BNC crimping jaws?
I have a crimping tool for PowerPole connectors, and,
looking at adverts for other crimping tools, it seems that they are all similar with the jaws being removable. With that in mind, what are the dimensions of the crimping holes for jaws that will do BNC connectors? I have the technology (At least a chunk of carbon steel) and could fashion them myself. |

No, I try not to waste my time on the mechanical things. I have 3 or 4 of the crimp type tools. They are almost as inexpensive to buy the whole tool as one tool and several sets of jaws. Keeping up 2 ham repeaters, learning how the Arduino works, putting together uBITX and latest is a boat anchor station takes up lots of time.

The cheapest thing that you can go out and buy is far more expensive than the costliest thing in your junkbox.

I, too, have an Arduino evaluation kit, and a uBitx awaiting assembly should time ever permit :-) |

Rude comments apart, the essence of amateur radio in my book is always doing for yourself the maximum that you can. And that allows for a variable definition. I had to tell you this, but in 1972 when someone needed to put some holesin a chassis for tube sockets, the ham who ran the local code & theory class, an "oldtimer", didn't have the right size punch, so he provided money and we went to the store downtown and got one, the other guy punched his holes and then the "oldtimer" had that size punch. I guess one should be making their own hole punches, even though they don't directly have anything to do with ham radio. Those Greenlee punches were expensive in 1972, at least when you were a kid with limited funds. But boy, I've seen people quote prices in recent years, and what a great deal they were in 1972. We don't roll our own capacitors, though decades ago I did read a magazine article about how to do it, actually rolling paper and foil to make capacitors. It was dated then, since there were better capacitors than those made with paper. But trying something is fine, though I got the idea just from reading it, no need to actually make them. If you insist on "making everything" then you'll never get anywhere, since you'll always be needing to make some lower level part or tool to make a higher level part or tool that you'll never get to putting those hand crafted components into circuits. Yes, building is an important part of amateur radio and there's been too much of a shift away from it, so in the US entry level is 2M FM, when decades ago it would be HF and a home made simple transmitter, usually with some low end junk receiver. But it was at least an entry, something taht no longer happens. Here in Canada, since 1990, the entry level licesne does not allow the use of home made transmitters. so it's really simple to get the license, but then the entry point has to be different from decades ago. That sort of thing is far more damaging to ham radio than whether someone buys a tool or makes it from scratch. Michael |

I happily have a healthy stock. Frank , EI7KS In 1972, QST ran an article on a 80 meter SSB transceiver, solid state, and the case was mostly copper circuit board. But he used some wood to make a frame, which perhaps is more solid for a larger box than just relying on solder to hold it together. But as someone else said, there are lots of boxes out there, even computer power supply boxes, that can be reused with a bit of patching. Slap a piece of circuit board over one side to provide a "front panel", covering up what was before it. Circuit board is certainly easy to drill and cut holes in, easier than aluminum and way easier than steel. Though, the move for consumer electronics is away from metal, so the days of satellite boxes and other things that are metal are often in the post. I know years ago someone here was thinking (or maybe had) built a power amplifier in a metal "IBM compatible" computer case, which has potential, though I haven't seen a really sturdy computer case in some time.

Those Greenlee punches were expensive in 1972, at least when you were a kid with limited funds. But boy, I've seen people quote prices in recent years, and what a great deal they were in 1972. For round holes, using chassis punches is painful. I have a heavy box full of them, and rarely use them. Much better is a Rotex punch: https://www.google.com/search?q=rotex+punch&tbm=isch I have access to several when I need one. Another approach for round holes is an annual cutter or Rotabroach: https://www.google.com/search?tbm=isch&q=annular+cutter These are much better than drills, especially on big holes, because they only remove a "ring" of metal and not convert the entire hold area into chips. The holes are clean, there's very little deburring, they don't wander, and they're fast. When recycling use miniboxes, rack plates, and aluminum boxes, I sometimes have to deal with plugging extra holes. I use a metal plate (or coin) on the inside, and fill the hole with Bondo. I sand it flat before it hardens. Then paint and labels. As long as you don't care about the messy look on the inside, it works nicely. We don't roll our own capacitors, I've made some. Finding high voltage variable caps for magnetic loop antennas isn't easy or cheap. I've only made one so far, so I'm far from an expert on making these tuning caps. There are plenty of magnetic loop antenna construction articles that use home made caps.

But unlike making average bypass capacitors, you gain something from the effort, eitehr saving money, or saving from a lot of scrounging to find them. Michael |

One thing I miss when I retired was access to some tools and a source of scrap aluminum and stainless steel. Now I am back to just hand tools and a small drill press at home. The ability to cut and bend metal parts came in very handy. Having everything on hand is nice, but expensive. So, you invest in a membership to one of the community fab shops, such as MakerSpace, Fab Space, HackerSpace, FabLab, etc. They have the equipment and tooling. You either take the classes if you're not familiar with the equipment, or an exam to demonstrate that you know what you're doing. Or, you impose on your friends and accomplices to let you use their machines in trade for whatever. This has been an ongoing project for about a year so far. We paid for all the CNC hardware with the first job. The owner of the machines is a retired machine shop owner, so expertise is not a problem. http://802.11junk.com/jeffl/pics/CNC-conversion/index.html I did all the CNC wiring, troubleshooting, setup, sheet metal, 2 - 3 phase conversion, some electrical stuff, etc. The owner did the mechanical stuff. No need for a Rotex punch. We just mill the holes. Unfortunately, the mill is down right now after blowing a spindle bearing and shredding a Delrin gear. Plenty of other toys to play with meanwhile. I enjoy doing some simple projects, but would rather work with the components than the mechanical part of construction. I would rather do the mechanical stuff. Despite the BSEE and a life working with RF, I get bored easily and am better at the mechanical (and chemical) stuff than the electronics. While I do put the connectors on the coax and other cables, that is a chore just to get signals from one place to another and time I could be doing something more interisting to me.Spending several hours making up cables for a duplexer is not fun, but tuning it and getting the repeater to work is fun for me. I just sold my Motorola MSF-5000 440Mhz repeater and have un-volunteered to NOT work on the local radio club repeaters. No more repeater building for me: http://members.cruzio.com/~jeffl/k6bj/K6BJ%20Repeater/index.html (From about 2003). -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
