During the work period from December 11 to February 3, the team has worked up to Task 4 of Milestone 3 of the project. One of the most important tasks that the team completed in this period was getting in contact with the machinist that was provided by the Department of Engineering. The team was able to get crucial feedback on the design and its ability to be manufactured. The machinist gave the team some points to change and to be added on the CAD drawing so it can be sent to him. The team also made several purchases for the project such as the hoses, hose clamps, bolts/screws, the required heat exchanger, the pump, and hose fittings. The crucial parts that the team also acquired were the two plates required for the cold plate for the system. One of the plates was purchased from Morris Metals and the second plate was purchased from Metals Supermarkets. The team’s CAD file for the cold plate has also been altered with the feedback that the machinist asked the team to change. The task that is currently being completed is that the team will drop off the two plates at the building the machinist provided during the initial meeting so that fabrication can begin.

For the work period of February 4 - February 17, the team plans to obtain all necessary materials and components for the system. Now that the aluminum sheets have been acquired, the team will deliver them to the UH machinist to have them machined and prepared to assemble as a cold plate. The major milestone the team hopes to achieve is acquiring all required system components, aside from the completed cold plate. The team hopes to be prepared to begin assembly as soon as possible once the cold plate has been manufactured.

Over the next two weeks of Capstone II, Team 26 foresees a couple of obstacles. One obstacle that we faced is the fitting of all the components together. The hose adapter that we purchased did not fit with the hose size that we had mentioned in the bill of materials, but this is easily fixed by changing the hose size to allow the adapter to fit in. We have not done so as of 02/03/2024 due to the heat exchanger having just arrived as well as the water pump. All the components of the system have been acquired excluding the manufacturing of the cold plate so on 02/04/2024 Team 26 will be taking the heat exchanger and water pump to Home Depot to make sure that we purchase and acquire the correct size for the adapters and hose to begin putting the components together and making sure that everything fits and is well connected. The next obstacle we expect to face is the amount of time it will take for the cold plate to be machined. If the machinist says that it will take too long then team 26 will have to find an independent machinist to have our cold plate ready in time for us to assemble the entire system together.
