Write problem/project Goal
Over the last 4 weeks, we got a design mostly nailed down and parts were cut. The next 4 weeks are about crank shaft design, assembly of the Beest and powering it.

My First Task
Work on plan for crank.

Summary of actual work over first weekend
Stuck to plan.

Week1 Narrative
Talked with some co-workers and got input. They suggested a circle instead of an arm for balance. I think this is a good idea. Also suggested using a secondary crank without cams to turn the first one. This would help with torque if it had bands to each cam, individually.

My Second Task
I am going to take home some parts and build one more leg assembly. This time I am going to take pictures and make a tutorial.

Summary of actual work over second weekend
Stuck to the plan mostly. I did get a little off target with some experimentation on the crank shaft.

Week2 Narrative
I started on Friday night with taking pictures of the parts. I had built one leg set before, but the process was not recorded. This time, I followed the same method, but took careful note of each step in the process. With this second build, I left the crank portion off. The reason being that this leg set is for assembly on the whole Beest itself, not a demonstrative prototype.

I did not bring enough parts home to make more than one, so I put the one I made before together with the new one using pieces of coat hanger for the body bars and another bent coat hanger as a make-shift crankshaft. It did not move very smoothly due to the inferiority of the crankshaft material (I didn't expect it to work at all so I was semi-pleased). However, you can see the basic idea of the Beest's movement in this short video of my 2 leg sets at work.

After making that video, I got to work on making a tutorial on How to Assemble a StrandBeest Leg Set. This is not a tutorial on building an entire strandBeest, but how to build the legs so that they are ready to put together with the other soon to be built leg sets and Crank Shaft. I uploaded the photos I took of the parts and of the various stages of the build and incorporated them into the tutorial as well as a few video links. Link below

Lastly, I did a quick CAD drawing of a circle with some drill points on it, that we could cut out on the CNC router if we could get another piece of wood. These would be useful for the crankshaft.
