Drilling out bolts usually isn't TOO bad, If you can get the broken 'thing' onto a mill. If it is something too hard for a carbide drill bit, then you send it to a shop with EDM or a tap burner (real
You forgot one MAJOR cost - Insurance! Your antenna that you certified to have a wind loading of X, and a wind survival of Y comes down in a storm, or even worse, is on a tower that comes down in a s
Against the sky, aka the upper part, and the antenna if you can get radome paint, I'd use ghost gray and compass gray - think the colors they paint fighters. The sky usually isn't blue, but blue/grey
Call your local steel supply house. 4130 (what we call Chrome Molly) tubing is a common item, and if they don't have it, it isn't hard for them to get One thing. You realize that say going to 2.5"x.2
Yes, they require different mounts. I have made more than one of these. Feel free to email -- 73 de KG2V Charlie _______________________________________________ ______________________________________
One option that works WELL (and in fact is what most Mil spec places use for any kind of BIG soldering where they can't crimp) is called Resistance soldering. Stinks for "Up the tower" but for the be
I mentioned resistance soldering - although this ISN'T a PL-259. watch the video https://www.youtube.com/watch?v=VfkJJlwgnf8 _______________________________________________ __________________________

Yep - Remember, your coax shield should be tied to the tower at the bottom AND the top. (Gee, yes you can carefully strip the outer jacket and bond, but easiest way is something like a PL-259 bulkhea
I think people are confusing two types of solder here. There are "low temperature" silver solders (Stay-brite is one) that are basically replacements for lead solder. These are the types of solder t
<snip>> For lightning protection (or any high current application), solder seems Dave, you are confusing "soft" silver solder with "Hard" silver solder aka silver brazing, which is explicitly allowed
...snip... I don't know, at least in the circles I hang in, almost everyone has a B tank or two hanging around, and a few pounds of silver solder, so cadwelds are "exotic" and having the gear to silv
The biggest issue with paracord, which I would not expect to be available in Cuba as it is a U.S. Army spec, is that it is what is called a dynamic line. It stretches when put under load. It is used

Another thing that works well for off center holes is called an "annular cutter". They look like a hollow end mill, are not meant for side milling, but drilling holes. I've seen the used with mag dri
Actually, that will work, but you would probably be better off with a bronze ring, or even better today, one of the many engineering grade plastics. Unfortunately, some of the better are crazy expens
I always thought that a bright supplier would find a "Compass", "Ghost" or "Gunship" grey paint that didn't mess up the electrical properties, and offer it. (or better yet, both) Do the boom in one
I thought that's what I said by spec'ing Compass, Light/Dark Ghost Grey, and Gunship Grey Light/Dark Ghost is the current 2 tone scheme on the F16, Gunship is the Current color of the F15E, and the
