During this week, I hunkered down and completed some of the welding tasks that needed to be done on the hot rolled steel flat bar and the square tubing. In addition to this, Kevin started mixing concrete for us to test the welded pieces on. We started pouring, mixing, packing, and flattening three of the four compelted bases with flat bar and square tubing. While the concrete was curing, I finished up all 80+ welds that needed to be completed for the base. By getting this much experience and repetition in, I was able to get a quick hang of creating a proper weld. and learned to adjust the current levels of the TIG welder in order to control the amperage of the arc and not melt holes through the thin square tubing. We came across another setback and forgot to weld the nuts on the hot rolled steel flat bar, so it looks like 80+ more welds to compelte. I think I should be good and will get this work done by next week.
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....
