Week 8 (03-14-18): Welding the Nuts on the bases & Pouring the Concrete into the Molds

During this week, the team met up a total of 3 times within the week, including the time spent on Wednesday. Throughout the week, I worked on what needed to be finished with the welding for the nuts and hot rolled steel flat bar. With 80+ welds to complete, I was able to work through the 17 bases that we needed welded through. Since the welds were completed, It was time to pour the remaining 17 bases in order to test them out and see how they perform under the given load and unevenness of the ground. We poured, mixed, stirred, condensed, and flattedned the concrete to fit the necessary molds. All we have to do is wait for next week in order to see how the concrete molds formed. I hope it is the same, if not better than the last three that we tested.

Week 12 (04-18-18): Welding For Last Support Components

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.

Week 13 (04-25-18): Cleaning up Welded Track Attachments

This week, I focused my efforts on cleaning up some of the welded sections that I worked on last week. Within the square tubing, there is a slight rise that follows along the length of the tubing. This makes it impossible for these parts to slide into the support sleeves that we have already made. In order to finish up these components, I filed them down with a combination of using a Dremel tool with a diamond bit tip and Spartan Superway's file. The first image shows the excess metal that protrudes out of the inside of the square tubing. The next image shows that same protrusion grinded down with the use of the Dremel tool and shop file.

Week 15 (05-09-18): Final Presentation

This week, we gathered at the Student Union to finish up the last presentation of the semester. We met up several times to ensure that our last presentation had the proper flow and clarity so that anyone who hasn't encountered Spartan Superway will know the scope of our project. Most of the time was spent ensuring that all of the work we did this semester was covered comprehensively. We even included a master slide system and an appendix section for all of the miscellaneous FEA Analysis and manufacturing questions that members of the crowd might ask. The last presentation of the Spartan Superway Track Design and Manufacturing team is shown below: Now it's time to get ready for Maker Faire!
