Michael: Thanks for the reply. What we have hit is granite ledge, which is non poundable. I think the boring machine will be needed.

I used a skid steer with a hydraulic Ram for pounding/driving posts. I drove 5-6" treated southern pine posts 4 feet down with little trouble. Beside the End posts/anchors there is another post every 30 ft or so. In between the posts I planted 10 to 11 Tall spindle trees all secured to 4 layers of High tensile wire spaced every 2 ft. This anchoring has been in the ground for 4 years now and is quite stable.

We are hitting it 18inches down, surely not enough to anchor a post in the soil. One idea we have is to drill a 1&3/4 inch hole in the ledge and put a 12 foot galv steel fence post in, but it is only good for every other one because of its strength to bend when you use more than one. Experience or ideas ????? Thanks, Frank & Bruce Carlson Franklyn W. Carlson, Pres.
