Do a search on nameplate paint stick
that should get you close --- paint sticks are the best way to fill engraving in pet name plates. I did a job a few years ago --- we made 1500 sequentially numbered ID plates for computers

I then tried cutting out a rectangle in the 16 guage 304 steel, I took 45 minutes to cut a 1 inch rectangle, but want to make sure I didn't damage the .25 end mill. At first I had it around 8000, and the oil was smoking, so I dropped the spindle down till it stopped smoking, 2200 rpm was magic number. I was going at .01 cut per rev to avoid any damage on my dirst attempt.
The end results were excellent. I need to find a way to take the sharp edges off the sides of the rectable piece, maybe just some fine sand paper by hand?
Side topic: what are you methods for applying paint to fill the text? I tried using a Qtip to dip the paint and fill the lines, then wipied the excess with a paer towel. I think there is a better way though, when it dried I had too much smear and had to use a solvent which affected the good paint in the grooves. |
