Week 3/7

Finally got the O.K. to start order parts. We are going to use the extra sheet metal with a thickness of about 3mm as a cut out for the main assembly. Here is a drawing of how we will use most of the sheet metal. The sheet metal has a surface area of 48 inches by 68 Inches.

Week 2/28 and 3/1

This was part of the presentation week to show our current progress and as well as all the other teams. It is shown on the FULL SIZE BOGIE TEAM blog.

Week 2/21

I came across an idea of implementing the linear actuator on the switch. Translating the linear motion to a circular motion is shown below.

This is the cad of a linear actuator that i will be using

Week 2/14

Upon looking at the switching mechanism of the bogie, i thought about utilizing a motor i had already had. The actuator i have is a 12v door actuator that is using in car door locks. So instead of purchasing a new motor to turn the switching mechanism, i want to implement using linear 12v door actuators. They have not polarity therefore with an opposite charge it can go the opposite direction. Initially, the idea was to use another pulley and belt method to turn the wheels.

Week 2/8

The team has decided to model the prototype with plywood. The plywood we will use is 1/4 in birch wood. Due to lowering budget costs, I've search for the most affordable yet accessible plywood in the area in which I've found 1/4 x 4 ft x 8 ft at Home Depot for approximately $28. Will visit home depot to check on the quality of wood.

Week 15

Presentation Day

Unfortunately, I was hungry and lacked sleep so i was unable to perform well in the presentation. 

Other than that, as a group we are to write the full report of our findings as the bogie team due at the end of the semester.

Shown on the team blog: https://fullscalebogieteam-2017-2018.blogspot.com

Our group is now going to plan for next semester and figure the days that we are able to meet up. Starting on fabrication of the actual bogie will surely be a difficult task. The main things that hold us back - and the other teams - is funding. Although, i do believe our team will be able to succeed. Over the winter break, i will certainly continue to research programs that support senior projects or simply ask around from vendors. Atleast discounted parts will help.

Week 14

Was tasked with working on bill of materials with generic prices of parts we needed.
The total came out to $1789 per bogie in which our prime design requires 3 total bogies.
For the whole design, its should reach around ~$4500 given that the bill of materials included over quantity for a single bogie. One part that i will include in pricing are welding materials.
