a friend told me about this JB Weld metal epoxy stuff that you put on metal and seals it up like a weld.i use 2 sections of chain link fence top pole for my mast witch is about 14 feet tall and i'm planing to put another 10 foot section on and he said to put it around the ends where the sections go together to give the mast more stability.does this stuff really work?73' Bluegrass KCD-40219 CEF#446 in Louisville,KY. |

JB weld is good stuff we used it to mount brackets on a steel plate and like super glue it holds good. |

i love JB weld, but the stuff you are talking about is nonconductive, so iti wont make a good ground connection between the poles. there are a lot of other products like this around. i would call a local welders supply store and ask them if they have a metal epoxy compound that is conductive. |

JB weld is awsome! As for the top-rail mast, how I did mine was where the 2 sections meet (male-female fitting) I put a wood dowel (about 14") inside then drilled 2 holes (1 above and 1 below the joint) and put in lag bolts.
As far as stability, assuming the male-female connection, if you guy it right below the connection(s) and one at top, you should be fine. I used clothes line for the guy wires and haven't had a problem with this setup for about 8+ years. |

i don't have the room for guy wires and as for the conductivity issue the jb weld will only be around the edge of the sections to keep them from comming apart it won't be inside them. |

Bluegrass,
If I were you I would drill a small hole in both the pipes right where they are connected to each other and screw a copper brade between them just for a good ground.

my i-max99 is dc grounded so it does not need grounding now i know grounding is always a good thing but i do what i can.the only grounding i have is a rusted 4 foot long piece of rebar driven about 3 1/2 feet in the ground with a thin copper wire thats around one of the mounting bolts on the antenna and attached to the rebar with duct tape.this has to be the worst grounding system in the world. |
