Finally got working on the rear arches over the last week. We started with the nearside as it was the ‘better’ of the two!
All the bad metal on both the outer and inner arch was cut away with the air hacksaw and the paint on the surrounding areas removed with a belt sander so we could see what we were working with. Surprisingly, given how bad the arch looked initially it wasn’t that long before we hit good metal.
Once this was done, Steve (the welder) was able to assess how much of the replacement arch we’d need to use. In the end we only used a small section of the new panel. This was partly because we didn’t really need to use it all, but also to minimise the likelihood of the bodywork warping when the new section was welded into place.
Given that some of the inner arch was also shot we salvaged a ‘replacement’ section from the cut-off arches I’d got from
markh a few months ago. To get that Steve just drilled out the original spot welds along the edge and ‘hey presto’ off it came.
Once this was cut to size and welded into place we cut up the new panel to the necessary size so that it could be joggled to fit into place with a small section of it being inserted behind the existing body panel.
Before this was welded into place though all the bare areas were sprayed with weld through primer (Normfest Elox). Then we applied some PU adhesive sealant (Tiger Seal) along the existing inner arch so that when the joggled repair panel was slipped into place it would help provide a decent seal between the layers of metal.
That done the repair panel was clamped into place and then tack welds were applied at about 6” intervals, then tack welds were applied in between each of the first series before Steve laid down some continuous welds to finish things off. The idea behind this approach was to prevent the panel from warping as much as possible and it certainly seemed to work on the whole, but there is still some warping visible.
Next we drilled some holes in the outer arch rim to expose the inner arch below and then through these holes we were able to tack weld the two panels together thus giving extra strength to the repaired arches.
Finally, as Poppy is still sat outside during the day, the whole area was sprayed with some zinc primer (Normfest Galva 97) just to keep the nasty rust at bay.
Right now the repaired area still looks a little rough, but once we go over the welds with the belt sander and then prep the body for paint everything should look good.
Then it was time to turn our attentions to the driver’s side rear arch. When I removed the bodykit a few weeks back this was by far the worst area of the car. As you’ll see from the photos, in addition to cutting off the arch rim we had to cut out quite a large area of the rear panel to the front of the arch and also down into the outer sill.
Overall the work involved was pretty much the same as with the passenger side and we followed exactly the same stages when affixing the new section. On this side though there was also a large area of the inner wheel tub that needed to be replaced. If you look back at the photos I posted after I stripped out the interior you’ll see there was an awful lot of damage in there. It was so bad not only could you see daylight through the hole, but I could have fitted my hand into the gap!
Steve rather cleverly used some of the unused metal left over from the second repair panel to form a plate, which he then cut to size and welded into place along with a small section of inner arch salvaged from one of the cut-off arches (from
markh).
One thing I hadn’t noticed until this week is that there must have been a fair amount of work done on the driver’s side rear quarter before I bought her in 1993. Two reasons I say this. Firstly, where I’d taken the trim off we noticed that the swage line between the rear arch and the passenger door shut is almost non-existent. Secondly, in cutting out the rusted section of metal we found that underneath the paint there’s an awful lot of filler, which probably explains the fairly non-existent swage line. Still that’s something to worry about another day.
So, that’s how things are at the moment. I have to say I’m really pleased with how she’s came on over the last couple of weeks and hope to have more to report soon.
