[QUOTE="aussiefarmer, post: 274733, member: 5729"] Just to add to the hardend metal side of this , when i made my pick i only used thick checker plate , so mild steel , so i run all my welds in one go and had it glowing red then dunked it into sump oil and the quick cooling and carbon in used sump oil hardends the steel. It is guess work on how hot and how soon to dunk it , as this is the key in to soft or to hard. But any way its all fun , over welding a plow disc will also make the steel mild again , but the pics on here look fine in my book. I posted pics of my pick in "today i made " if anyones interested or i can repost em here. Nice picks by the way look good. [/QUOTE]
