Bridge over troubled waters

[Isaac OLEG]

Hello,

The more shiny bridge pins I see look like stainless to me, I would be
surprized of plated pins, can't the plating tear down with the wire
friction ?

Are brass pin wearing faster than steel ones ? stainless is also a
somewhat soft metal in fact.

Have someone any idea on the difference in tone due to different
material used ?

Best Regards.

Isaac OLEG

Likewise.

This can be a problem. We've made our own pins to the required size
by getting silver steel centreless ground to the oversize diameter we
require, then cutting the pins from the ground lengths of silver
steel. But its a slow and costly process. Renner supplies bridge pins
in several graduated diameters, but these pins do not have a very
high standard of finish. We've been using them to date, but I'm
looking for a better quality pin.
