I have a few Rockwell hardness test blocks that are running out of areas to test upon. I was wondering if I could surface grind them back to new? As they are scrap if I can't do this, what do I have to lose? If I get the exact same hardness reading before and after grinding, then I should be OK? I am assuming they are through hardened and if I keep everything cold when grinding, I don't see the problem if I am only grinding off a few thousands. Yes I know the test surface is polished but I think I can do this too on a surface plate. Eventually the block will get too thin after being ground many times, but I think I will be dead long before this happens.
What do you think? It seems a shame to scrap these blocks which are not cheap to purchase. I was getting ready to order some new blocks when I had this idea.
My Brown & Sharpe No.2 grinder is ready and waiting if the consensus is this may work?
