Second the use of sulfur. Used by my grandfather, a blacksmith, old style. He always had a special melting pot filled with a lump of solid sulfur. He also showed how to do it and some old application
Correct, it is a Universal Aluminum tower. Self-supporting it should be able to take up to 85 mph wind. With the guyes it is able to take 135 mph, something that made it easier to convince the local
remember that sulfur reacts with iron to form SFe a solid and hard compound. At long as the sulfur doesn't get all the way through the steel rod but only a small fraction you will have a very long la
I believe K2TTT put one tower up using nothing as a base, just the tower standing on a small plate, resting directly on ground. Yes, it is (was) guyed. Dave, am I correct? Hans - N2JFS Why use Rebar
Sorry Dave, I meat "K1TTT". I don't know Jay and I hope I didn't make a stir. Hans - N2JFS K2TTT is Jay, I don't know what he has done. But I used to have a left over field day tower that was 60' of
I don't see any problems with screw anchors. Anyone what havae had any problems with them The one I use are, according to the manufacturer's spec., good for a pulll force of 14,400 # in undisturbed,d
If I understand you right, the screw anchors should be replaced at about ten years interval. Needless to say, if something fails due to corrosion or what-have-you it will break, that's what maintenan
I understand that. I think that if replacing the screw anchors every 10 years could prevent such a disaster I don't see that as a big problem. Not replacing them take a chance, well... . No, I will n
I'm not ever sure you would be able to remove one, especially if it is a little damaged by corrosion. My idea is to "just" add a new one by even the slightest suspicion that you have an inferior anch
Tom, I can't say this is the right way but it worked for me. Flip through the pictures and you will find how we simply banged on the anchor and turned it a much as we could. A new hit and you could t
I was recommended but Universal to use galvanized bolts as the SS are not available in high enough grade. (I don't remember now what grade they recommended.) In my mind I will replace the bolts in a
Patrick, It is very obvious that if we can keep moister out, no corrosion will take place, that's valid for almost all applications. The problem is that RTV application is not a long term solution. I
You think that they could have the decency to clearly explain that in their catalog even if they had shown the picture. The top name is "clamp-on" after all. Myself, if I was in charge, would be "hap
Jim, I didn't say that they treated you bad. They did, though, misled you with the faulty catalog page. It appeared as you would get more than double "bang-for-the-buck" when it turned out not to be
Gentlemen, I just wonder if, instead of digging big or small holes in the ground and filling them with concrete, it would be possible to drill down a number of screw anchors (minimum 4) and make a ba
Norm, Use a three terminal regulator such as MC7812. http://www.onsemi.com/pub_link/Collateral/MC7800-D.PDF Select the TO-220 version (MC7812T) as they can be mounted with one screw and can handle 1
Larry, I was required, in order to get the tower permit, to provide "adequate protection of the tower for unauthorized access". I put together three panels, four (5) feet long. The cross piece, that
There are attorneys specializing in this. They will be able to answer all you answers and also give you good advice what your contract should look like. There should, for example, be a paragraph of w
If i understand it right: You use the shield as one conductor for your sensor, which need three wires. The only way, what I see, is that you make sure the sensor is NOT connected to anything, that is
Wonder what base they need. I don't think a 4'x4'x7' piece of concrete will do. Hans - N2JFS I found this on Digg today and immediately thought 160m. And Big Berthas. THESE GUYS BUILD THE WORLD'S TAL
