Give instructor top 3 project choice list
We were allowed to continue our work on the Rubber Band Gun project.

Write problem statement
We need to perfect the firing mechanism of the gun. If that can be done, assembling the gun will not be an issue.

Assign Task1
We are each supposed to do some research and decide what design we will use.

Compare actual work done to Task1
The same, no differences to rationalize.

Week1 Narrative
During this week, I made numerous sketches that can be found in my Engineering Notebook. These sketches are on various things like firing mechanisms, free wheeled designs, cases, and barrels.

Week1 Peer Review
done (I commented on my team mates' pages)

Assign Task2
Do further research and designing.

Compare actual work done to Task2
I did what was assigned, no differences to rationalize.

Week2 Narrative
During this section, I made numerous sketches that can be found in my Engineering Notebook. These sketches are on various things like firing mechanisms, free wheeled designs, cases, and barrels. I also, compared materials for the tube for the barrel.

Assign Task3
Research designs for the firing mechanism and be able to make an informed opinion about what kind is best.

Compare actual work done to Task3
I researched designs for firing mechanisms and more. I sketched up more designs on my own, and I did more research on the details of the firing mechanisms of other types of rubber band guns.

Week3 Narrative
I researched designs for rubber band guns. Found mostly designs, tutorials, and examples for single shot guns. Some were "bolt-action" and others were regular single shot. I found one design that was a machine gun, but was not a gattling gun. I did extensive research on this gun which used a "free wheel" design to fire multiple shots quickly without reloading after each.

Week3 Peer Review
done

Assign Task4
Draw multiple designs and figure out what I think will work best for the gun. This will include researching and drawing and thinking critically about the firing mechanism.

Compare actual work done to Task4
I made numerous drawings of the mechanisms involved in the rubber band gun. Firing mechanism sketches are on pages 39, 45, and 47 in my Engineering Notebook. Trigger/ releasing mechanism sketches are on pages 39, 41, and 45 in my Engineering Notebook. Firing mechanism casing sketches are on pages 49 and 53 in my Engineering Notebook. Full assemble sketches are on pages 41, 45, and 47 in my Engineering Notebook. These sketches are made with enough detail to really start to put the whole project together. (This is exactly what I said I would do, so there are no differences to rationalize between what I decided to do, and what I actually did.)

Week4 Narrative
To serve as something to base my sketches off of, I had to use the research that I have done in the previous weeks and more. I have really had to focus on the details of the mechanics of these rubber band guns. I will post links to some of the most inspirational parts of my research. Some links will be to videos, and others will be to pictures. Also, I will copy information from other sources and paste it below to show some other ideas. I will give a brief title and/or description for each line item.

This is what the main project is based on. This is probably the best video of it because it shows it in use and up close enough to see details.

Rubber Band Gatling Gun

This is what the last session of this project was based on. We tried to get this idea to work, but it never came about. This does evidence that our ideas would have worked eventually. Also, there are a few details gleaned from this (and that previous session) carried over to this session.

Original Idea

This is an example of a machine gun that is not a gatling gun (gatling guns need to have a spinning barrel).

Machine Gun

This is an example of a locking mechanism on a free wheel driven rubber band gun. We are using this design because the rubber band is the force that drives the free wheel forward when the locking mechanism is not holding it in place (in other words, when it is free).

Free Wheel Principle

Week4 Peer Review
done (I peer reviewed my team mates' pages) Mderrick has shown many designs and helped develop the firing chamber used with the 10-count trigger set. These designs are coming to fruition with the wood I've purchased. He has truly helped this project progress from the spool-style to the trigger-style gatling rubber band gun. We need to see more actual development in the manufacturing of a rubber band gun though. Also, he has not updated his wikiversity project page in some time. CFurby 05:07, 4 December 2011 (UTC)
