Al,
Yes.

The breakdown.
24 bags of Clay King medium
15 bags Akadama medium
12 bags Akadama small
10 bags US pumice
10 bags Hyuga  (brown and yellow bags)
8 bags medium scoria (volcanic)
Kanuma sifted 6 or 7 bags of mixed sizes, a couple were partials.
I also had several prescreened 18 gallon tubs of prescreened/sifted small scoria! I also have a good deal of left over soil in the smalland large size ranges for next year- 7-8 eighteen gallon tubs.


Had to go count bags. I need a soil sifter, this represents the better part of five days work, but I am slow.

For that much sifting, you'd better with a dedicated tool rather than my little tool.
Rotating sifters, due to their simpler design should be far less expensive than oscillating ones.

The problem with the one above is that there is only one size but it should be easily fixed by an external screen.

An interesting home made contraption..........

That looks like a cheaper option.

The larger ones that I have looked into cost $1-2k so I emailed them, maybe this one is a little cheaper?.
