Appalachian Trail Sign Modification Process 30 minutes passed from the first photo to the last. Of course I did plenty of tweeking of the guides and practicing in the kitchen first.
	These photos were taken at my home. This is not an actual active sign.
	A ruler is taped to the sign 3" below the tops of the new characters at the top of the sign. In this case 3 1/2" below the top edge of the sign. For lettering at the bottom of the sign, it would be 3" above the bottoms.
	The first guide is taped to the sign centeered on the 10"  mark on the ruler.
	The Dremel tool is used with the guide to route the 2 vertical lines to make the sides of the "N". The tool is using a 1/8" bit at a depth of 1/16".
	Here are the 2 vertical lines to make the sides of the "N".
	The guide for the diagonal of the "N" is taped in the same place as the last guide using the same tape.
	The diagonal of the "N" is complete.
	The guide for the arrow head is taped centered at the 8-7/8" mark on the ruler.
	The arrowhead is routered.
	The guide for the arrow shaft is taped.
	The arrow shaft is routered.
	This is the guide to the top of the AT symbol centered on the 7-3/4" mark..
	The top of the AT symbol is routered.
	This is the guide for the vertical part of the AT symbol.
	The vertical part of the AT symbol is routered.
	This is the guide for the horisontal part of the AT symbol.
	The AT symbol is complete.
	The finished product. Of course, if this had been a painted sign, the routered symbols would need to be painted with a fine brush.
