We've had a number of re-galvos over the years, and the quality of the jobs have varied quite a lot, both in thickness of retained coating and smoothness of the coating. If it is lumpy (as it has been a couple of t imes) it sticks in the gypsy
and jams the windlass
until it finally wears down the bumps... a BIG PITA.
It seems that a lot of galvanizerias have been shutting down of late, likely due to environmental issues. They can be pretty horrible in OSHA terms, too... I remember one in Oakland CA years ago that was right out of Dickens! A really scary place to visit when delivering and collecting our chain! Anyway, it is getting harder to find ones that do chain, so posting
addresses or links here on CF would be useful.
Yeah.. how did they do it in the first place? It surprises me that galvanizing temps would change the heat treatment...?
