Back to this question.... I will have to buy a sieve - I believe I was
told
80 mesh.... Is that going to be fine enough?

If you are going to buy only one sieve, buy that 80 mesh. If you are
going
to buy two, get an 80 and a 120. For coarser than 80, you can always use
a
piece of (metal) window screening, or a screen material kitchen strainer.
I've worked that way for years.

Funny, I've never rubbed off my fingerprints though :)


If you are looking for an inexpensive source for sieve
material to make your own, the best place I've found
is McMaster-Carr. A 1ft square of most any mesh size
is in the 7-8 dollar range. I built a simple square fram
from 2x2 lumber and stapled the sieve screen to the
face of it, then gave the frame multiple coats of semi-gloss
interior latex to seal both the wood and the seam where
the screen meets the wood. Works great!

McMaster-Carr is at www.mcmaster.com. For an
80 mesh sieve I got part number 85385T869 "Type 304
Stainless Steel Woven Wire Cloth, 80 x 80 mesh, 0.0055 inch
wire diameter, 12" x 12" sheet". It was $7.24 one year ago.
No minimum order, no "handling" charge. I also got 4 other
sizes and the total shipping was only $4.25.

Hope this helps!
