Write problem/project Goal
My project is to build a rubberband gun out of wood.

My First Task
What I am going to do is decide which type I want to choose from since the designs are endless. As well as start to buy my wood and make my measurements.

Summary of actual work over first weekend
What I did over the weekend was actually very much like I said I would do.

Week1 Narrative
Over the past weekend each one of my team members decided that we should each build our own rubberband guns. The type that I decided that I wanted to build was a 10 rounds Rubber Band Hand Gun, P201 Ai-Oh (1/2). The tutorial on how to make it is here Tutorial.

Materials:
 * A 48x3.5 inch piece of wood
 * A ruler
 * Pencil
 * A wood saw(or anything else that will help you cut wood)

So what I ended up doing was heading over to the Home Depot over the past weekend to get the perfect wood size that I would need. I ended up getting a long piece of wood that was 48x3.5 inches. Like the picture below illustrates.

Then from the tutorial I started to make my measurements. The first thing I needed to measure out was the Barrel. I measured out 345mm (or 34.5cm) and 15mm(1.5cm) in width. Next I measured out the 10 holding spaces for the rubberband that were each 10mm(1cm) apart with a depth of 5mm. This was kind of difficult because I had to mark 200mm from the end and then work back words 10mm each space. This is what it looked like when I was done measuring it out. Once you've done this you are done with the barrel.

Next would be measuring out the sliding bolt. The sliding bolt is 200mm by 15mm in width. That was the first step is just marking off the space you would need. Now just like the first one where I had to measure out the 10 holding spaces I will have to do something very similar but for 10 notches spaced out 10mm from each other with a depth of 4-5mm. However for this one you measure out 107mm from the end back to the front and start off right there your 10mm marks. Unlike the barrel where you measured back and started from the end. A picture of how this will look like is below.

After this it's just measuring out your block of pieces 1-6. Each of these pieces of wood are 15mm by width but vary by length. P1 and P2 are 60mm, P3 and P4 are 40mm, and P5 and 6 are 20mm.

The last two parts are very similar to the last procedure. We are just building parts P7-12 and the trigger tool. For P7-9 they are all in a width of 9mm but length varies. P7 is 55mm, P8 is 15mm, and P9 is 185mm. For P10-12 they have a width of 9. P11 has length of 25 while P10 and 12 have a common length of 30mm. Lastly the trigger bar has a dimension of 177x9 inches. The picture below illustrates this.

Sadly I didn't have anything to cut this with so now that I have all my essential parts measured out and ready to go I will go in the engineering room tomorrow in order to complete that task. Overall I have everything I need for this project. The pictures all combined with the parts at the end will look like the picture above.

My Second Task
My second task will be to cut out all my pieces and start assembling them together.

Summary of actual work over second weekend
What I did wasn't very different than what I planned.

Week2 Narrative
What I did was cut all of my pieces that I need for example my trigger bar, my barrel, the sliding bolt, and P1-12. What I used to cut this was a jewelers saw which was very thin and precise for my cutting. I also used a table saw to cut the main big pieces and the jewelers to cut the individual small pieces.

First I started off with the table saw to cut the barrel, the sliding bolt, and the three pieces p1-6, then p7-p9, and finally the bar with the trigger tool and p10-12.

After this all I had to do was use the jewelers saw since the table saw was too thick to cut such thin and precises pieces. First I cut up the individual pieces of p1-p12 and the trigger bar. However it didn't come out as smooth as I wanted it. What I need to do is just sand it down a little bit to make the surface smooth and precise.

The next two parts were the most difficult just because cutting out the 1inch holding spaces was so complicated. For the barrel I accidentally over cut it so I had to remeasure it and cut it out again. This time I didn't cut out the holding spaces just because I want to find something in class that will be more precise for me to cut it out.

I also went to home depot and got wood plates that were 5mm thick.

My Third task
During the third week I will put all the pieces together doing all the gluing, drilling, and assembling.

Summary of actual work over third weekend
What I did over the past week isn't very different from what I said. I started to put all the parts together.

Week3 Narrative
Over the past weekend I headed over to the home depot to purchase a few items that I needed to complete my cut outs. The first thing I got was a 2 foot 5mm thick wood plate, and a 2 foot 9mm wood plate, and wood glue since I knew I would need it for later.

The first thing I did was the left frame cut out. This was a bit difficult since the cut out of it was kind of complicated. First I measured out 322mm in length and 58mm in width, and traced this out. Then what I decided to do was measure out the top first and then work on the bottom. For the top left I measured 22mm and marked it, from that point I measured out 25mm downward and marked it. From this I measured 150mm across and then 17mm going up. Finally the rest was just 150mm across from that point. Now to work on the bottom half of the wood plate all I did was measure out 190mm across and then 28mm going up and marked that point. Then I measured 86mm across from that point and 10mm down. From this trace I took my piece outside to cut it out. I used wood clamps to hold it in place while I used a wood cutter to cut the plate precise. After I was done cutting I used a sanding sponge to get rid of the ridged edges and make it smooth. Now since I needed both a left and right what I did was just tracing the one I already cut out and cutting it and sanding it down so that they can be exactly equal and I wouldn't run into any problems later.

Then the next piece I did was the left and right grips. For this I just measured out 35mm on the top and 100mm on the left side. Then the length of the bottom piece was 45mm so it is a angled piece. Then I connected the end of 35mm and 45mm and I got my piece. I then took this to the wood cutter and cut it out and sanded it down as well. I used this piece to trace out my right grip and did the exact same thing.

Last but not least I made my ratchet piece which was very difficult with all the measurements and angles, a picture of how it came out is down below.

Now that I had all my pieces cut and sanded out all I had left was just start the building process. The first step was taking my P1 and drilling a hole of 2-3mm on the point where it measured out 23x5 from the right and marking that piece as the picture shows. Then on that mark I drilled a small hole and did the same for P2.

Next I took my P5 and P6 and glued them together with the wood glue that I purchased from home depot. Next I took the end of P5 and glued it to the trigger bar. I also glued P1 and P8 together and glued the end of P1 to the right end of the trigger bar 10mm away. Next I glued P2 on the opposite side of the trigger bar parallel to P1. This is what I did for this past week and overall I don't have much more to go.

My Fourth task
For my last and final week since there isn't much to do but just do gluing and more drilling I will finish the gun.

Summary of actual work over fourth weekend
What I did over the weekend is very similar to what I said I would do I did all the drilling, cutting and assembling of other parts.

Week4 Narrative
From the point that I left off last week what I continued to do this week was just more assembling. The first thing I did was insert my ratchet box in between pieces P1 and P2 and drilled a whole in them to connect it. Then I started to work with the barrel and the frame L. I took the barrel and layed in on top of the frame and measured 43mm and then drilled a hole there to later connect my pieces. After I drilled my holes I took a small 2-3mm screw and screwed it in. I then proceeded to my P7 and P9 and glued them on the frame L. Then like in the picture below shows I took my p3 and p4 and glued them at the end of frame L and the trigger bar 12mm away from it. Next was gluing in my grip l to the frame. This grip went on the back side of my gun and had p12 glued to the bottom of it so it could later glue grip R to it. Now inserting the sliding bar was the difficult part. The sliding bolt went in between my barrel and the frame. It had to be adjusted so that the ratchet went in between the first notch and it was 2mm away. Once I finally got this I glued it down so it could stay in place. However my sliding bolt wasn't exactly where it had to be which is where my problem came in. There wasn't the exact space that I needed for the ratchet to be 2mm away from the first notch and this potentially threw off my whole project. However I did get to build the whole gun but because of this essential piece it wouldn't release the rubberbands correctly.
