Thanks guys... I am getting into what I call "Twisty - Twirly" ornamental iron work and need a good mount for the bending column. Figure there's gonna be lots of torque on it with a powerful bruiser such as myself behind a 6' bar. Ya right! LOL

I use quickrok all the time. Stuff is the greatest.

In the old days we used to use PourStone, same as quickrok, for anchoring bolts. That was before redheads and other expanding anchors got to the stage of efficiency they have now.

We'd drill a five eighths hole. Pour it about two thirds full of pours stone. Then slip in a piece of half inch all thread. An hour later it was a done deal.

I have a little giant fifty pound hammer anchored with three quarter inch read heads without a problem one. As for the bending of steel into scrolly stuff. Make'm red and you will only need a hammer./w3tcompact/icons/laugh.gif

You might also consider using what I use, a Remington 476 Powerhammer. About $20 at HD or Lowes, it uses 22 blanks to drive special nails into concrete, up to 3" long I believe.

I used it to anchor an interior stud wall for an office I was building and they worked great. Many others have borrowed it and all have had positive results. Very easy to use.

wroughtn_harv,

How deep did you run the holes? I'm contemplating installation of a 30' tower for my TV antenna, would this stuff be suitable for the bolts? I'm sure the tower would be in constant motion with the wind and all.

Hmmmmmmmm, that's a good question. The kind that is deserving of many more questions before one commits to an answer./w3tcompact/icons/laugh.gif

If you're only attaching the base of your antenna to the concrete and it's going to have sufficient down guys then I'd use three quarter inch holes as six inches deep with five eighths inch all thread. After all. The bolts under these circumstances are only going to face shear load. The down guys are going to take the twist loads.

But if it's a free standing piece of steel and it's only support is the attachment to the concrete I'd go a totally different route. You'd need a pier hole. Since a telephone pole is a good parallel situation I'd suggest at least six feet deep. If it was me and I had the capability I'd go deeper, just my way.

I'd want good rebar in the pier hole. I'd want the studs coming out of the pier to attach to the base plate to be secured to this rebar.

Of course if the pier is sufficient then the next point of concern would be the plate attaching the pole to the pier.

A good parallel to consider for that situation would be to look at light towers in parking lots. Their system seems to work just fine.

Of course this is all probably overkill. But then you should only attempt to protect what you care about from damage if there was a failure./w3tcompact/icons/laugh.gif

They can have my Remington 476 Powerhammer when they pry it from my cold, dead, . . . errr, maybe I should be careful with it. It's not a toy./w3tcompact/icons/wink.gif

Are you serious?

Are you serious? 
Yep. I saw it on This Old House. Good ole Norm had to be licensed to use it.

The powerhammer is very dangerous, like when you have your thumb on the top on it and hit it with a hammer.

Seriously, it would be quite hard to use them as a weapon as the you have to hit them quite hard and straight on for them to go off, cannot imagine trying to do this while trying to aim the thing at something other than the floor.
