Even better than the reamer is a 1/8in round file, applied sideways across the top of the hole to create a thin feather-edge of bare brass which is much easier to solder. If you then use a hot air gun to pre-heat the connector body to about 100degC, even a 40W Weller iron will give a good solder joint. Best of all is to avoid that design of connector completely, and change to modern designs that don't require heavy soldering. Even if you're not prepared to invest in crimp tools, you can still buy the pressure-sleeve type which has vastly improved cable retention. 73 from Ian GM3SEK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
