Once the carbon fiber was applied to the guitar body, the neck needed to be attached. To attach the neck to the guitar, a neck mounting plate and screws were used. The screws were able to fit through the pre-cut holes in both the guitar body and the neck. As seen in the picture above, the plate attaches to the back of the guitar with the screws going all the way through the guitar and into the neck. One the neck was successfully attached to the guitar body, the testing could begin.

​

Because of the lock down, the guitar was unable to be finished so the strings were unable to be attached and the originally testing plan had to be modified. To simulate the force of the strings, tests were done at multiple locations on both the body and the neck. These tests included pushing, pulling, and bending to see if the guitar could withstand the simulated forces of being played.

​

The testing procedure was done by starting at one location, applying the different forces, and the results were recorded in a testing spreadsheet with a pass/fail grade. If all parts did not move or break, the test was considered a pass. Extra bending tests were done near the neck cutout since that is the critical location on the guitar. 

​

Both the neck and guitar body were able to handle all the testing loads that were applied. The neck cutout was especially looked at since that is where the neck is attached and also where the least amount of carbon fiber is. The neck cutout was able to withstand each test that was applied with no movement from the neck or screws.

​

The biggest testing issue that occurred was having to completely change the testing plan due to the lock down. Initially, the plan was to completely build the guitar and test it by plugging it in and playing the guitar. Because of the lock down, the guitar was unable to be finished and the testing plan needed to be modified in a significant way.
