So... I am going to attempt to re-attach the windshield frame on my teener. The welder i currently have at my disposal is a flux stick welder and im afraid that this thing will just burn holes right through the factory steel. I know that mig is better but this is available to me and it is already a hack job so (IMG:style_emoticons/default/welder.gif) and (IMG:style_emoticons/default/smash.gif) to get me (IMG:style_emoticons/default/driving.gif) . Any input on this subject will help.

Eastwood sells a "stitch welder" for ac welders. It turns the amperage on and off at short intervals and works as good as a ac welder can on thin sheetmetal. I've had one for 20 years and use to use it a lot but have gone on to mig and tig. Most parts of the body are about 17 ga. Someone thats cut the windshield will need to chime in though.

i could be wrong but i believe that the w/s frame is a little thicker than the rest of the body panels. So i should be ok with the flux weld... sloppy but sufficient.

If it's cut off why can't you see the thickness?

A little careful work with a file will take off the edge.
Good luck with the stick welder. Yer gonna have fun. (IMG:style_emoticons/default/welder.gif) |

Any input on this subject will help. Congrats on bringing your 914 back to its original configuration. I would suggest of course like everyone else that you use a wire feed welder and before you weld it back together that you take some careful measurements and actually then tack the frame and place a top and a windshield in to check the fit. Secondly I would weld some reinforcement steel inside the frame as just welding it back together will not make it as strong as it once was now that it is cut in half. Years ago we repaired quite a few rolled 914s and if the reinforcements are not welded in the frame sturucture is weak and unsafe. |

About the top... there is a targa top but no targa bar, soo.... i dont think that it will be exactly "back to original". But good enough for gov'ment work, ya know.

Here's a crude sketch. Sorry I can't even draw stick people.
Sleeve the body section of the post. Slide the upper section over the sleeve and you have a back up strip to weld to. Attached thumbnail(s) |

(IMG:style_emoticons/default/agree.gif) rather than a butt weld right? I was even thinking of cutting a hole with a hole saw to weld the interior of it as well (IMG:style_emoticons/default/idea.gif) Is this excessive or just a bad idea??

(IMG:style_emoticons/default/headbang.gif) Don't........... (IMG:style_emoticons/default/headbang.gif) get a mig setup. Because it is too high amperage or because its sloppy? Extrapolate please. |

Do yourself a huge favor. Borrow the welder, find some scrap 20 gauge and try welding it BEFORE you attack the car with it. Then go find a mig setup to borrow. If you still want to try it then do like Rick illustrated. Plug weld the sleeve. Trying to butt weld with a stick welder will most likely end in disaster.

The sleeve will be stronger the the original section of the post. I would use 18 GA. Form it to fit tightly in the post and plug weld the lower section. |

Good to know that was my original concern. Maybe my friends father-in-law will let me use his TIG.

I agree with Scottyb - no to the stick.
That's how I learned, and it's great for thick parts, but REALLY sucks on 914 sheet metal. It will blow big holes through that metal in a heartbeat unless it is backed up with a chill plate. Because the frame is a tube, you can't get the chill plate in there. Use George's suggestions for adding reinforcement and the cut the frame to fit with a real windshield in place. Then remove the windshield, hold the frame in place and tack that sucker in place with the stick. A tack weld or two on each side should suffice. Then stop. Take it to somebody with a MIG or TIG setup so you won't have to do this over and over and.... |
