This week, our team continued to practice our welding on spare metal in the shop. We all tried welding the steel flat bar to the square tubing, but we all came into problems of overheating the thinner square tube, causing the walls to melt. After some time, Bryan had the most success controlling the heat, so we decided to designate him as the team welder.
While Bryan worked on the welding all of the configuration in Figure 1, Kevin and I prepared more square tubing for the top section of the support, seen in Figure 2. Kevin was also able to print the third rail support component of the switch section, seen in Figure 3, at home.
During this week, as well as previous weeks, our team has come in on our off days to work on the project. With so many parts to manufacture for this project, coming in once a week will not suffice.
