Monday: Today I worked on the working drawings for the parts that I will be milling with Luke. These consist of the crossbars for the picking mechanism, which will be made out of 1/8in aluminum. See corresponding picture for example.

Tuesday: Today, I brought in my guitar and figured out that the height of the solenoid covers are correct. At some point in the next week I will print these out of TPU so that they make better contact, but (as seen in the attached video), they work fairly well out of PLA. I also discovered that I need some form of shims for the bottom of the fretboard tray, as it is currently too short. 

Wednesday: Today I finished the working drawings for the crossbars that will be milled. See attached photos. 

Thursday: I did the math for the aluminum standoffs that will need to be made to attach the picking mechanism to the guitar. The need to be roughly 1.5" tall with #8 tapped holes in either end with a minimum depth of 1/2".

Friday: Today I figured out how much stock material I need, and discovered that I need more. I also helped Frederick with figuring out how much material he needs for his project, and began the McMaster order.
