The worlds first NZ120 blog. A mix of history of the scale, latest news and some modeling thrown in on the side. Poor spelling an added extra.
Some commenters on Friday’s post about using a washer as a soldering aid noticed my sloppy splicing technique and were kind enough to educate me about the so-called “Western Union splice,” aka the “Lineman’s splice,” which is the preferred method for twisting solid-core wire leads together for inline electrical connections.
Developed during the heydey of the telegraph, the Lineman’s splice is designed for connections that will be under tension. It is commonly claimed that, properly made, a Lineman’s splice is stronger than the wires of which it is composed. In any case, it is a time-proven method, and, coolest of all, one of NASA’s Required Workmanship Standards. To wit, in a NASA-approved Lineman’s splice:
Though the Lineman’s splice was originally used without solder, today soldering is common. And NASA insists on it:
This material comes from page 84 of NASA-STD 8739.4, which is a great reference if you’re interested in best practices for interconnecting cables and wires. [Thanks, Alex Barclay!]
