What's the solution to soldering through to the underlying braid in a PL259
if the only soldering iron small enough to engage the holes is a low-power jobbie? Perchance the solution lies in using a junior hacksaw to make a slot between two of the holes so the big iron can get in there? This is for an outdoors connection, so I want to ensure that it is sound. |

This is for an outdoors connection, so I want to ensure that it is sound. I use a Weller pencil iron. I tin the braid on the coax before inserting it into the fitting. You can use the big iron to tin the areas around those little holes before you do anything. It doesn't hurt to sand the area around them first. When the braid is tinned, and the fitting is tinned, it doesn't take much of an iron to get the solder flowing through the little hole and onto the braid. Irv VE6BP |

Buy or borrow tools appropriate to the task. That is the way to do it. Get a big soldering iron that will really put the heat to it. I have used a Weller soldering gun in the past, but now use a 100 watt iron. I bought a used one at a hamfest. I think you can get some at the Hobby Lobby store if in the US. They sell them to people that make things out of leaded glass sort of like the old church windows. Switch to the silver type connectors as they solder beter. If still using the plated brass ones, take a file and cut the plating back to the brass where you want to solder. Putting a little liquid flux on sometimes helps, especially if the braid is all copper and not tinned. I just about quit soldering connectors. Bought a crimp tool and crimping them on now. You can get a crimping tool for around $ 20 and the connectors are aboout the same or less in cost. |

They sell them to people that make things out of leaded glass sort of like the old church windows. An old Solon, ex BT, iron is ideal, I think they are about 50W but the key thing is they have a decent sized bit. That means a good thermal mass to get the plug up to temp. quickly. In the UK, fitting a Coax plug is part of the Intermediate licence and I teach the following method, especially for RG213 etc. Strip the PVC jacket. Using the plug as a guide, decide which area of the braid will be under the holes. Tin the braid, using a bit of liquid flux. The tinning must be very light. Using a pipe cutter and the plug as a guide, cut the surplus braid away. The tinning ensures a neat cut with no stray 'whiskers'. Next, trim away the inner insulation, about 2mm beyond the tinned braid. You should now be able to assemble the plug and see the inner emerge from the centre pin and the tinned braid through the holes. A small amount of liquid flux around the holes and solder, with a decent sized iron, and you will get a good connection. Solder the inner. I've taught countless Intermediates this technique, including my daughters when they were about 10 or so. After all, fitting a 259 is a basic skill. Anyone who claims to be a home brewer should surely be able to do it. As for having a soldering iron large enough, it is the kind of thing I would expect an active model engineer to have- if someone needed to borrow one. |

Mine was 65W, IIRC. Haven't seen it for a while; I think it's out in the garage. And yes, they are polarised. I can remember holding and staring at something I was about to solder and reaching out for the iron without looking. Picked it up by the wrong end. You only do that once! |
