Well, after considerable thought and design, I've come up with a set of routing templates that can be used to recreate my complete Hambone jazz body design and do a few extra things too! The system works like this: After selecting, joining and thickness sanding a 15-16" x 21" blank the master templates (female) are mounted in register to both sides of the wood blank. Then precision fit male pieces are put inside the master templates and are use to rout the neck pocket, pickup recesses, and electronics cavity. One will also be able to drill and tap for different pot arrangements, neckplate choices, bridge selections, and string-thru designs. When all of the smaller routs are completed the master templates are removed, leaving the male templates for routing the body shape. I've even worked into the system templates for making knobs and additional blanks for experimenting with different necks, pups, and bridges. The whole system is designed to have a useful life of about 5 - 10 guitars, more if close care is used to maintain the condition of the templates. I'll be making the first one in the next couple of weeks and using it to build another bass. The templates are designed on the computer and will be precision routed with the CNC router table. Tight tolerances for repeatability are the goal. If all goes well I should have the perfect system to explore a lot of variations in a Jazz design.
