Buy 1 Get One Free Ikea Shelf Hack

For $60 I picked up an "Expedit" shelf from Ikea, it turned out to be too deep for where I wanted it...soooooooo
 
Good excuse to cut stuff!

I cut it down the middle and wound up with two 8" deep shelves that fit perfect.

Note: the backs of the new shelves look very unfinished, if that bothers you don't cut it! Up against a wall you cannot tell.

I used the shop and great table saw at http://makerplace.com/ to do all work.

Mark each shelf top/bottom piece, and upright on the center. I wound up taking out a shelf and not using the bottom piece for a different look.

With a good quality, high tooth count blade, use a table saw with properly adjusted rip fence to cut on your center marks. If chipping occurs try masking tape all along where the cut will be.

Now you have two piles of identical pieces, 1 pile for each new shelf. Assemble each shelf with ikea hardware.
The backs of the shelves now need some support, I added finishing nails through the uprights into the shelves.
Use long screws to attach top/bottom portions.
