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. |

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! |

While I have certainly suffered my share of soldering iron burns, I don't recall grabbing one by the wrong end- probably due to always using a stand or holder, at least since the days of replacing my Remploy iron which I was given when I was about 11. If you don't know the Remploy, it had a triangular section on the handle which kept the hot end clear of the bench. I regret no longer having the Remploy. The ex-BT iron came with an insulated clip on pot-like holder. I was told these were designed to clip to the old telephone exchange racks. |

... Brian, a largely unhelpful tirade from you in which the only relevant bit, and not in itself helpful is your comment, "solder, with a decent sized iron". However, as must be apparent to all your readership, your reply, as always, is a thinly disguised vehicle to make several personal remarks. Why do you continue to behave as does a 5-year-old on a daily basis? Shame on you. Ralph Mowery wrote: wrote in message ...

It sure beats the gingerly use of a junior hacksaw! I'm with him on the method, tin the shield, pipe cutter is good, but I use en exacto or utility knife, guess my pipe cutters are to old and dull. It's even worth it to tin the holes on the PL-259 and let it cool before you start. Oh, and don't forget to install the sleeve first!! Mikek |
