This week in guitar building we began by using a round-over bit on a router table to round out the edges on the guitar body, making sure to keep it moving and go against the rotation of the bit to prevent burning from friction and the body being pushed out of my hands. Next I began filing the forearm rest on the body, which took a really long time, followed by using the random orbital sander to smooth out the scratches from the file. I then flipped the body over and began filing and sanding the back side of the forearm rest, using the rounded side of the file because it was an inverted curve. Finally I used a portable spindle sander to smooth out the curve and cleaned up for the weekend.
