How to Solder a Spliced Joint
How to Solder a Spliced Joint to NASA Specifications This material comes from NASA-STD 8739.4, which is a great reference if you’re interested in best practices for interconnecting cables and wires. This splice is known as the “Western Union splice”, or the “Lineman’s splice” and is the preferred method for twisting solid-core wire leads together for inline electrical connections. Developed during the heyday 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... Read more...
