These are pretty easy to concoct and a very good attention getters.
First fold a piece of paper(as big as your piece of wood) in half then draw
and cut out 1 side of your plague. When you open it you'll have a full pattern
for your plaque. Now place your pattern on the wood and cut it out.
Now router the sides of the wood and drill holes for the buttons. The next
step is to center your letters and trace the outsides. Now cut a strip out
of the center of the lettering outline. Make sure you don't cut out the entire
center, since you will need to have a means of mounting the letters to the
plaque. This hole will allow the light to pass through and will allow the
edges of your lettering to glow and be noticed.
To mount the letters, first place a piece of wood or metal under your letters
to create a even gap between the letters and the plaque. Now screw or nail
the letters into the plaque.
Now paint the plaque and letters, add the clamp light behind the plaque and
mount them to your cemetery fence columns. If you can mount the light top
the column, then leave a gap between the plaque and the column and this will
allow an eerie glow around the plaque as well as the letters.
You're ready to go.
