Those screens look fairly small, but I don't know what the mesh-sizes are in inches.
I use 1/4 inch and 1/8 inch screens primarily.

I think they would be ok for screening the fines out of Turface or calcined DE, the dust out of granite, and they're likely ok for the low (small) side of bark fines, but you'll probably want at least 1 larger screen for the bark - 3/8 or maybe even 1/2" would work as your largest screen.

I have a number of tools by Joshua Roth, a very respected manufacturer of quality bonsai tools, so the price is a fair one.

Sorry to be so confused about this screening thing. I think I've read about a dozen threads about this. Could you guys clarify what you use each of these sizes for one more time? I think you're saying you use fine screens like these (described as 1/10th to 1/4 inch wide) to screen out fine particles in Turface that you don't use in the gritty mix. In other words, you discard what goes through the screen. Then you use a larger screen of up to 1/2 inch to screen bark for either mix, and you only use the bark that goes through the screen in your mix, discarding what stays on top. Is that right?

Best for:

The 5:1:1 mix

Partially composed pine bark in dust to 1/2", uncomposted works fine, too

sphagnum peat - lumps broken up - I push mine through a 1'2" screen

coarse perlite, if available (if not, medium is fine)

Gritty mix

Pine bark screened to 1/8 -3/8 (some 1/2" included is ok if leaving it in eliminates an extra step)
or
fir bark in 1/8-1/4"

Turface screened over insect screen (fines that pass through the screen used elsewhere)

crushed granite - Gran-I Grit in grower size or #2 cherrystone. A brief screening over insect screen to remove the dust. Particle size of these products is usually about 1/8-1/4

The idea is to keep the particle sizes of the inorganic fraction of the gritty mix as close to 1/8" as possible. The bark should be a little larger to allow for some breakdown over 2-3 years.
