Bird, you are thinking exactly the same thing I was on whether the post bent, or if it just moved the soil. The answer to your question is a good "I don't know". /forums/images/graemlins/confused.gif
Eddie, I love the stone work you are doing. I have a scalloped shaped brick wall around a parking area. I was really wanting to use the stone like you are for the "posts". However, I was talked into just using brick. Are you running any electricity to your sign? I ran conduit through my wall and up to the top of my posts so I can put lighting on them, but can't find lights I like.
I was wondering what you used for an "every day" gate. The gates that come from the vinyl fence makers are of very poor quality and design. I can pretty well say that they flat don't work. /forums/images/graemlins/frown.gif I'm trying to figure out how to line the vinyl fence with steel or something so it doesn't sag immediately. Even with all of the cross bracing they send and recommend with a vinyl gate, it saggs badly.
You said that you are using 5" steel tubing. Do you plan on a need to stop tanks? /forums/images/graemlins/grin.gif I've used quite a bit of 3/8 wall 2" steel tubing, and that stuff is really strong. I couldn't imagine how strong 5" is!
