DIY Relief Hammers & Chasing Tools
自制浮雕锤与錾刀：选材与热处理
标签：自制工具, 热处理, 碳工钢, 錾刀, 工具评测
工作室自制浮雕锤选 T8/T10 碳工钢，锤头车削后 780–800 °C 盐浴加热、水淬油冷，180–200 °C 回火 2 h，硬度 HRC 52–56——过硬崩口、过软锤痕发糊。錾刀可用废旧锉刀改磨：退火后重新开刃淬火至 HRC 58–62，走线刃角 45°、细部收口 60°。评测对比：意大利进口月牙锤吸振好但单价 800 元级，自制全套成本约 60 元；锤头与木柄配重比 2:3，可在柄内钻孔灌铅微调，击打手感明显更稳。
Make your own relief hammers from T8/T10 carbon tool steel: turn the head, heat in a salt bath at 780–800 °C, quench in water-then-oil, temper at 180–200 °C for 2 h to HRC 52–56 — harder chips, softer leaves smeared marks. Chasing tools can be re-ground from old files: anneal, re-grind, re-harden to HRC 58–62, 45° for lines and 60° for tight detail. Benchmarks: Italian moon hammers damp vibration well but cost EUR-level; a full DIY set is about ¥60. Weight the head-to-handle at 2:3, drilling and lead-loading the handle to fine-tune balance.
