uncrichie Posted September 28, 2013 Posted September 28, 2013 (edited) Hi everyone, according to the usual charts 2FA powder should fall through 4 mesh and rest on 12 mesh. I just looked at some 12 mesh screen offered by McMaster Carr and they list several by wire diameter which gives quite a variation of opening size. Which should I choose? Thanks in advance.

AdmiralDonSnider Posted September 28, 2013 Posted September 28, 2013 According to a mesh-micron table I found 12 US mesh show an aperture of 0.0661", you probably best choose your material based on this value.
