There are a lot of things about guitar building that I have yet to learn. One thing I do know is that taking your time building a neck is a worthwhile investment. Wood is not as unpredictable as some folks might like to suggest, but you have to know where to look. Years ago I did some research on how necks in their raw and finished states behaved over time. My tests were conducted on two separate occasions and each involved a test group of ten necks along with a control group of an additional ten in a climate-controlled chamber. Every neck was measured daily for three months with electronic equipment capable of a resolution of 1/10th of one degree. Both times I achieved similar results. I’ll spare you the details, but my conclusion confirmed that proceeding slowly over time was the best way to build a stable instrument.
Today I’m taking a neck that has been in progress for several months to the next level—the rough carve. As you can see, the fingerboard has been bonded on, but is still flat. The first step is to make some radial marks on the shaft with a pencil, which allows me so see wherre I’ve been. This process is repeaded several times as the neck is broght closer to final shape and size. I probably could do without this step after all this time, but I still do it out of habit. I’ll use a cabinet scraper to bring the back of the neck to within .050″ of its final dimension, then back on the shelf it goes. By this point, most of the movment has taken place, but any last twisting will be taken out when the fingerboard is radiused in eight more weeks.
