Step 7Error Dynamic
Error Dynamic
For my projects, I use the term Error Dynamic. It's basically a way of designing something for my skills at th.
When designing rockets you probably want some sort of aerodynamic design to your rocket. Myself, I prefer using "Error Dynamic" design meaning to design something knowing that the lines might not be totally accurate and measurements might vary a bit.
Bike spokes are great for error dynamic design, I wanted my spokes to be 6" long. Since cutting them all perfectly at 6" was sort of out out the question I was pleased to find out I had about a quarter of an inch adjustment thread with the spoke.
The sides to hold the spokes are a set of holes drilled into some lattice. To make sure the holes lined up, I stacked the 4 holding blocks and drilled them 2 at a time. I did some rough measuring although the drill kind of did it's own thing. See the photos for notes on the holding blocks. I could have probably just put the holes into the side of the endless sketchbook but, that would mean that my spokes would all have to be have cut with only about 1/8 of variance. I By adding the blocks, I've allowed myself to have almost 3/4 of an inch of variance.
It took me a while to find the perfect thing to spin around the spokes, I knew that the paper wrapping around the spokes would certainly cause too much friction not to mention that the metal would tarnish the paper.
I tried using small tubing an putting it on the spokes, this was only partially successful. I was relieved when I went into SCRAP one day and my solution was right in front of me. 6000 drill bit rings for $4, perfect. These help the paper easily turn, reducing friction and helping this prototype along.
Threading them on the spokes took some time but, it was well worth it. If you would also use drill bit rings, you could try to purchase them through SCRAP or write me and I'll send you a bunch. There are several alternatives that you could use although I'm not sure how well they will work as I only tried tubing and then found my drill bit rings. I was thinking that it would be pretty easy to use beads and put them on the spokes. I was about to take apart an old printer as I'm sure there are some good round spiny things inside of one of those. If you would really like you could probably just make some bead like things out of Fimo or Sculpy. It is important though to get rid of the friction.
The spokes will stay pretty rigid although putting side that caps the spoke on is kind of frustrating and annoying as they don't perfectly line up.
