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.

I'm curious.

Of course I'm interested.
Very interested. Any toxic aspects to be concerned about? Laser friendly, I'd assume...
I'm interested...
Sounds great.
I am also very interested. Thanks sergio.
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?
Bruce
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
