Technical Tip (15) Bathe your nipples for a stronger joint!

When soldering a cable nipple, the best way to be sure solder has fully penetrated the joint is to immerse it in solder rather than using a soldering iron, and this pipe fitting from a builders’ merchant makes an ideal little solder bath.
Buy a stop-end fitting intended for copper pipe and with a gas torch, melt a stick of plumber’s solder to fill it to the brim.  With its flat base, the little pot is perfectly stable when you to need to dip the cable in. After the job is done, allow the solder to cool and the bath can be kept in the workshop ready for use next time.
