Thank you to all who have answered my questions regarding microfacetting
the pitch lap. I will add microfacetting to my list as my work progresses.
I have one other question for those in the know.

If, in most cases microfacetting makes all the difference during polishing
/ figuring as some folks have mentioned, what about this idea (I will be
trying this myself, but I was just curious if anyone else thought of it as
well):

wire lath used for plaster walls and anchoring thin-set (for those who do
home improvement) is made with a rather sharp open "weave" to it
(about 1/4" - 3/8").  Has anyone used this to press a pattern
into a pitch lap, either by itself, or with a microfacetting screen? By
itself, it could be a "midway point" between larger facets and
microfacets, without the need to use a microfacet screen (I use that term
to encompass the many materials that fit into this category). The wire lath
is pretty sharp (meaning it will produce small cuts in your fingers), and
would seem to cut more definitely into the pitch while pressing. It would
also produce a diamond pattern throughout.

I realize there are probably many ways to make microfacetting work, but I
was just curious if anyone has tried this particular method. If not, I will
let the list know of my results.

Thanks again for all your help,
