Testing

[Allen-in-Sheboygan]

I have seen some complicated testing methods proposed, starting with a board and then making many error prone measurements. Instead:

Start with a known quantity of something like bread flour, say one pound. Run it through the separator, then weigh it.  Better yet, take what is separated out and run it through again.  Keep repeating this until a significant portion, say at least 20% has been lost.

This way, you know how "fine" the material is that you are testing with.  It would also be easier to use a "standard" material for testing by  forum members. 

It might also be useful to have a "standard" design that could be used to evaluate modifications.  Then we would all be comparing apples to apples.
