NFA Vehicles Type Eleven

The Type Eleven has been constructed, after a long pause. For those of you following the progress of the NFA Vehicles "Think Tank" , you know it's been some time since Type Ten was completed. We started in 1986 with Type 1 and Type 2. Type 3 came in 1987. Type 4 was built in 1988. Type 5 and Type 6 date back to 1989. Type 7 was designed in 1992 by my Daughter Mellisa and her friend Patricia, and built the same year. Type 8 is being saved for last*. Type 9, designed by Mellisa, was built in Winter 1994-95. Type Ten has had many Variants, with the current #10 having been built in 2002.
Type Eleven comes along just in time for the 2011 model year, so I suspect there will be some confusion as to whether the "Eleven" refers to the model number or the year it was introduced?
Please search the forums if you wish to see photos of the previous "Human Powered Vehicles" which NFA Vehicles has produced.
Today, I present the NFA Vehicles Type Eleven, in Color Photographs:











This Prototype contains NO Fiberglass, it is all Corrugated Plastic. This saved hundreds of hours of Labor. Some Steel bolts were used (quarter inch with 20 threads per inch, between 3/4 and an inch and a half long).

The Front Box Fairing is twelve inches wide and the Front surface is angled to beat the wind.

I have more photographs, hold on...

Just a sketch . Oops, this NOT the Type Eleven, it's the Type Ten, on twenty inch wheels.



This is a picture of the Type Ten as it looks CURRENTLY.



The Type 9, as my Daughter designed it.



The last Type 9 Fiberglass Ladies Bicycle drawing, in watercolor.



The Type 9 Fiberglass Ladies Bicycle , on 24 inch wheels.

I just wanted to pass the latest sketch around, for your perusal and comments. I want to do the rear panniers in Fiberglass, instead of Coroplast (Corrugated Plastic). I will have some old Coroplast Panneirs left over, maybe I will donate them to a Thrift Store?



The Fairing in the first sketch is a throwback to the Type 3, which had a "Dustbin Fairing" B&W photo, circa 1987.



The Type Ten Fairing is actually an Apple iMac Computer Case, which saved a lot of work, compared to hand-laid fiberglass.



The Type Eleven has new Panniers, double the size of the original panniers (Black Coroplast instead of White).

This has been an update from the NFA Vehicles Laboratory.

I want you to see these new videos. I had to replace the supports under my Coroplast Aerodynamic Spoiler Basket, as the tire was rubbing the bottom of the basket. I used aircraft plywood and five layers of fiberglass to bond and support the structure. The thing is, the new supports can also support lower Cg Panniers on either side.

I always post updates on the current status of my prototypes. I want this thread to be a valuable resource for the do-it-yourselfer.

A couple of notes about the materials; 1) Coroplast tm is a lot cheaper than Fiberglass. Coroplast comes in the form of boards, and can be folded. Whereas Fiberglass arrives in a liquid state, and requires a mold, and the mold costs as much as the finished Fairing.
2) Aircraft Plywood is much better than regular everyday lumberyard Plywood. More layers (thiner layers) and waterproof glue holding the plies together. I learnt my lesson from the Type 6 Velomobile, which was ruined after sitting outside for a couple of years, and the 1/4 inch "Luan" plywood (in the bulkheads) rotted out.

I want to note that the fiberglass on the fork, in the above video, has the first two layers wrapped around the fork blade, and joined together on the inside (the side facing the wheel) Then the next three layers wrap around the plywood on the outside, thus "sandwiching" the plywood. I want to pass this tip along as I doubt the structure would hold together otherwise.

This had to be done on account the Coroplast was bowing outwards and the tire was rubbing the bottom of the spoiler/basket. I saved a lot of money by not buying a touring fork.

Note that in the construction of the Battery Box, a foam board was used, rather than plywood or coroplast.
