My youngest son was into blacksmithing - for 5 or 6 years I had to sit through blacksmith meetings - usually the only woman in the crowd - it is fascinating to watch metal being shaped by heat and a hammer and what ever tools a blacksmith comes up with - The coolest was to watch them forge weld a couple pieces of metal together
I think it is just another reason I have such respect for the amazing old sewing machines. I understand how much extra went into them compared to the newer stamped metal and plastic machines.
