How the Classical Guitar is Made
Adjust the nut and bridge to suit the actual guitar

Let's have a look at how the cow-bone nut slides into the guitar.
After the guitar is assembled, the shape of each guitar may vary by one hundredth of a millimeter. To overcome this, the nut and saddle need to be adjusted to suit each particular guitar. The nut should be leveled flat and the cow-bone shaved so that its height and shape fit the guitar perfectly.

Adhesive is not used to attach the nut and saddle. Instead, they are wedged in firmly for a tight, snug fit. Six slots should be chiseled for the strings, the tuning keys attached, and the strings tuned.
