The Making of the Last Vetter Fairing

| My goal is to live better on less energy. I am designing the ultimate fuel economy and rider comfort at 70 mph, into a 30 mph headwind with 4 bags of groceries. Oh yes... in a garage full of vehicles, I want this to be so convenient, so much fun and so comfortable that it is my first choice.
What is the formula? How much horsepower? What will it look like? Follow my progress in the following web pages as I learn the truth. This is where I apply everything I know about consuming less fuel and liking it. Begin the story Feb 20, 2008, below |

Americans have developed such a thirst for fuel that we cannot generate enough from our own resources. Today, we import three of every four gallons from other countries. Some of these countries hate us and want to destroy us. Guess where their money comes from. We need do reduce our fuel consumption by 75%. Our 7 mpg trucks need to get 28 mpg. Our 25 mpg cars need to get 100 mpg. Our 40 mpg motorcycles need to get 160 mpg. If we did this, we would not have to import anybody else’s fuel. |

3 of every 4 gallons is imported

This is my passion The goal is to make a cycle we will want to ride across country that gets at least 160 miles per gallon. We must begin with the right horsepower and then streamline it. Here you may follow along in my design process. |

We must all do our part to consume less fuel.

| First, I thought you'd like to read this E mail from 2009:
Hi Craig: It seems that your "High Mileage Luxury Touring Bike" of 1981 would actually meet, or at least come very close to, the requirements of the Freedom Machine. 100+ mpg highways speeds? Yes. Carrying capacity? In the tailfairing... not quite sure if it'd fit 4 bags of groceries but it looks like it could fit at least 2. So what am I missing? Why reinvent what's already been done? Best regards, Keith My reply pretty much explains what I am doing here: "Hi Keith: These are a good questions. That was when the speed limit was 55. There is a very big difference in 70 with a 30 mph headwind which makes it like a 100 mph wind. The 1981 machine was very good in side winds. Very good indeed. However, it was a little awkward getting on and off the machine and I got wet in the rain. Storage was decidedly too little. On the new machine, being developed here, I had hoped to be able to have the sides continuous... with no breaks, for superior streamlining, and better weather protection, which was another goal. The 1981 design was a "one-off." This time, I would like to end up with pieces for a kit that can be used by other dreamers. I want it to fit everything. For example, shipping is being addressed. Can you imagine how much it would cost to ship the 1981 design? Thus, I began anew." Craig Vetter Dec 10, 2009 |

| It is my hope to inspire you to take the matter into your own hands and see for yourself what is possible. As you read the following chapters, you will notice that the Freedom Machine has been made entirely with simple tools which most of you already have in your workshops.
Do not expect Detroit or Japan or our government to solve these problems. "Doing more with less" does not make anybody money. But, "Doing more with less" can make our country stronger. Follow along. See how easy and how much fun this is. I hope you get inspired. We can do this together. Begin now: |

| Pick a machine with the right horsepower. Something that sets low with about 15-18 hp. should be a good beginning. | |||||||||||||||||||||||||||||||||||||||
| Step one is to photograph the key views and size them in PhotoShop | |||||||||||||||||||||||||||||||||||||||
|
Streamline it

| Streamline it: Streamlining is round at the front... pointed at the rear. Streamlining allows less power to do more | |||||||||||||||||||||||||||||||||||||||
| Step two is to do a quick sketch of a streamlined shape.
More is to be gained by adding a tail that can be gained at the front |

| I already have the famous 470mpg Streamliner body parts which are perfect for "bent over" riding. But, I want to sit up. So, lets see how close the fit will be.
Step three is to put my existing Streamliner fairing over the Helix and see how close they fit. PhotoShop makes it easy We can see that they are much too small and will need to be "stretched" |

| Leaving the ends together but widening the center will make them fit | |||||||||||||||||||||||||||||||||||||||
| Step four is to cut and reposition the Streamliner parts to see how close they can come to my sketch
Actually, it may be easier to begin from scratch. We'll see. |
|||||||||||||||||||||||||||||||||||||||
| Cut it, pull it apart and tip the rear section up. Add a head fairing to help smooth the air behind my helmet. | |||||||||||||||||||||||||||||||||||||||

If you have not yet watched my DVD, How they Got 470 mpg it is time to get it for the basic foundation for what we are doing here
