See last post. Welding and rubber sealant removal coming to the end. Thanks.
Haven't been very active for a couple of years. Partly because the 911 has taken up my time. So I am finally getting around to rust repair on my '76. The floors have rusted through so I have been working on the layer cake that makes up the right side longitudinal, focused on the hell region. The rust has affected both the inner pieces as well as the outer ones, and it is concentrated where all of the pieces come together. I have cut away the pitted and perforated metal. My question is as follows. I am addressing the problem by restoring each piece to produce a longitudinal as it came from the factory. For example. In this case I made a piece to restore the tab of the forward inner layer of the outside long. Then I added a piece to restore the rear inner layer piece the overlaps: Then I have made a patch for the outer wheel house piece to produce the outer layer. The patches are butt welded to good metal on the original pieces and shaped to reproduce the originals. Here is the question. Is this really best practice? For example, instead of making a bunch of pieces that join together to match the original I could use a single sheet that replaces them all at once. With fewer butt welds and seams. My method so far has been heavily influenced by threads from people I admire here on the world. You folks make nice welds. |

Yep. Moving to the outside layer cake. I really hoped that the left side would be better, but it is slightly worse. Looks like the Counting Crows hit the nail squarely on the head. It was probably Raining in Baltimore much of this car's life. At any rate this shows three layers of metal. There is the front outer long: rusted at the last two inches. This panel is made by RD, but that is a lot of cutting to patch that little part. In the rear there is the outer layer that goes on to make the wheel house and then a strengthening layer (with the punched large holes. This is made out of stronger steel. Fortunately I have a punch set. Not sure how close a match they are yet. Farther in the hole are the weld back sides of the repair of the inside long. Screws poking in are temporary: have to get them out and finish those plug welds. Question for anyone who might know. Is it possible to replace the jack point without cutting out the fender and sill? I don't see how, but still wonder. |

Been awhile but in the mean time I have been remodeling some rooms, rebuilding the 911 engine, and getting gifts made for x-mas (shaping and grinding Damascus steel kitchen knives).
Returning to the left side: like the right side I worked from inside out. Replacing the rear end of one piece. This inner piece to the rear is overlapping the first patch. As before, I am replacing ends or bottom areas of a large piece. Matching the holes originally there was a PITA and perhaps I should have just them out, but here they are a bit of the ugly. The hole towards the front is behind a depression in the next piece that overlaps. The depression is for the jack point. Attached thumbnail(s) |
