This week I was able to completely finish my system. I was able to mount it on a platform and start to test it. I am very happy to say that I am finished testing my design and it performs exactly as I had expected to. I probably will not be able to test it on the track since it is not ready, but I am confident that it will perform to its specifications. Additionally, I made a slider mechanism which allows adjustment of the braking system. As of now, the braking system is ready to mount on the slave bogie.

This week I was able to get all of my parts welded from Huffman's Welding in Newark, CA. The parts came out excellent and the next step is to be to assemble everything and begin testing of the system. The picture below shows the welded parts.

The emergency braking is almost ready for testing. The manufacturing is almost complete with an exception of the welding work. The parts have been sent out for welding and I will get them back on April 29th. After the parts are put together, I would like to start testing to ensure that everything is in working order.

This week I was able to make good progress on the braking system. I spent about 20 hours in the machine shop making my design. Unfortunately, I made a mistake on two parts so I had to start over. Parts finished are shown and listed below. I am currently prepping to have my design welded as well. -8 side pieces. -2 Mounting brackets -2 Bottom sliders -1 Top slider -1 Shaft -1 Top slider -1 Electromagnet holder Needed: -1 Top slider -1 Shaft -1 Electromagnet holder -Welding

This week the team prepared for and delivered our second presentation. I was able to get full access to the mill and lathe in the maker space. Additionally, I was able to get access to E123 shop. This will greatly accelerate the production of my design as I am manufacturing myself. I did not make any progress this week in production since I did not have full access to the lathe in the mill until Wednesday April 10. I was able to purchase the hardware needed for my design. Next week I hope to make good progress in production.

This week during spring break, I went to the makerspace area to start fabrication on my design. I had a slow start but I feel confident that I will be able to make my parts. I started to machine the bottom slider and top piece of my design using as lath and mill. I look forward to going to maker-space this whole week but I have limited access because there always need to be someone supervising.
