Weak metal heads

<< < (2/2)

possum:
The heat treating is really simple with a magnet.  Just heat the steel til the magnet no longer sticks to the steel the then quench it in oil, vegetable, motor and my personal favorite, transmission fluid.  Then use a torch to temper it.  You want to polish the metal with sandpaper so you can see it change color, the heat it up until the edges turn a straw color.

Kegan:
It was just a little experiment (I've got some better metal for points), but it worked. They came out more of an elongated "Z", but it didn't wanna bend. I don't need them, but it is still nice to know that I can do something with what's lying around :).

Robinwho:
Use a torch and heat them until red then soak in ice cold water immediately and see if the metal stiffens.

MattE:
If your metal doesn't have any carbon in it, you can't temper it.
