Many people ask how to make a neck because they want to build one themselves. I encourage that so I made a video. It is incomplete but shows the steps needed to do it. Over time I will add the remaining steps to the video. When I began I made them 100% with hand tools but found no matter the effort that accuracy and repeatable suffered. Hand tools are a fine way to go for one off type of guitars but a CNC is the only way to go if you need repeatability.
