,

Here at UT Austin, when restringing a piano, we replace agraffes and 
replace bridge pins. Standard bridge procedure includes, scraping off 
the old DAG, sanding the caps, gluesizing the pin holes, re-notching 
the bridge, etc. Here's my question/comment. When sanding, the old 
string groove is not completely removed, but it is minimized 
significantly. When I'm not trying to alter downbearing, just 
reproducing what was there (mostly), is that OK? In other words, is 
leaving a little groove a problem? Is removing it completely more of 
a problem or more desirable? Y'all have fun with this one.

Thanks,
