I gave up on the 'perfect post hole' rule for a week and my work got faster
Everyone says you need to dig each post hole exactly 36 inches deep, no matter what. I was setting a line of fence in a really rocky part of my town last month, and hitting solid rock at about 28 inches on half the holes. The usual fix is to rent a breaker, which adds time and cost. So, for a 50-foot section, I just set those posts at 28 inches and packed the heck out of the concrete, making a wider base. I was sure it would fail. A big storm came through two weeks later with crazy wind, and that section held just as firm as the deeper ones. It made me think we might be too rigid with the rules sometimes when the ground is tough. When have you all adjusted the 'right way' because the site forced your hand?
