    Change to grinding wheels that grind cooler, like a big bucks CBN wheel.

    Acid/copper bath will self plate onto steel but it won't stick very well. Especially if the steel contains chromium and/or nickel. You'll be able to wipe it off if it doesn't flake off as soon as you touch it to a grinder. I would set up a small alkaline plating bath with a D-cell battery. At least it will stick.

    Oh yeah, and the part does have to be absolutely void of any oil including finger prints.

    Sulfuric acid as root killer? I think you might have it backwards. Sulfuric is often labeled as copper pipe cleaner or battery acid.

    In my local store the copper sulphate (one brand) has it in BIG letters across the product, and "root killer" smaller.

    In the US they aren't sold in the big box hardware stores by name to my knowledge. If you want sulfuric (sulphuric) acid you buy "root killer". I don't remember what they sell copper sulfate as.

    An older issue of Machinery's Handbook recommends dissolving copper sulfate in 4 oz. of distilled water (as much as it will take) followed by addition of 10 drops of sulfuric acid (of unspecified concentration).

    Copper Sulphate is also known as bluestone.

    Mixing copper bits or copper sulphate will give you the same effect, maybe how thick the plating is may be different??? It may take a bit of time for the acid to break the copper down, again????

    This thread is producing some interestingly vague and unfamiliar phrases. "decreased Patrick"? "ore water?"
    I did find bulk copper sulfate at Home Depot. The smallest quantity cost $13. It was right on the shelf above the sulfuric acid which cost $9.

    I have time. I will just put some sulfuric acid in a jar and add copper shavings until no more dissolve. I'm confident this will produce the desired strike plate on tool bits.

    Additionally, if mixing concentrated sulfuric acid and water ALWAYS add the acid slowly to the water. The other way will result in spattering all over you and whatever county you are in. I would just get some battery acid and pour it into some ore water.

    We use copper sulphate for a foot dip for our sheep. We buy it at the local farmers Co-Op by the kilo. In the USA there is a product for horses called Thrush X. It is copper sulphate. It is used on the foot to kill thrush, a foot rot in horses feet.

    That will take time, a copper sulphate solution will plate instantly on steel. Does not plate Stainless steel at all.

    And one more supply channel for copper sulfate is pottery places that sell all the ingredients like glazings and colors etc.
