Week 6 (02-28-18): Welding, Welding, Welding

During the course of this week, the presentations were proceeding and I also gave my shot at welding to help the team make the bases by welding the hot rolled steel flat bar with the steel square tubing. After the material was previously prepped, the team came across some issues due to the thinness of the steel square tubing. We ended up burning a hole through with the first try of the hot rolled steel flat bar, which is bad since we are planning on filling the bases with concrete so any holes would allow the concrete to seep in, which is undesirable. In order to get this task completed, I ended up taking charge and focusing on manning the welder while the other team members were left in charge to complete some of the aluminum manufacturing. I ended up completing about 20 welds with the square tubing and hot rolled steel flat bar, which resulted in 4 completed pieces. I feel like we are starting to hit our stride and hopefully with this kind of work ethic, we are able to stay ahead of our planned schedule, so we have more room for troubleshooting.

Week 14 (05-02-18): Finishing up the Supports & Putting the Track Together

Last week, I ground down the welded support parts that attach to the track. I finished 20 of these parts and it required a lot of patience since grinding down steel requires some time. I even had a collet for the Dremel tool break on me since the diamond tip Dremel-bit pushed the collet to open up throughout the duration of the grinding process. By trying to close up the collet to secure the bit, one of the collet's prongs broke. After these parts were completed, I started drilling holes into them to ensure that they would fit into the whole track assembly smoothly. I used the drill press and some of the brackets that Kevin finished printing. The end result of these components looks like the following image: After the support structures were put together, we assembled the track fully for the first time. Although it was a small assembly that reduced the length of the track, due to removing several straights, it allowed for the other subteams to test the bogey and controls....

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!

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.
