I'm almost embarrassed to post this here because its so simple...
We had a need for a wood rack near the house and I found a really simple way to do it courtesy of Instructables.
Materials
Three CMUs
Two Landscape Timbers
Two 2x4x8's cut in half
It took all of 15 minutes to set up (I had to move it a bit), and will hold about a solid facecord of wood.
Beware the other head of science - it bites! Nibble on this message:
