I'm think about restoring my 914 this coming winter. While I have it down to bare metal I was thinking about seam welding the body to stiffing up a 30 year old flexing body. Has anybody done this? I'd just like to hear the "Pro's & Con's" on why or why not to do this.
Thanks, Ralph 74 2.0 |

Its a LOT of work. But I feel it helps. Weld for 2 inches..leave 1-2 inches.
The main places I feel need attention: All of the rear end from the B pillars back. Everything forward from the A pillars. You cant go wrong with welding it all up. You can however tweak the chassis if you spend all weekend trying to do it at once. Spread it out over a week or so. Give the tub time to cool down. B |

I assume it's all the spot welded body panel joints.
My question is, B, are you advocating manual stitch welding or do you literaly mean weld 2" and leave 2" unwelded along the seams. |

Feel under the car at the rocker panel. There is two pieces of metal that form a 'seam" where the sheet metal is spot welded together. This stands up at a right angle about 1/4 to 3/8 of an inch. "Seam welding" is welding this connection continuously.

Hey Paul.....
In order to make your car even lighter, have you considered removing some of the welds?? (IMG:style_emoticons/default/smile.gif) |

Literally stitch it. There is no need to lay continuous beads (as far as I'm concerned) I have done it and seen it done many times on race 914's.

You guys are soooo funny!!! (IMG:style_emoticons/default/rolleyes.gif) (IMG:style_emoticons/default/rolleyes.gif) (IMG:style_emoticons/default/rolleyes.gif)
Weight saving ideas: 1. I could acid dip it, but it may just be gone when I go to pull it out of the tank. 2. I thought I'd just paint it with one coat of paint. I'll buy a pint and thin it out. 3. I could run it only with a can of STP Oil Treatment in it and NO oil. |

Brad, Thanks for the reply. I'll most likely weld 2" then go a foot on the long runs first day (and let things cool off), then keep repeating each day till I have the 2" weld & 1" to 2" space.
Aaron, I'll be using a Mig Welder (wire spool feed). They are really good for sheet metal. Thanks for all the input, Ralph 74 2.0 |

Mind if I ask which seams you're planning on welding? All of 'em?

Ginter, Yes. Well most all the spot welded seams.
But not things like the headlight buckets & other non-structural items. Ralph 74 2.0 |

No problem Ralph. I'm glad we have another east coast 914 guy on the BBS.
Let me know if you needs pics of how it is "typically" done. Wait.. I need to start charging 5$ for every pic I post....LOL B |
