Stacking Sieves to improve cheap grinder?

Hey,

I've just had a wandering thought. Some of us simply can't afford a good expensive grinder and one of the main problems with the cheap whirley-blade grinder is that it doesn't give a consistent grind.

I picked up a grinder for €20 recently and am very happy with it, for the price. But when grinding for my French press it does give a fine dust along with the required coarse grind. This tends to leave a muddier brew.

So I thought about a simple solution there... a 2-stacked sieve device. After a few google image searches here's the closest existing thing to what I was thinking (images below).

1st sieve: only allow grind < max-size to pass
2nd sieve: only allow grind < min-size to pass
Tray - catch the dusty grind.

The optimum grind would then be held in the second sieve.

Surely a simple compact kitchen version of this could be made cheaply.

What do ye think?
Does something like this already exist?
Should I just shut up and save up for a proper grinder?! :P

Dragons Den?!

By posting I'm already voiding any patent which I don't believe could be aquired anyway! :rolleyes:

Give it a go if you want my advice would be to save your time and money and pick up a grinder.

You would end up wasting a lot of time and coffee.
However, it probably would work.

Similar items exist for determining grind distibution profiles of grinders. An old fashioned alternative to laser diffraction.
