I have begun searching the internet for pieces that exactly fit the concepts I have devised. I hope to find the pieces that will assemble into my nozzle apparatus by (shortened) week's end.
12/23
All of the pieces the nozzle apparatus will be comprised of have been found. Unfortunately, certain dimensions are missing from their online descriptions. Over the break I will have to find out what those missing variables are.

Weekly Update 12/15-12/17
12/15
I have been in the process of completing my materials list and plan of procedure. I have also been working on my drawings. I will attempt to get as far as possible by the end of the week.

I have comprised a rough outline of my materials list and plan of procedure, and have completed all of my drawings, save the exploded view.

Weekly Update 12/8-12/11
12/8
Today, my partner and I went into the shop room to experiment with an air compression tank and nozzle to find out how much pressure is required to move each type of ball in the competition. Alas, due to a communication error, I did not bring in the necessary types of balls to test. However, I did have a tennis ball in my car and was able to use that as a substitution. By using this ball and my prowess in mathematics, I was able to calculate the necessary air pressure needed to use the other types of balls.

While I was out, my partner met with Ms. Green after she attended a meeting about the Technology Dare event. In this meeting, My partner was able to discern some new ideas of what works and what does not in the area of our project.Meanwhile, my partner and I went to the shop again to continue testing with the air compressor and nozzle, this time armed with the necessary balls to test with. The nozzle had an opening of about 1/8 inch to allow air through. With such a focused force, it only took 25 PSI to move the cueball. However, we removed the convergent nozzle so that there was an opening with a diameter of about 1/3 inch. Even after we ratcheted up the PSI to 70, we were unable to move the cueball. Initially, I had designed my nozzle to be 1-1/4” in diameter. However, now that we were able to test, it has become abundantly clear that this must be adjusted somewhat.

Weekly Update 11/27-12/1
11/27
My partner and I discovered several flaws in our design and must discuss what we can do to fix this dilemma. Also, I must find some other sources to get a good, low price for a hose.
12/1My partner and I discussed how we could properly attach my portion of the project to his in the most structurally sound way to hopefully yield better output and prevent loss of airflow. My bid sheet has also been completed.

Weekly Update 11/20-11/24
11/20
I have compiled the list of materials necessary for the assembly of my completed product. Now I must prepare my bid sheet to be sent out to the board for consideration.
11/24
Fortunately, I do not need much funding for my project, as it is relatively low budget. Therefore, my bid sheet will only contain a hose to attach my nozzle and my partner’s pump to.

Weekly Update 11/13-11/17
11/13
I have been periodically updating my blog, hoping to make it as presentable as possible to be considered at a later date. I have relabeled several different posts to hopefully make it more organized.
11/17
The bid process for these supplies is due on December 4th, as it must be presented to the board shortly thereafter. My priority right now is to make my supply and parts list of the items that I need to build my finished product.

Mentor Contact 6
Student: Anthony Fischer
Date: 11/9/09
Contact: Paul Fischer (Father), Personal Visit
Reference: Nozzle Design
Questions: How do pressure washers work?
Discussion:
Today, my father and I ventured out of the safety of our home to excavate nozzles from several different locations that bore less than favorable conditions. We picked up three new nozzles, one of them from a pressure washer (unfortunately, it is still attached to the handle and is quite cumbersome). These are now in my car and I am driving to school tomorrow. I hope to play around with them with Sam and figure out how exactly some of these work, so perhaps we can find something we can change or add on to our own design.
