Diamond Hand Pads
This
is part two of a multi-part tip on diamond hand pads. Click
here to go to part one.
Diamond hand pads are
ideal for finishing delicate pieces or reaching into areas that are hard to
reach with bulkier automated tools. They can also be used to grind and polish the edges of a
piece of glass, or even to help smooth out the top or bottom
surface.
Just don't expect the work to go as quickly
as with a wet belt sander or flat lap. Working with hand pads
is usually time consuming, but it also affords a feel and an
intimacy with the glass that's not usually possible with more
elaborate tools.
As with most grinding and polishing
operations, a typical job calls for using a succession of grits,
from coarse to fine. To make this job easier, diamond hand
pads are color coded, with each grit being a different color.
These colors can be different for different brands.
Rough grinding and polishing work often
starts with a 70 grit, then proceeds to 120, 220, and 400.
Usually 600 grit is about as fine as people use with hand pads on
glass; this won't leave a highly polished surface, but it will leave
a nice satin sheen.
