After doing some research I recently discovered that AutoDesk offers their Fusion 360 CAD program for free to hobbyists. So I have decided to switch to Fusion 360 from SolidWorks in the hopes that in doing so other people can more easily recreate, modify, or otherwise explore 3D models that get made in The Workshop. If you are interested in downloading and getting started follow this guide:
Our old Powerwheels chassis has taken a beating over the past two years now. With that being said, the team decided to create a new chassis and retire the old one. The layout of the new frame is a rather simple design, yet it is structurally sound enough to get the job done. The rear end of the old frame will still be used in our newer since it seemed to be the only part of the old chassis that was not bent or structurally defected.
Ever since attending the Mini-Maker Faire in Miami this year I have been thoroughly excited for Orlando’s event. There were so many cool projects and people this year and it was awesome being able to see everything that was on display. There were three things that really stood out as I browsed the Faire. Outside of the Workshop I am the president of a robotics club at a local university, and so it should come as no surprise that my favorite things to check out were all the amazing robotics being shown. From FTC builds to Battle Bots, Astro droids to Repair Droids there were all amazing. Two robots in particular that stood out to me were the Renaissance Robotics FTC build and steampunk R2 Droid.
I have been extremely busy in the workshop recently and trying to make more progress on the turbine has slowed down a bit since most of the turbine unit is disassembled. The last part of disassembly of the turbine deals mainly with the CHRA and removing the journal bearings completely. Tools necessary for the task:
1. Small snap ring pliers
1. Small snap ring pliers
The initial teardown of the turbine started with the larger and more basic components of the unit such as the housings, drain pipe, and other various components. It was then that I was left with just the CHRA and its internal components. So now I began the teardown of the internal parts of the turbo.
In the perfect physical world, there would be no gravity or no coefficient of friction. As we all know that is completely unreal. With the idea of gravity in mind, it would be in everyone’s best interest to try and reduce the coefficient of friction as much as possible. Reducing the coefficient of friction in general helps improve efficiency and performance of almost anything moving (i.e.: bearings, lubrication). Now you are probably asking yourself why should someone or anyone know this vague information. The answer is that this same basic principle applies to your daily activities whether you notice it or not. The easiest example of this is the car you use to commute to and from point A&B. To demonstrate this theory of reduction the coefficient of friction, I will be inserting new ball bearings into a 30-year-old turbo charger that is used on gasoline and diesel engines.
