I make and engrave quite a few ornate items of blued steel. Most of
them are flush inlaid with platinum, high karat gold, or fine silver.
One of the problems I have is in the “cleanup” of the extra precious
metal left above the surface of the steel.
After reducing and trimming the material as far as possible with very
sharp flat gravers and scrapers - sanding is the last step One of my
solutions is to glue abrasive papers onto wooden tongue depressors
(=C2=BE" x 6") with double stick tape to make economical sanding and
polishi ng sticks.
Since these sticks are generally warped a bit, stick the abrasive
paper onto the convex - not the hollowed concave side. Mark the
concave side with the grit number.
I use a wide variety of grits beginning at 320, running to 600,
1,200, 1,500 , 2,000 - as well as 2/0, 2/0, and 4/0.
Some have very thin hard leather or cardboard impregnated with
various polishing compounds
