Who'd have thought... Mark gummy metal with a sharpie...

I just love America and youtube and the awful influence they have on people.... there is not material property known as 'gummy' its ductility which can also be combined with a few other properties like Plasticity. I wish these morons would go back to school and learn some engineering basics before they post these garbage terms that mean nothing. These are basics you learn in the first months of being in the trade, so what were these guys doing? Wonders.......

No offense meant to you guys here that use that term because you have only got it from youtube or others who have got it from youtube via people that have no physical materials knowledge it appears.

I wont be trying the technique all the same.


Same as the word 'tram' that's thrown about all over the place thanks to America and youtube. How does the word tram relating to squaring a head? Thats why we call it 'clocking the head' or 'squaring the head'..... because that makes actual sense... I just hate to see my trade watered down with wrong terminology arghhhhhh!
