For years I have been repairing stampado style bracelets and
necklaces; bracelets that are hollow forms that have the top side
stamped out by machines, and the other side a flat plate soldered
to meet, creating a large looking form without the heavy weight a
solid piece would create.
Anyway, these forms are connected to each other with pins
through one end and coming out the other. These pins and holes
wear out, and it becomes necessary to replace them.
My usual technique is to find wear the pin is, either by
educated guessing or occaisionally heating gently to find the
solder stain, marking with a sharp graver, and then drilling
using first a fine drill in my flex shaft to drill through the
pin. I than graduate up in drill sizes until the hole is clear,
and replace the pin.
My problem is this: I find that if I am 'off' a tiny bit,
sometimes the drill bit breaks, creating the difficulty of
removing the old bit ( if it hasn't dropped through). The other
problem is that it takes me too long to do. There must be a
quicker way than my method. \Any ideas??
