Planishing Curved Vessels (kettle body
曲面器皿的打平（壶身/碗壁）
标签：曲面打平, 内壁支撑, 分段固定, 旋转走锤, 防塌陷
将壶身或碗壁套在形状相近的铁砧（如圆肚砧）外侧，或用内撑具从内侧顶住。沿圆周分 4–6 段逐区打平，每段打满后再整体转 15° 继续，避免局部过打导致塌陷。深腹处需在器内填沙或塞木芯支撑，防止锤击把壁打瘪。
Fit the kettle or bowl wall over a similarly shaped stake (e.g. a round-bellied stake) or support it from inside with a mandrel. Work the circumference in 4–6 zones, rotating the piece about 15° after each zone to avoid over-planishing and collapse. For deep bodies, pack sand or insert a wooden core inside to stop the wall being driven inward. ---
