Roy, thanks.

Got my teeth into it!

However, it's incorrect being called a Chilled Plough, I assume that is an
abr'd Americanism that is misleading to us, & as I inferred it doesnt make
sense! Its not a whole Plough but a type of 'Ploughshare'. I should have
done a little more research too! It's not the process, its what the process
achieves of bonding two metals with giving two different degrees of hardness
using the Chilling process!

"The chilled Iron Ploughshare has a hard under surface, and the top wears
away, leaving a comparatively thin edge of hardened
metal. This resembles the natural provision in the teeth of rabbits.
squirrels and other rodents whereby the enamel remains in advance of the
softer portion of the tooth, keeping a sharp edge. (Knight.), Lloyd 's
Encyclopaedic Dictionary, Vol II, 1895."


Regards,

Mikey.
