Week 9 (03-21-18): Creating The Turn Sections & Cleaning Up The Concrete

This is the week before Spring Break and the team is motivated on gaining some headway with this project. The last couple of weeks we have mainly been doing preparation work to get some of the components of the track completed. This week, however, Kevin worked hard to complete the curve sections of the track with his bender mechanism. The completed part can be seen in the figure below:

Based on last week's work, the team poured concrete into the concrete molds, found in the image below. This week, the team took apart the molds and cleaned up the concrete that sits on top of the leveling mechanism of the supports. Since some of the molds allowed minimal concrete to spill over, the team needed to break the stray hardened concrete. The finished leveling system is shown below:

The team has spent a lot of time in the shop and hopefully, we are able to use this break to regain energy in order to finish strong.

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!
