Grinding And Polishing - Hi-Tech All-U-Need GLASS/CRYSTAL Instruction Manual

GRINDING AND POLISHING

STEP 1: ROUGHING
The 360# diamond disc is the coarsest disc that
comes with this All-U-Need. If you have less than
a millimeter to remove, we suggest skipping this
step and begin at step 2. The 360# disc is required
if you need to remove a large amount of material
from your work piece, or to remove glass left from
the punty. Install the 360# disc according to the
instructions on page 7. Remove material until you
obtain the general shape, size or depth of your
finished piece.
STEP 2: SHAPING
The 600# diamond disc will either create your
first intial shape, or if you started at step 1,
remove the deeper scratches left by the 360# disc
and attain the final shape. Install the 600# disc
according to the instructions on page 7. Remove
material until you have a look simliar to a surface
having been roughly sandblasted.
STEP 3: SMOOTHING
The 1,200# diamond disc will remove scratches
left behind from step 2. Install the 1,200# disc
according to the instructions on page 7. Proceed
to grind until you have a finely frosted surface.
A properly shaped surface is perfectly smooth
and satiny in appearance. Rinsed and dried, you
should not see any scales (aka dimples, facets,
flats, etc,) or scratches. Hold it up to a bright light
and look for deep lines. Scales are most easily
observed by watching the piece dry. Because
the "scales" will have deeper puddles of water,
they will evaporate more slowly. Wet your piece
and watch for this phenomenon. If you see any
scratches or scales, you may not have smoothed
long enough. If after additional smoothing you
still see scratches or scales, they are too deep to
