Least stressed member
Nitrogeno25 - 12/2/07 at 02:56 PM

Are there any member of the chassis candidates for thinner wall (maybe 18 awg).

I'm thinking of the least stressed memebers or the shortest ones. What about the vertical tubes?

Thanks a lot.

If it's any help, when caterham did the csr chassis they actually increased some tube wall thickness' in order to make it more rigid.

Just read the Cymtrics chassis mods... they'll tell you ways to reduce weight AND increase torsional stiffness.

I think that I'm probably the least stressed member, but I'm way over 18 gauge in thickness.

I wake up with a stressed member most mornings, im sure I aint the only one....

You can safely make the whole chassis out of 18g tube.

Increasing the wall thickness of the tubes add pretty much zero stiffness (actually it adds none, the only thing they affect is the braking/buckling strain/strength of the tube), much better off strategically adding thinner tubes in various locations to increase stiffness.
