During this week, the main focus for the track team was to hammer out the last design decisions and tweak some of the decisions made from last week's progress. The main issues that we really have to address now is the support design since the model needs to be robust and can work under different scenarios. When bringing the whole model to an event such as Maker Faire, the ground may not be level and we need to address that, as well as incorporating a way to fasten the design onto the track. Moving forward, I'll work on the CAD this weekend and gather some ideas, that way we can incorporate them into the presentation.
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....
