With the LM MK3 coming out, we thought, what better way to christen a new machine than to build a fancy guitar?

In the final part of our guitar build series using the new LongMill MK3, Scott takes all the pieces we carved and puts them together to bring the build to life. This includes sanding and gluing the pieces, attaching the neck and fretboard, installing the electronics and pickups, and everything else needed to turn a bunch of CNC-carved parts into a rocking guitar.
