Good progress! I think mono-metals are a lot easier to design, especially for a first one, which is why I’m focusing my time on that. I see you also rounded off the edge of the response, which is a good catch.
The outer edge of the rim looks sorta sharp - what’s the arc radius there?
For anyone else reading, here are some good resources to get started, a youtube tutorial series by Zach Lerner:
- Lesson 1: The Guts
- Lesson 1a: Mass Moment of Inertia
- Lesson 2: Design for Performance
- Lesson 3: Limit State Design (Machinability)
Here are some general rules for wall thickness that I got from Jordan, the owner of Smashing Yoyo Company:
- 6al-4v grade titanium is 0.5mm
- 7075 is 1.0mm
- 7068 is like, 0.8 mm
- 6061 is 1.5 mm
He tends to add 25% unless he’s going for something extreme - too thin and it can warp during machining. Also, don’t create a thick part surrounded by two thin parts.
