    Engraving on metal compound $20 for one year

    For those that are interested in a low price compound to engrave on metal check the picture I have attached, it is a polished Hard drive metal disk.

    If enough people are interested I will post the ingredients to make the compound.

    How scratch resistant is the marking?

    What if only one person is interested? How many have to be interested in order for you to post the recipe?

    Very interested. Any toxic aspects to be concerned about? Laser friendly, I'd assume...

    as with any compound you will have to read the warning labels on the containers. I have not had any trouble in the past year that I have been engraving with this concoction, it can be easily removed with a moist cloth or water.

    Not so secret!!!

    Are you all ready to run to the store????

    you will need the following:
    one bottle of Mothers Chrome polish, I paid $5.99 for it.

    you will also need the following
    Calcium Sulfate Hemihydrate
    Calcium Carbonate
    and Crystalline Silica

    or instead of the three ingredients mentioned above, you can go to the Home Depot and buy Plaster of Paris the Dry Mix for under 12$ (if I remember correctly.)

    Mix ratio by weight: 1 part Plaster of Paris, 1 part Mothers Chrome Polish, or to make it easier, mix till you have a ketchup like consistencyI mix mine in 2 oz cups, 4gm of Dry mix and 4gm of Chrome polish at a time, this is
    good enough to cover a 4x4 inch area .


    How to engrave: I use very little air pressure not to blow off the compound of the part being engraved I usually
    used 80% power and speeds ranging for 5% to 10% on the M350 depending on the metal being engraved.


    Please post your results and if you like to add anything to this thread, also if compound flakes off, try using 1 or 2
    drops of soap in the compound.

    Good luck to all and make sure to read the WARNING!! labels.

    Sergio,

    You mentioned a ketchup consistency, how thick is this formula to be "coated" on the metal. Also, does it need to be completely dry?

    How

    I have to ask, what in the world made you ever think of mixing Plaster of Paris and Mothers Chrome together??

    Very interesting and ingenious.

    Thank you
