Operation Integrity Options

[amfab]

OK, well I had to have a thread title. I am calling it that because it will restore structural integrity to the car and I want to be able to say that the rust has been correctly repaired if I eventually sell the car, unlike the lack of integrity of the person who hid the rust to sell it.

Pictures below

The floor is a little shiny because there is still some mineral spirits on it from trying to get the tar off.

The open areas that you are seeing are after I wire brushed with knotted wire wheels on a grinder, then a carbide burr on a die grinder. While I will take some more off, what you see is getting close to good weldable metal.

First the longs:

The driver’s side is the worst. The bottom edges inside and out were full of holes, or very thin, so I cut the outside of the driver’s all the way off—except I haven’t got to the front under the door pillar yet.

I have cut out about 30 percent of the passenger’s side. The middle section is solid but I will replace it anyway. I started getting a little scared to take more out until I brace up the body.

The floor pan:

There are lots of sloppy welded patches and holes around the seams. The rear passenger’s and rear drivers quarters of the floor pan have been replaced with some plain steel—blue for some reason. The PO welded a solid bar on each side to mount the seat hinges. Sloppy, unground welds abound. There are some rust-through spots at the front of the pan that will need patching, but overall the pan in front of the cross member is solid.

Some patches in the lower firewall are solid.

Measuring diagonally, window frame to targa bar and straight back window frame to targa bar it is off no more than 1/8 inch. This changes depending upon doors open or closed or movement of the jack stands. The door gaps were never problems—maybe the driver’s side was a little wide. So it seems the car is pretty within spec and adjustable doorframe bars should be able to pull—or push—things to be good

Here is where I need advice. This is my plan, please give feedback:

1) Pull Wiring harness, speedometer cable and gas lines out of the center tunnel (What else is in there?) pull gas tank.


2) Pull doors and build adjustable bars to align doorframes

3) Continue to grind back to clean metal in the inside of the longs. Sandblast, then create internal angled patch pieces to repair the inner longitudinals from 18ga cold rolled. I am using michelko’s example see:

4) Cut off the majority of the inner rockers (The upper half or three quarters of the longs are very solid) and replace with inner rockers from Restoration Design.

5) Coat interiors of longs with Ospho then Eastwood frame coating

6) Patch any inner long parts to the area aft of the Restoration Design patch with 18ga cold rolled steel.

7) Install Brad Mayuer reinforcement kit over the longs

8) Cut rear floor quarters and cross member out

9) Weld in new rear floor panel and cross member, grinding out old welds and creating flanges from18ga where necessary—in the spots where there is no flange left in spots along the firewall and inner long

10) Remove and rebuild pedal cluster and create patches for small rust spots in the front of the footwells.

11) Sandblast interior and prime and paint.

12) Cut holes for front sway bar, sand blast and prime and paint bottom of gas tank area.

13) Install gas tank, new stainless gas lines and reinstall wiring harness.

Please give any feedback regarding my plan

Flap wheel generates too much heat. Too easy to warp the metal after you were so careful keeping things cool during welding.

I typically start with a cutting wheel mounted in a die grinder and used on edge (constantly moving) to take off the bulk of the weld but being careful not to touch the parent metal, or I take it down with a 2", 36g disc in an angle grinder depending on the weld, my mood, and which tool is handy. then switch to 80g 2" disc to take it down to the surface of the parent material. Finally, finish up with a conditioning disc. That said, I'm still very much a nube and things don't always go as planned. (IMG:style_emoticons/default/smile.gif) Lots' of good threads about grinding. McMark posted a nice video showing his technique http://www.914world.com/bbs2/index.php?showtopic=322374.

Dollisserie I like that.

Maybe its my fondness for flap wheels that is causing me the problems.
