Bridge Tops & Epoxy

[Isaac OLEG]

Hello,

Well , when you are there (new bridge pins) , you can work clean the
termination point on the bridge (chiseling with a convex 2 sides
chisel).

Not doing many of these repairs, I've done it twice, and the 2
instruments where hardly having any weak string/false beat.

What I am not sure of is at what moment may I lacquer the notches,
graphite the top ,after cleaning of the extra epoxy if any (BTW, it
cleans very well with a wet rag a brush and acetone ). The lacquer I
guess may be applied last, but I wish not to put some on the new pins.
