Group 1 2012 Gate 5
In this gate, we finalized our findings and reviewed our process and presented them in a technical report. In addition to a written report about the project, we also presented a proposed revision discussed in Gate 4 to the class and instructors.

Technical Report
Executive Summary
Product Analysis Summary
The analysis process for the piano primarily focused on a dissection and reverse-engineering of components and systems. The following is an overview of the main stages of analysis we performed.
Dissection and Reconstruction
The parameters of the analysis project required us to disassemble the piano down to its base components, and later reassemble the piano back to its original working functionality. In general, both disassembly and reassembly were completed quickly and without major setbacks. We were somewhat surprised to see that virtually all of the piano was held together with Phillips head screws and glue. This made the disassembly and reassembly considerably easier than initially anticipated.
Product Disassembly
The following is an overview of the disassembly process. For an in-depth review, see Gate 2: Product Dissection.
Product Reassembly
The reconstruction was a relatively simple process. Since group members already understood the subsystem layout and interaction, the rebuild went smoothly and quickly. Only two group members were needed for the reassembly. The reconstruction is covered more thoroughly in Gate 4.
Idunno. Pictures. That video if it turned out well.
- Put tons and tons of pictures in here
About screwdriver as the only tool
A bit about taking out the action. -taking apart the action.
Same for pedals.
Why we left the strings and plate in.
Analysis Process
Chris, write whatever you want as long as the bullshit to cynical realism ratio doesn't drop below 2.
Component Summary
Our analysis revealed that the upright piano can be generalized as consisting of three main components: the cast iron frame that holds the strings in place,the action that translates key depression into hammer movement, and the exterior wooden housing that supports and protects the other components.
