Wire inlay isn't as hard as it looks. Make a couple of cutting chisels out of Hack saw blades 3 mm to 5 mm wide. The hacksaw pieces should be 3" long and are to be tapped with a light ball peen hammer. To draw the outline of the wire inlay insertion , make a brass sheet metal inlay and draw around it with a #4 hard lead pencil , then start with the hacksaw chisels and ball peen. Once the outline trench is cut , slightly deeper than the width of the inlay ribbon, begin gently inserting the wire inlay into the trench using a Small ball peen hammer. Shape the wire as you go. I put epoxie in the trench as I go , and continue the insertion with glue. I prefer putting brown dye in the epoxie , so the trench with the wire are one. There are a couple how to do it books , showing how folks do wire inlay. Nothing is written in stone.
