PSA: I was setting my post holes wrong for years and didn't know it
I was on a job in Springfield last month, putting in a basic cedar fence. The ground was pretty soft, so I was just digging down about 18 inches, dropping the post in, and tamping. My new guy, who used to work for a big outfit out west, was watching me. He finally said, 'Boss, you're not making a bell at the bottom, are you?' I had no idea what he was talking about. He grabbed the shovel and showed me how to undercut the hole, making the bottom wider than the top. It creates a concrete anchor that stops the post from heaving up in the freeze-thaw cycle. I've been doing this for eight years and never learned that trick. Has anyone else had a basic technique they missed for way too long?
