Welding the Jack Points

Welding all the things

The sheet metal on the canals around the jack points seen as the four holes at under the doors were quite rusted out. Actually I had to weld three out of the four.

The jack points themselves were rust free when removing the sheet metal in the canals around the jack holes. They are made out of very thick steel and also have the protection of having the canals as protection. The canal sheet metal on the other hand didn’t cope so well with the road salt and it is especially exposed at the corner where it meets the wheel wall. Here a lot of dirt and salt can accumulate  behind the plastic inner fender and it also is exposed from the engine and roof water drains. At the picture under you can see a hole straight into the coupe where it is next to the engine water drain.

When welding it is very important to treat both sides of the weld with anti rust paint to keep it from rusting again, and also do this soon after the welding before the rust can attack the weld seam.

The rear right jack point also had to be welded as can be seen on the picture below. This is also the point where I got a new camera, so there is a huge difference in picture quality.

When seeing how thin the canals are and the rigid thick structure of the jack points, one can see how extremely import it is to never jack up the car outside the designated areas (you might end up with the jacks going straight through the car).

I didn’t bother taking pictures of the third one since it was much less of a hole and not so spectacular as these two.
