When a roll cage bar/chassis tube goes through a firewall, what do you do? Do you cut the hole close and then weld around it, use seam sealer, just live with a small gap? I am trying to decide what to do with bars connecting the cage to the front and rear suspension points. Thanks, John |

Aluminum cover-plates (two halves) riveted in position.
No need for a precision through hole that way. |

QUOTE(Racer Chris @ May 2 2011, 02:52 PM)  Aluminum cover-plates (two halves) riveted in position. No need for a precision through hole that way. So it appears from both replies that you should avoid a structural joint between the cage and the sheet metal it may pass through? (IMG:style_emoticons/default/confused24.gif) This seems reasonable since the elements in the roll cage should only be in tension or compression. Joining them to the sheet metal as they pass though would apply bending loads as the chassis deflected. |
