 Our group for MAE 277 had the opportunity to familiarize ourselves with the corded Black and Decker Alligator Lopper. This particular device is a branch cutting and trimming device designed for homeowners and the upkeep of their property. It utilizes the technology of an electric powered chainsaw while incorporating a jaw which the user can manipulate open and close. When the user wants to cut a branch, they manipulate the handles and expose the chainsaw to the branch. By clamping the jaws shut around the branch, the user forces the chainsaw into the branch, cutting it. Through the product dissection, we learned that the Lopper was designed with a high level of safety which can be seen in its dual trigger system. Furthermore, most of the product was intended to be taken apart for maintenance or part replacement. This is illustrated in both the simplicity with which the Lopper was designed and also in the list of components the user may purchase online. Further analysis of the product gave us the impression that the components were manufactured using simple techniques that can support a high production rate. Furthermore the materials used in building the Lopper indicate that it was intended to be used in residential areas and would not withstand prolonged commercial use. Assembling the product reaffirmed our belief that the user was supposed to access and maintain most internal components. It also showed us that the product could be modified easily to improve its function and form. These modifications range from small subsystem modifications to larger full system revisions.

−	Before getting started on each gate, the group gates should be divided into different tasks for which each group member will be responsible for. One person will be assigned as the "Communication Liaison". They will be in charge of making sure everyone is knowledgeable about what is going on and who will do what tasks. There will also be a "Gate Manager" who does the updating to the wiki and final check of the uploaded information. They will work with the "Communication Liaison to make sure everyone is doing their work. The group should outline how they plan on tackling the upcoming gate. Based on group member preference, the actual work will be divided equally among the group. This will allow each member to pursue their own interests in dealing with the project. Revision will be a constant process and the group should meet a few times before the assignment date to make sure everyone is on track in delivering their assigned part of the work. The last few days before the due date the group should meet in its entirety and have a formal review of what has been completed so that it is up to the academic standards of each group member.

	During the course of this gate the group will disassemble the Alligator Lopper. The group will observe the different aspects of the Alligator Lopper during the dissection of the product, which allows them to obtain a clearer understanding of the subsystems and the interactions between components. Every stage of dissection will have its own level of difficulty to which the group will categorize and create a rubric representing each step. Some of the factors which will determine the difficulty ratings are the tools that are used disassemble the product in each step.

-'''Purpose'''
+====Purpose====
 In our group's attempt to further understand the inner mechanisms of our multi-purpose Alligator Lopper hand tool, we plan to perform reverse engineering and deconstruct the equipment to reveal its moving internal parts and subsystem interactions. Once we obtain the actual product, we can further examine its exterior and make assumptions about its limitations as far as movement, accessibility, and other similar characteristics. However, the bulk of our project requires us to disassemble the product. Based on pictures we have viewed online, we anticipate that we will use a wrench or socket set for the two main exterior bolts, Phillips screwdrivers will be required for the outer housing, and a set of allen wrenches could be of significant use when dismantling the subsystems within the housing. During the deconstruction process, we plan to arrange the disassembled parts in an ordered fashion documenting their purpose and its placement within the product's systems. This will make an easier task of reassembling the product after our dissection. Our group seems to be strong in understanding the technical workings of this piece of equipment based on photographs seemingly due to previous experience with lawn care devices. At least one of us has used a chainsaw a few times in their life so that experience and understanding will come in handy when trying to reverse engineer this product.
