Looks very functional, Cross.
I built a flat bottom one for tamping sand with the Bosch elec hammer but never needed anything for hole diggin.
In sandy spots (most of this region) you can dig post holes with a leaf blower
A wetback on the end of a mexican dragline with a green card hanging over his head will out work your contraption 2 to 1. Plus you get to entertain his senorita while drinking cold cervesa while you keep an eye on him. Once you get the holes dug, you pick up the phone and dial the INS. I sometimes get the idea you way overthink simple things.
You're defective.
