Everyone needs a hardness tester.

Wow, that is very nicely done!

I spent some time working on a homebrew Vickers type tester and cobbled up a few proof on concept attempts a while back. But this is a much better approach for most of what I would want one for. Well thought out, well executed, and a great presentation of the theory.

Thank you for sharing all of your work in such detail. This will be on my short list of projects I think. I have a knife maker friend that would love one of these, I expect I will be making two of them...

Thanks again, your posts are always very informative.
