Mike if you wanna drop me your address I'll send you a strip of this cs 100 in an envelope . I'd like your opinion of its workability The cs100 might be better carbon is 1% -
This is the link to the supplier https://springsteelstock.co.uk/cs70-c67s-carbon-steel/ -

This set lever seems to working ok unhardened Nickelsilver, might it deform if i leave it that way ? I tried that method of annealing, it wasn't great but i was using unknown steel quality, old imperial feeler gauges. -

I found this from a while back CS100 seems fine, but at around 500 Vickers it's not quite as hard as "blue" steel, but still harder than annealed. I'd try to find annealed (the post above has a U.K. supplier of small quantities). -

As an experiment i was thinking of not hardening it to see how it fairs. Now that i have a complete template i could knock up another in half the time if this loses its elasticity. I might play about with a few pieces today to test their bending and spring properties. This was cs 100 the supplier quoted in annealed state, it was nice to work with files so I'm taking it thats its state. What you are looking seems like it would need annealing to work it. This is why i went for this stuff that cuts out that process, it was so easy to work.
