[QUOTE="aussiefarmer, post: 322809, member: 5729"] Just on tempering , sump oil is the oil of choice because of the higher carbon rate , welding and grinding and cutting destroy the temper so do the cuts then weld the handle holder on and dunk it immediately into sump oil the quick cooling and carbon in the used oil will give a degree of hardening , slow cooling after welding will cause a mild steel effect.
