<DIV><FONT face=Arial size=2>Gee willikers, you're the only one =
curious? It's a
handy little way I devised to very accurately mark the inner rim with =
new rib
locations for notching. Rather than marking and notching the rim =
directly
from a design pattern and then trying to get the ribs mounted on the =
soundboard
exactly correct so they line up with new notches, I build the soundboard =
from
the design pattern first, and then notch the rim based on the rib =
locations on
the completed soundboard.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This process was developed in part to =
solve the
rib/notch alignment problem posed with building and installing a =
"Belly in
a Box" package where the soundboard is built in my shop, but is =
installed in a
different shop.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>NOT that my soundboards EVER vary even =
a zillionth
of a millimeter from design specifications, but....... (Hey, I'm talkin' =
real
life here!)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>First I tape off the rib ends so the =
PlayDough
doesn't stick to the ribs.</FONT></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then I goober on a little wad of =
PlayDough about
where each of the new rib ends will go and press the soundboard into =
place. The
rib ends will imprint their exact locations into the Play Dough
wads.</FONT></DIV>
