NEVER Hang a Gate on the Steep Side of the Run (A Carpenter's Way)

Every fence that fails on a hill fails the same way — somebody built it for flat ground. The rails go in level, the gap under them grows into a foot of open triangle at the downhill end, and the gate either scrapes the dirt or hangs where gravity wants it. The boards were fine. The ground was never consulted. This video walks the whole method on a real grade: stretching the string and measuring the honest drop, when a panel can rack into a parallelogram and when the grade is past ten percent and the bays have to step, the one rule for posts on a hill (plumb, never perpendicular), and where a gate can actually live on a slope — including the swing direction that digs a trench and the racked gate leaf that fixes it. In this video: 1.Why a level rail over sloped ground always leaves the wedge 2.Reading the contour with a string, a level, and a tape 3.Racking limits — the ten-percent rule and the panels that refuse 4.Stepped bays and the under-gap you close with ground, not lumber 5.Setting posts plumb and keeping the downhill soil a way out 6.Where the gate belongs and which way it has to swing 7.The mistakes that grow into gaps 8.Slopes that beat a fence entirely 9.The whole method in one pass What does the hill under your fence look like — and did the last builder ever put a string on it?
