Larry Mayo wondered how to remove epoxied bridge pins. Some epoxy
requires mold release on the pins. Others do not. The trick is always
the same: Drill some oversized holes in a block of wood. Get some pins,
stuff the holes with epoxy. Stick the pins down in the holes. Allow to
dry. Twist and pull out the pin. This method never fails, Larry. Try it
first. Chances are, if you start with the original pins, they will have
just the right amount of dirt and oxide collected to act as mold
release anyway. Then you can pull those old ones out of just about
anything, redrill for new half-size up pins, and plant the new pins
when you've finished. No sweat.
