I've seen homemade dirt/compost sifters that sound sorta like something that might fit the bill.

The two types I've seen:

1. flat screen

2. trommel/tumbler

The trommel/tumbler I saw was made from old bicycle rims that were covered in screening material (looked like a large cyclinder). He then rotated the tumbler with a motor and drive belt.

The screen I saw was mounted on casters and pushed/pulled with his jigsaw.

There are a few clips on youtube. Pretty neat stuff.
