Dear Scott Isaacs: I f you are having problem with Herringbone
chains , We do over 100 repairs a day and you can bet your life a
Herringbone is one of them. The trick I use is to use white out. We go
back about 1/16th from the break and coat it with white-out, so that
the solder cannot flow up the chain.Then flood the 1/16th with with
solder then pickle . Trim each end thin so they will lay across each
other recoat with white-out and solder while pinned down on a solder
block ,. The pins will also draw away some of the heat to stop the
solder flow up the chain . The solder will only cover about 3/23 and
the chain just needs to be trimmed with disc. If you have any
questions email me I I will Fax a diagram , about this or any
repairs. John Gardner. @John_Gardner
