For this week, I continued machining and fabricating parts for the brake assembly, completing every piece aside from the gearbox. I currently, and temporarily, mounted my pieces to the bogies yesterday to test the fit, which seemed to work well. Then I will finish the assembly at a later date, once I get the correct bolts for the job.

This week was mainly spent in the machine shop. Most of the parts for our team have been cut to shape and need to have holes drill through them. I am hoping by the end of this week, or by next week, we could have the mounts for the propulsion motor finished, as well as the braking mechanism. The gearbox for the brake will take a little longer due to the complex shape, but it should not take much longer than the rest of the machine. Otherwise, we need to figure out a way to buy our motors for propulsion, and we are coming up with ideas now.

Within the past two week, the brake design has been completed and fabrication has begun. I went ahead and bought the extra metal that I needed for the design, finidng appropriate stock material. Then from there, started to cut the stock to length and prep it for the mill, and cnc mill. Additionally, I preformed some FEA on the parts that have been design to make sure that the brakets for the motor would be able to hold up to the forces produced by the motor as well as the weight of the motor itself.

This week I spent time turning shafts on the lathe to press fit gear onto for a gear box. It took some time to get the proper shape. Also there was a lot of time spent redesigning the brake, sizing springs and some wire to make the thing work. I believe the redesign will be fore effective than the caliper and master cylinder system that I originally though of.

This week was mostly dedicated to development of the brake and its design in solidworks. Mostly working on the placement and the movement of the brake actuator. As well as a bit of research as to where I could pick up a master cylinder and was planning to visit a junkyard today in order to scrap a master cylinder from an available car.

Hey, I haven't done much this week due to some complications on my computer, I was attempting to reinstall solidworks on my computer and am having a bit of difficulty with the licensing, therefore I started to redesign the brake within creo just so I could keep moving forward with the design of the brake.
