Re: CB350 Built by a teen (F***** problems, yay)
surgery has began on the tracy body... needed a break from engine work. decided to have the bodywork be a decoy tank with plastic tanks underneith it for a few reasons, including ease of work (wont need to seal tank) ease of maintenance (can lift the body/tail without having to deal with the weight of fuel in the tank) and safety (fiberglass likes to crack, not dent, something you dont want to have happen in the event of a crash).

Start...
Where I ended... Have to do some more thinking before doing further cutting. I've already removed more then half a pound of material... this body was made to last; the fiberglass is scary thick.

At this rate, it will be called: CB350 Built by a senior.
Just pokin at ya, Im interested to see what you think about doing to the bottom of that tank. Knowing composites myself, its not going to be easy to do right.

Re: CB350 Built by a teen (Composite Surgery)
hardest bit will be having to widen the body at its narrowest part... or cutting the frame and narrowing it for that super custom look... really leaning towards that at this point. frame will be properly braced following narrowing of the seat area of course =D
remember.... the body is just there to cover all the fun stuff. I'll be able to hide not only gas tanks in there but also tool kit, electronics, and storage compartment (small one =D)

And remember that the body shell must be securely fastened. Many years ago a guy by the name of Peter Williams - great rider and brilliant engineer, was racing a Norton with a one piece body and it came off and he had the most horrendous crash. He did recover but will never be the same. Seats and tanks must be secure - you actually put quite a lot of force through both as you ride around corners.
I know that this isn't a race bike, but you know what I'm saying.

Hmmm, You could use that body to cover up a steel tank...? It would seriousley save a LOT of PITA work down the road.
Widening is easy. You need to find your center line and cut it. Band saw works very well.
Then you need some spacers exactley as wide as what your adding. I used some steel squares I cut on a shear. With those, I put some actual duct tape (the metal stuff) on each piece to tape it to each half of my work piece. First one on the front, then on the back, then the middle and so on.
With that done I took some more steel and taped that to the top of that I was working on. I drilled holes through them and used cleco clamps to hold it all togther nicely. Then I placed those clips on the inside of the seat one at a time.
When they were on the inside I took the metal tape and made a skin so the FG wouldent fall through the space. When the tape/ skin was on the outside, I put the clips back on the outside of the seat and started glassing the inside.
When it kicked I sanded the outside of the seat, glassed, sanded, filled and so on...

Re: CB350 Built by a teen (Composite Surgery)
thanks for the info guys...
garage rat... issue with my case is that it only needs to be widened in the middle, and the whole body is a swooping beauty, so ill probably have to get creative. .
no work done today at all, been busy fixing dads bike, new wipers on truck, fixing uncles bicycle, a bunch of BS really.
college move in day is coming soon, it will probably have to get rolling before then so that I can bring it there? dont know.
THANKS TO MIKE DOCK FOR THE FINNED COVERS! came in the mail today =D

Re: CB350 Built by a teen (Composite Surgery)
One thing to think about i used to build bikes in my fraternity chapter room. took some pledges to help me carry the bike down and then would go to town... there is still hope when you are there. if you are moving into a dorm i woudl HIGLY recomend you leave it at home till it is closer to being done... dumb drunk college chicks like to sit on bikes and would destroy that thing

Smartest thing you could have done!! I spent 4 years on FSAE, and blame nearly all of my education and subsequent jobs on it! I spent more time in that shop than I did in class.
A word to the wise though...I don't know which school you are going to, or how serious they are, but if a freshman came in to our club just to use tools for his own purpose, he'd get kicked out real quick! We had too many kids coming in and leaving projects in the shop and taking advantage of just that, so we made a rule, if you left your project in the shop over night, expect it to be taken apart by the following morning I remember a few nights spent dismantling bicycles and dirt bikes!

haha... I'm going to rutgers university. I'm pretty damn serious about actually working for the team. I get the feeling (after having spoken to many many students) that I have a wee bit more mechanical knowledge then the majority of freshmen entering as mechies, so they will probably find SOME use for me ;D .

Werd! Don't bring anything cool or interesting to college! I brought my painstakingly restored, or at least 90% restored Triumph TR6 (ain't many of those around) up to my fraternity house thinking it would be relatively safe. It wasn't cool having five or six brothers try to climb into it and want to go zipping around campus!

Rutgers is a pretty cool set of guys. We were paddocked next to them at competition and they were fun to joke around with. They have a VERY fancy car in the realm of FSAE. Good luck!
