Heres some renderings of the chassis I am designing w/cad.

I still need to cut the holes for the bearing support and suspension hinges (gonna beef those areas 1st), and might widen the chassis a bit. The front area would have to be bent w/a vise after the chassis was cut. The bearing support and battery hold down posts would be seperate pieces.

I dont know anything about metalwork:confused:

if you can keep it as a tub then that would be great,, i dont like the open sided design of the carbon fiber..

First let me say i like the design, and i'm impressed you've gotten that much done.

now let me comment.

to keep it like that <tubbed>would cost HUGE amounts of money for material and machining time.

the bar stock blanks would have to be as think as the thickest part of the out side wall, and the machine time and tooling would run you more than the project is worth.

I've though about this as a project, alot. The most efficent way to do it would be to make it like a buggy chassis, meaning having a plastic tubbed side bolted to a flat alloy chassis. the other issue is the Kick up. If you are going to manufacture the chassis out of alloy that won't tweak when slammed into a curb @ 45mph, you will not be able to bend the kick into the main chassis design. It will have to be made as a add on, (sort of like wha they did in the HSE chassis)

I'm not saying this to knock you, but rather to help put you on the right path.

I have alot of experience with metalworking, prototyping and production so i figured i'd just pass on some knowledge.

Thanks Chris I appreaciate any feedback!

Let me ask you this, can the sides be a piece of aluminum that bolts/screws on?

The kick-up could it be machined from the same piece of billet? Or would a 2 piece design be better??

yes the sides can be aluminum, however they often are not b/c you can realize weight and cost savings by using a composite (plastic)

IMHO, a two piece design would be much more practical <from a manufacturing stand point> Mostly because the problems that can occur by stamping softer aluminum.

Also a two piece design could also be applied to a different material such as CF with minimal redesign.

The benefits of a one piece design are strength and rigidity.



hope this helps

Ok heres some more sample pics w/some revisions..

I made the raised sides seperate pieces but haven't decided how they will attach or what the will be made of:confused: I cut the slots for the bearing support out and reccesed the screw holes below it.

Rick Delten,

Excellent job. I cannot wait to see the prototype :)
Thanks for keeping us in the loop here :)

Quietfly, thanks for the input, as usual constructive comments!

once again thanks guys

Dont go too wide on the chassis, theres not much room left to widen with the body as it is.. Maybe 5mm on each side at best..
