StaLok and Norseman blues

[Robbie.g]

Although i have not had problems with the cone slipping, may be the cone and wire don't match (imp cone/metric wire??), or the wire is indeed the 'cheap stuff' and there could be a tolerance issue there ..
There are a couple of the things i do that you may find of use. these are mostly to avoid picking up a strand, which is a fairly common problem.
After the cone is inserted and the wires reformed around the cone bring the top part of the fitting down to hold the wires in place, equally spaced etc. then file the outermost sharp edges off the wire, this combined with a small amount of lube in the former part of the fitting helps heaps.

Cheers
