During this week, the small scale teams were able to present their work thus far. The presentations were split up into three parts, which were the introduction, the model design, and the overall progress (Gantt) chart that we've made out for ourselves. During the presentation, we gathered a few ideas an worked to incorporate those ideas into our design. For example, Dan thought about incorporating a leveling system that that incorporates screwing into the concrete and allowing us to create a leveling system with three points on a plane that will level the entire system. Hopefully we are able to work on these designs moving forward and incorporate them when we start rapid prototyping.
On Monday, the team met up and needed to address some of the issues that we had with the welder. Kevin was in constant communication with administration and Dan (from full-scale bogey) to ensure we were taking the correct course of action. Kevin and I took a trip to Praxair to retrieve a new tank of Argon for the remaining welds. After coming back and setting up the welder, I started and finished the welds necessary for the support structures. I encountered some issues during this process as I never found the correct way to properly weld these two components together due to the differences in thickness of the square tubing and the sheet metal. If I utilize too high of a current, the sheet metal would have a hole burnt through. However, if the current was too low, there would be no penetration of the square tubing. Even after completing 80 welds, this process was not mastered and still need to be cleaned up through other methods that will be looked into.
