Just remember that solder does not survive contact with soil for very long. AM towers are connected to their radial fields in a similar manner. The ground ring is typically buried. But connections ar

I detest the prep and the inability of any Weller soldering gun I own to heat the barrel of the connector up to soldering temperature in my lifetime without melting the cable jacket. I've migrated to

I'm no structural engineer, so perhaps someone else can bluntly point out what a stupid idea this is. What about filling the pipe with foam, the kind used in boat building? It's light and pretty stro

Braising is a way of slow cooking meat! I'll bet that translated into French wonderfully! Brazing is a method for joining metals. Technically, it's more like soldering than welding, as the base metal
