The biggest advantage of a CNC router is that while it works you can keep busy doing other things. Today, I was hard at work, welding up the tree armature for the sign. While I was busy welding, the router was working hard in the adjacent room, carving the sign faces we will soon require. I was interrupted a number of times by phone calls and visitors, took a lunch and two coffee breaks and at times wasn’t very efficient. The machine kept chugging steadily through the whole day and perfectly carved three sign faces. By the end of the day we had accomplished a good amount of work.
