Thanks! Yes, January 2011. We have had two terrible winters now. I was forced to remove snow from the roofs of my house and garage. I measured the snow on my garage roof and it was 4,7 feet high at its most

A few photos from the disassembly. This car was one of the nicest cars I have ever come across to work on! There were not one single bolt that was stuck. It all went very smooth.
However I found several bolts that were not correctly tightened and a few that were broken in two. several of them in the driveline Im very glad that nothing happened during the two summers I used it...

The chassie finally almost completely stripped. Time for sandblasting before welding.

I found this date on the frame. If the date means that the frame was assembled August 5:th 1968 it means the frame is 2 days younger than me! quite a coincidence.

Wanted to share some photos of the frame after blasting. It was in a perfect shape. Not one rust hole to be found. It looked like it could have been manufactured yesterday.

But the welds, what did they do in 1968???? I was quite shocked by the poor quality. However, they did something correct back then since the frame still was in good shape after more than 40 years.

I decided to manufacture a jig for the frame to keep it fixed during the welding.
I had a few beams that I thought would be strong enough. I aligned the beams to be completely horizontal in all directions and then they were welded together keeping track of the alignment the whole time. It turned out pretty ok (within 2mm).

The Jerry cans and the welding machine is not a good combination I think

The frame was positioned 500mm above the jig. This gave good acess to all areas of the frame.
Aligned the frame to be level with the jig to give a fixed surface to measure everything from, before, during and after.
Welded the frame to the jig using 50x50mm beams (2"x2").
This work took me a few evenings to finish but I think it was well worth it.

(Jerry cans now removed...)

That's why I asked if you welded the frame

Back then they got a few monkeys from the local zoo and gave them stick welders to play with.....

Some photos of the frame welding. I started by grinding all starts and stops of the old welds to smooth them out as well as remowing all sections of bad quality welds. Most of them looks to be of bad quality but evidently the frame is ok.
I measured the frame thoroughly according to the C3 frame drawings, taking notes on all measurements before I started welding. By this I had good reference measurements to compare with after the frame was finished.

Shifted the weld sequence from underside of the frame to the upside the whole time and also welding on many different locations to avoid warping and heat build up. This took several evenings to complete for me.

The rear kick up reinforcement beam was boxed. I have not seen this done before but it felt like a good idea.
I was really surprised by the soft steel in the frame. It was also quite difficult to avoid alot of weld spray. Tried to change the weld parameters as well as protective gas flow. No success Perhaps a different gas would have been better but my guess is that the steel used for theese frames are full of contaminations.
