Picture of Copper shutter caps
My home is about 150 years old and the wood shutters are original.
The shutters were recently painted and we noted that there was significant damage to the tops of the side rails where the end grain is exposed. 
Water penetrated the end grain and speeds the deterioration of the paint and the wood.
I needed about 13 pairs.
Caps that are available commercially did not appeal to me. They tended to lap the faces of the shutters a minimal amount and therefore used screws to secure the shutters at the top. This doesn't seem to be too good for keeping water out.
So, I decided to make my own.

Step 1: Materials and tools

Picture of Materials and tools
I utilized the following materials and tools:
 - Copper sheet (16 oz.), purchased from a roofing supply company
 - Copper nails, purchased from Home Depot
 - 30" metal bending brake, $59.95 from Harbor Freight (No. 67240) purchased specifically for this project, but will be used for others
 - Electric sheet metal shears, $29.95 from Harbor Freight ( No. 92148) purchased specifically for this project, but will be used for others
 - Tin Snips
 - Hammer
 - Pliers
 - T-square, straight-edge and thin tipped Sharpie

Step 2: Layout and Cutting

Picture of Layout and Cutting
I used a t-square to lay out approx. 3" strips from a 24" wide roll, marking the lines with a thin-tipped Sharpie.

Using the electric sheet metal shears, I cut the strips and then cut them to length (approx. 19 1/8")

I then used a straight-edge to lay out the bend lines for the 1 3/8" wide x 17 1/2" long shutters. My overall 3" x 19 1/8" copper strip allowed for approx. 3/4" overhang or face on the cap.

I snipped the ends of each strip at locations which would be the ends of the front and back faces of the caps.

Instead of using nails to attach the copper caps, we use a dab of caulk or 3M's adhesive mounting squares at each end on the top of the shutter. This can easily be removed with a putty knife when you want to paint the shutters and the copper doesn't need to be drilled which could allow water penetration.
Also if you don't want to take the time to make the caps yourself, you can buy them with as much reveal on the front as you want at
