FWIW, in a pinch I have used an ordinary butane cig lighter to solder small joints. Not ideal, but possible[if its not too windy], and often there will be one in someone's pocket or car. The term 'field expedient' applies.
Split bolts can also be found in stainless varieties in case the materials being joined might not like touching copper. Not a great selection of sizes though. Not that anyone uses anything but 99.999% pure "oxygen-free" copper. ;) e.g., > https://www.kencove.com/fence/Split+Bolt+Line+Taps_detail_CBTPSS.php 73 de w4kaz _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
