Curvy Shelf

This shelf is made of a 0.90in x 7in x 8ft section cut from a 0.090in x 4 x 8 Non-fiberglass Reinforced Plastic (NRP) sheet intended as wall panelling which I purchased at Lowes.  The shelf supports are cut from a 1in x 8in x 6ft (0.75in x 7.25in x 6ft) piece of pine.

List of Materials:
One sheet of 0.090in x 4ft x 8ft NRP Waterproof Wall Panel
One 1in x 8in x 6ft (0.75in x 7.25in x 6ft) piece of pine
Three corner braces
Wood screws to secure top side of shelf and corner braces into wood supports
Sheet metal screws to secure underside of shelf into wood supports
Sheet metal screws with anchor plugs to mount into drywall
Sandpaper
Drill

I used a jigsaw to cut a 7in x 8ft strip from the 4 x 8 NRP sheet.  This forms the continuous shelf strip which is flexible enough to bend to the shape shown but strong enough for light duty support like those CDs and DVDs you don't use anymore.  To make the shelf able to support more weight, use two strips of the NRP together and/or fender washers on the screws to prevent them from pulling through the NRP sheet.

By the way, if like me you make the mistake of cutting your strip such that you accidentally chose the portion of the panel that the label stuck to, it can easily be removed with WD40 and razor blade or thin putty knife.

I used three different types of shelf supports:

Three 7in x 7.25in rectangular supports.  I added the middle one last after hanging the shelf  because it gave a little more support and served as a bookend.  The 7in side should fit against the NRP so that the support is flush with the shelf and so that the wood grain points out horizontally giving the shelf a better appearance.

Each rectangular support is attached to the wall using a corner brace:

Two 7in x 7.25in cut-away supports:

Two 5in x 7.25in small arch supports:

The cut-away supports and the small arch supports are anchored to the wall using a deep counterbore with a 3/8" to 1/2" drill bit.

You may find that have to play with the spacing of the supports, but I used the spacing shown below.  The diagram displays how the shelf is assembled prior to mounting it on the wall.

The left side of the shelf curves upward and around to form the circular portion which has an approximate diameter of 2 feet from top to bottom.

Of course, part of the point of this shelf is that it is flexible and can be shaped in other ways.  For example the configuration of the shelf could be changed from the horizontal one I have shown to a vertical one in the shape of an S.
