Week1 Narrative
In week one what i did was research Google to get some ideas how the steam engine works. Also searching for what materials are needed. After doing this thing, I drew the diagram of our steam engine because i tried to get know how its materials are connected each other and how it does work. T also tried to remember the mane of all materials use for being familiar with them and help when doing actual work. I also drew every single piece of the material such as exhaust steam, piston, cylinder, valve rod and other materials why i did these thing is that i don't really know about this kind of stuffs so that i expect drawing picture will help me in doing my project. I actually more focused on the piston part so i tried to be familiar with the following diagram of the piston part which can be seen in the following. http://upload.wikimedia.org/wikipedia/commons/c/c3/Steam_engine_(PSF).png

Week2 Narrative
In week two, what we did was decided to design the steam engine piston and cylinder in solid edge. Why we decided to design it in solid edge is because we thought that it's can be printed in the 3D printer. I basically designed the cylinder and the piston in the solid edge. Mainly what i focused on it is the hole on the cylinder where the piston road goes through We decided that every single person in our group much as we can and so we will take the best one, therefore,I tried to make a hole in as much as i can however, i could not really make it. I also looked the you tube how its hole is made not only that i asked some friends how its hole is made.Even though i could n't success to design, i still researched about we are going to print it in our 3D printer. I tried to make that a hole so much time,unfortunately it didn't work out so that i decided to come class earlier then worked together with team because i thought that if we worked together,we can combine our ideas and it may work out.One of my problem was that i did't use the solid edge monitor before so that it took me along time doing things.

Week3 Narrative
In week three, we kept figuring out how the hole makes. I finally could make that hole after spending couple days. how i could finally make it is by helping me worked together with team in class.However,there was still some issues doing two little holes where the air pressure goes. I mostly done my previews problem which is big hole the final week. I basically designed the cylinder box which is 10 inches long and 5.05 inches high. As i already mention, we have to have the hole where the piston road goes therefore, i designed the hole about 9 inches long. After fishing these things, there wasn't pretty nothing i could do because there was problem with doing the little small two holes and I couldn't go any father. After struggling with that,We just decided to more focusing on the piston making by PVC. I actually didn't make the PVC piston,However, i tried to get the ideas to promote our PVC piston work. After starting to design the PVC piston, i did some research Google and you tube. I basically tried to find the picture of the PVC piston for getting some ideas.

Week4 Narrative
The next step to do while the rest of the group was working on the 3D design of the steam engine was for me to make a physical representation of a double acting piston steam engine piston. It was decided to make the piston cylinder out of PVC because of its pressure rating and its price. It was decided to use a 20" length of 2" PVC pipe so there would be room for more error than there would on something smaller. Next a 20" piece of 1/2" PVC was cut to make the piston arm and to that was added a 1/2"x 1" bushing, a 1"x 1-1/4" bushing, and a 1-1/4" cap to make the piston head. Now wrap tape around the piston head until it just fits inside the 2" PVC pipe. Next, cut a 1/2" hole in the center of a 2" cap to the piston arm can just fit though it. Put the piston arm though the cap and connect it to the 2" pipe so that the piston head is inside of the Piston cylinder. Now put another 2" cap on the other side. The Piston Cylinder is now ready for the airports and to be connect to the pressure switching cylinder. The next step was to drill 2 1/4" holes on the 2" PVC cylinder 2-1/2" from each end of the cylinder for airports. The ports are positioned 2-1/2" from each side to avoid the piston head from bottoming out. Now that the holes are drilled screw in 2 1/4" male to male couplings into the holes and to them screw on 1" lengths of 1/2" CPVC pipe. Next, connect 2 3/4"x 1/2"x 3/4" CPVC T's to the 1/2" CPVC airports. Then measure to distance between the two T's and and cut a piece of 3/4" CPVC pipe to an longer than that. (So that the 3/4" pipe could fit inside of the T's. Than drill a 1/4" hole in the center of the 3/4" pipe so an air inlet valve could be connected.
