 I have found a welding shop that gave a cheaper quote  ($250) at Quiet Horsepower compared to the initial quote by Nam's Welding. Additionally, he plans to use TIG welding compared to MIG welding used previously. TIG welding allows for more precise and clean welding beads He has already tack welded half my parts and  the plan is to finish the rest of the welding on Friday. I have provided the images below. Furthermore, I aim to be test fitting my parts to the slave bogie.

Articulation
We finally got parts out of the waterjet we are still waiting on the CNC to finish the parts 
There are some components that need to be welded we are waiting on a quote from quiet horse to see how much it will be
Here is a picture of what is done so far

E-Brake

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.

Week 11

Week 11, For this week the team continued to work on our individual components Articulation: currently redesigning thrust bearing carriage, need to consider there being an axle that connects both wheels together. currently designing pins that will lock in place for the steering rack, Guide Arm: currently working on improving on the design for the spring holder and wheel holder the Safety factor is really high attempting to decrease material and make design changes to improve design and optimize for safety of factor above 2, but not extremely high. images of the components are provided that show area where material can be removed. furthermore, the prototype should a concern a different loading concern when it comes off of switching tracks, the force will not all be perpendicular to the track, so additionally FEA was done with different loading conditions. minimum Factor of safety = 27 goal for next week start report Redesign the "arm" for the

Week 10

Week 10 this week the team worked on finishing up solid work models and conducted FEA on most of them Through rapid prototyping we were ale to see that our designs had a few problems that needed to get fixed before the final product. Articulation The problem with articulation structure where it would fail when loaded with 2500lb was fixed by adding a small section that helped reduced the moment arm caused by the bearing carriage. Shown in next figure.  The following figure shows the redesigned part. This new design greatly reduces the moment arm allowing the structure to carry more weight. This design has a factor of safety of 8.86 this means there is alot we can do to improve the design and reduce its weight from current 14 pounds. Since the bogie will not be using an axle we had to think of a new way to mount wheel housing to the new articulation system for now we designed this component which works as a carriage for the thrust bearing and also has mounting holes

Week 13

There is less than one month before this semester ends and we are starting to shift our focus on to our project report. We feel that we have enough information to discuss our progress. We have made significant progress with our designs and will continue to tweak and improve details. We have ran FEA calculations and have made prototypes to test out our designs. With finals coming in a few weeks, we would like to make significant progress to our report each week and hopefully have our reports completed before the week of December 10th. Guide Arm I have added mounting points to the guide arm for the drive bogie, and have tested that it fits the drive bogie. Now the interaction team needs to add mounting points to the drive bogie. Last, there was also focus on completing the last individual writing assignment. The goal is to determine mounting points for the slave bogie next. FEA was also completed on the guide arm with these new mounting points, and two different loading scenarios wer
