This week has been a week of progress, as components are completed, hardware is acquired, and inspiration is gained.
Last night I saw the movie The Martian. Although it’s kind of riding the wave of space movies like Gravity and Interstellar, it’s still a welcome addition to the trend. In the movie, Matt Damon gets stranded on Mars after an emergency evacuation from a storm (apparently there are storms on Mars) when flying debris separated him from his crew. The movie is jam packed with Matt Damon doing almost believable makeshift science to keep himself alive, as well as a tremendous team-driven effort on Earth to get the astronaut back home. I was inspired by this resourcefulness, the illustrated power of engineering and science, the pursuit of the unknown, and the feeling you get when your dreams come to fruition.
For so long the Grazer has been a figment of my imagination, at most some sad little pieces of aluminum. Finally, however, the true project is coming to life. Whenever I really start to get underway with a project, wether it be a treehouse or a strandbeest, I get a feeling like I’m actually doing something worthwhile. With this comes motivation, and more excitement to get back into the shop and continue working. Moral is high.
This week, I focussed again on figuring out the aluminum triangles. I ended up modeling the first one in Fusion 360, using the Sketch function instead of 3D parts. This kept everything in two dimensions and simplified the whole design process, which was still actually pretty complicated.
I plan on securing the corners with plates and rivets (above), as well drilling screws through the corner into an end of aluminum tube jammed with Delrin (a type of strong machinable plastic polymer). Picture on that pending. The only reason I haven’t yet riveted the rivets and screwed the screws is because I don’t have the right screws, so it’s hard to screw a screw that’s not there.
I also got some cotter pins for my joint axes, and drilled holes to fit into all the joint components. They look like this:
Hopefully by tomorrow the triangle will be put together.
