Building High-Tensile Fence requires strong Corner & End Posts - Black Locust post I cut & debarked!

This BIG Post is 3.5' into ground and I didn't have HELP or camera operator to film ME pounding Post. I have 2 more pastures to fence this Spring. I will get the Pounder on Video in Action.The Post was 104" (8.5 foot) Black Locust 14" in diameter. No Pointed End either! I have a Shaver Super Slide Positioning System with mounted HD-12 Post Driver. It is a Monster of a Machine!
