The other week, I picked up a couple of brand new (VW) skoda coil springs.
Being the scavenger that I am, my first thoughts were knives.
After staightening the springs I done a quick test to see how they hardened etc. I made a very rough but thin chisel type end on one of them and quenched in water (I used a friend's forge as it's bigger than mine, but he had no oil at his
) and then tempered them over the fire to a purple colour...not very scientific, but it was just to give me an idea of how they worked.
The end was ground to about the thickness of a bowie or camp knife, and then tested by cutting some 3/8" round and square mild steel bar. To my utter surprise, the edge wasn't damaged at all.
I then put it in the vice and proceeded to break it, the table lifted first and it took a good bit of pressure to snap it. The break looked like fine, light grey velvet.
Seems like some good stuff.:thumbup:
I appreciate that no one will haxe the VW/Skoda steel specs lying around, but does anyone have any ideas what steel this is likely to be?
Many thanks,
Ian
