Checking My Nuts

[Dr Stan]

I was taught, back in the stone age, one could engage even threads on any line, numbered or unnumbered. However, this was using threading dials that were numbered one through four (90 degrees apart) with unnumbered lines half way in between each numbered line.

Odd numbered threads, either on numbered or unnumbered. Start with a numbered line, continue until finished with a numbered line. Or start with an unnumbered line and continue with an unnumbered line.

Fractional threads, pick a line and stay with it. Typically I'll only use the number one line.
