  • Quick detour before hood reassembly:
    ​ This deep pitting around the nose of this hood is concerning. The rust has only breached in two spots for the moment but the advanced rust that lurks in behind it will certainly rear its ugly head in the future at some point.
    Click image for larger version  Name:	IMG_0577.jpg Views:	0 Size:	172.6 KB ID:	114373 Same goes for the underside, pitted and with the rust lurking just under that lap joint. There is no avoiding it as the water it will come into contact with is going to run down and settle along this leading edge and no matter how well its seam sealed and painted water always finds its way. After talking with my buddy, now was time to address it.
    Click image for larger version  Name:	IMG_0585.jpg Views:	0 Size:	216.4 KB ID:	114374 Its a complicated area and while both pieces are pitted I am 90% sure we'll get away without a patch repair. Just going to clean thoroughly and seal with epoxy and paint. With the left side out its technically half way there so now most certainly was the time if it was going to be addressed.
    Click image for larger version  Name:	IMG_0586.jpg Views:	0 Size:	268.8 KB ID:	114375 Only surprise is that this area wasn't rotted out entirely. Look at that old water line; this had a pool of water in it on more than one occasion.
    Click image for larger version  Name:	IMG_0587.jpg Views:	0 Size:	246.8 KB ID:	114376 Once the acid devours this rot I'm sure there will be a pin hole or two to close but they be easily soldered shut with a gas weld.
    Click image for larger version  Name:	IMG_0589.jpg Views:	0 Size:	209.5 KB ID:	114377 Though there remains some rust under the right and rear section of the substructure this is as far as we need to go. We'll all be long gone by the time those areas ever become an issue. My main concern is this rusty low spot where the water will try to settle again. Acid bath next.

    Thanks for looking!

        • Justin so sensible of you and your mate to decide to do that! As you say a few years and it would have showed up. Again I have to say it thank goodness mine is rust free. Never seen that repqir noted and made safe as you have done on any site.

          Well done,
          Roy

            Thanks Roy! Now was the moment to address these ticking time bombs while we were this far into it. This lower leading edge of the hood will always be exposed to moisture either from being washed, or driven in the occasional rain shower. It will pool along the trunk seal and go to work on that lapped underside leading edge or some water could also get by the hood handle seal allowing it in behind through the stud hole as it did initially. Now, no matter happens, all that old rust is gone and no longer growing. As I said earlier, we'll all be long gone before it becomes a problem again. See all the fun you're missing having a rust free hood? Thanks again! Justin

Hoods Crowned profile comparison along the edge of the fender much improved but there is a bit of metal finishing and hammer work of course yet to do. The true test will be after its actually hinged and mounted but a promising start so far.

                Thanks Roy! It will need some minor tweeking as it goes along with the fenders and the nose as their fitted together but definitely much improved over where it began...and now rust free up front.

            • Hinge mount refitting:
              Click image for larger version  Name:	IMG_0652.jpg Views:	0 Size:	152.1 KB ID:	114409 One more shot of the initial hood fitment just laying on there loose. Corner is tucked a little low here but all these misalignments are well within striking distance. The hood has to be mounted and latched before I can take it any further.
              Click image for larger version  Name:	IMG_0643.jpg Views:	0 Size:	495.7 KB ID:	114410 Now time to reset and remount the left hood hinge mounting flange.
              Click image for larger version  Name:	IMG_0644.jpg Views:	0 Size:	491.3 KB ID:	114411 Its pretty much going to go right back into its original position though with a slight change in approach angle so the hinge can remain centered in the pocket.
              Click image for larger version  Name:	IMG_0648.jpg Views:	3 Size:	517.1 KB ID:	114412 The original hammered over edges where limiting the amount of lateral movement so I hammered them back out flat and will reshape them over the substructure as before once its tacked into the needed position.
              Click image for larger version  Name:	IMG_0645.jpg Views:	3 Size:	182.1 KB ID:	114413 Mounting flange is bolted down to the hinge where it was marked in its best adjusted position before I dismantled the hood. Ready to tack weld this flange back into the sweet spot.

              • Hinge mount remounted.
                Click image for larger version  Name:	IMG_0664.jpg Views:	0 Size:	210.4 KB ID:	114415 Fore and aft placement of the flange on both the hinge and hood itself back into position before all the cutting. Initial tack weld laid down.
                Click image for larger version  Name:	IMG_0666.jpg Views:	0 Size:	510.0 KB ID:	114416 Eventually got enough tack welds along the outer edge to hold this sweet spot for hood removal. Backed the bolts loose to test for any tension. I'm shooting for a natural fit with no lateral loads going through the hinge from being forced over. So far so good.
                Click image for larger version  Name:	IMG_0668.jpg Views:	3 Size:	193.1 KB ID:	114417 Removed so I could lay down some good beads along the outer edge where the old gas welds originally were. I needed this side fully secured before attempting to work the other side into shape.
                Click image for larger version  Name:	IMG_0667.jpg Views:	3 Size:	210.8 KB ID:	114418 Going to have to use some heat to get this side over for a shaped fit. This mount is every bit of 16 gauge and the much thinner hood frame would stand little chance against it cold. The substructure would conform more to flange versus the other way around which is what I'm after.
                Click image for larger version  Name:	IMG_0670.jpg Views:	3 Size:	223.9 KB ID:	114419 After several series of heat and hammer work this side was now very close.

                • Click image for larger version  Name:	IMG_0671.jpg Views:	0 Size:	236.9 KB ID:	114421 Here is the correction from where it sat originally. The front of this flange is pretty much where it started but the back of it was swung outward about 5MM give or take so that it would sit flush against the hinge while centered in its pocket.
                  Click image for larger version  Name:	IMG_0672.jpg Views:	0 Size:	546.3 KB ID:	114422 Hood remounted for another test fit after all that heating and hammering just to be sure before I committed to anymore welding. So far so good, everything staying centered and flush without force. No amount of beating to either the hood or hinge would have overcome that 5mm's worth of misalignment. It would have turned into a mud hole; this way it all fits together natural and nice and the hood will be available for removal and installation with hinges installed as it should be without too much drama. I'll be testing for that here shortly.

                  Thanks for looking!

                  • Very neat way of getting that aii sorted Justin. Nice the hood can be taken off and on with no drama. Will you still use some datum holes in the hinge plates as they did at the factory to always get the hood in the correct position? ( maybe the original ones are close )

                      Thanks Roy, I've delt with a couple of hoods that were sort of a forced fit and the gaps kept changing on me slightly as the bodywork progressed all the way past final paint. Didn't want that issue again so the goal is a natural relaxed fit right out of the gate. Since we're almost starting from scratch the Datum holes were filled on the mounting flanges and will be redrilled to match the hinges once again to lock in the final gapped position after the front end is reconstructed.

                    Click image for larger version  Name:	IMG_0678.jpg Views:	0 Size:	478.2 KB ID:	114429 No issues on the right side.

The hood will still need some shape adjustments along its edge as the progress continues but for now we've got a hood that operates just as it should.

                      • Super effort Justin I have learn't a lot on this exercise. I think if I were 50 years younger I would have liked to try some of the things you have been doing but left it too late! But.. I mentioned I had a small gap issue on the front bonnet lid on my car well today I got my 14mm spanners out and would you believe really improved the gap no end. I was delighted. Once you carefully think about the hinge adjustments and the closure of the front locking bolt I have now got it back to when the bonnet lid was when I bought it in the 60's. I have had the lid off a number of times and obviously did not pay good enough attention. It is true now the hinges alignment holes are only as original on the l/side the r/side one does not now line up perfectly as before but the gap is so much better!

                        Sorry to mess up your thread with my efforts today.

                          Thank you Roy! No need for apologies, thanks for sharing and congratulations on improving the gap and overall fitment of your hood. There really are a lot of contributing factors on how the hood ultimately sits in there once its closed fully. Even a slight bend in the latch shank can pull the hood to favor one side or the other depending on how that bend is oriented. I've been through all of that before. This is my main reason for having the hinges and latch all fit tension free out of the gate. If its a force fit the gaps and fitment will change slightly every time its messed with. Thanks again. Justin

Mechanism/base was engaged onto the upper shank then the hood was lowered down and the back of the base was marked at the center line.
                        Click image for larger version  Name:	IMG_0687.jpg Views:	0 Size:	561.1 KB ID:	114437 Then the for and aft placement was dialed against the installed closing wall.

No danger of getting locked out of the trunk so now was the time to find if the angles and placement was good or if it was going to jamb. Released just fine though the true test will be after the upper part of this base gets a tack weld. A promising start anyway.
