Norseman Compression Fitting Wire Compatibility

I have a 6mm Norseman turnbuckle stud on my forestay. I'm replacing the standing rigging and I would like to re-use the fitting if possible. I have spare Tylaska cones for the Norseman.

Is a 6mm Norseman compatible with 1/4" 316 wire?

I'm not sure. There's enough variability in the caliper measurement depending on whether I'm on a strand or off of it that I cannot tell.

And 0.250" is pretty darned close to 0.236" (6 mm).

It should be fine.  Wire diameters do stray from the nominal, so the Norseman system was quite good in accommodating this if applied well.  Norseman was standard fitting on all S&S Swans in the 60s till early 80s. 

The important thing I remember was to have the core strands a pretty snug fit inside the cone.  If that was OK, winding on the outside cover would do the deal.

But if in doubt ask Tylaska.

Hmm... ask Tylaska. Yeah, I'm a dork, shoulda started there.

For posterity, here's Tylaska's page for that

It turns out that there are different cones (and I assume different bodies as well) for the metric vs imperial hardware.
