The Norris adjuster is a subject of much debate, but one thing that is pretty well accepted is that a single thread version is less fragile and/or prone to thread wear. My question on them, is how is the threaded rod captured in the piece that has the pivot pin for lateral adjustment? In the double threaded version, the left handed thread is permanently attached to it, but in the single thread version, I imagine that the end of the threaded rod has to be turned down and captured using a retaining clip or something. Anyone here know for sure?

I haven’t been blessed with a Norris, and in the old-tool hell that is southern AZ I probably never will. But there was a decent article on the adjusters here:
There’s a closeup that might shed some light on the subject.

I’ll echo what Joe wrote. No Norris here, but I did a lot of research when I started building infills. A internet search will find drawings. If you’re trying to make one, there are lots of ways to catch it. It’s been done by a lot of manufactures from Shelton to modern Stanleys.
