Recrowning

[Richard Moody]

In reply, so as to keep the thread on Horace's comments, I seem to
remember Leonard Jared talking about placing a wedge in the bridge
ala keystone fashion. This would involve cutting the bridge in such a
way to insert this as I don't think he mentioned removing the bridge.
 This is so vague in my memory, I am not sure of any other details.
Perhaps some one else has heard of this.  The soundboard had to
"jacked up" the incision made (before or after?) in a predetermined
spot, the wedge inserted, and the sb let back down.  This was only
from "hearsay" and  was it from him even??
	Even if this is a case of me not distingushing dreams from reality,
(is that why I perceive some saying, "Ah ha, he has let the cat out
of the bag?") on THINKing about this, more than one wedge might be
needed.  But where?  Also I would like to ask, how does the bridge
run in relation to the crown?

Ever seen a wine cork placed between the wooden post and a rib?
Probably to stop a buzz. Not the one created by uncorking the wine
bottle.   rm
