Volvo Amazon Rear Arch Repairs: Update

 


This post is a short update and will not feature much in the way of photographic documentation I'm afraid.  I have not been as diligent with my camera as I should be.

Following the O/S rear chassis and inner wheel tub repairs (see previous post), I turned my attention to the new inner arch panels. These pressings look great and come highly recommended. It has been my plan for a good while to use these as the structure from which to rebuild the whole of the rear quarters, but (surprise, surprise) I have hit some problems. 

The first issue seems to be with the fit to the outer arches. I have new repair sections for these and so I thought that the best way to start would be to offer these up together, expecting them to clip together precisely; if only. I spent an entire day measuring, making card templates and trying to work out how they might marry up. I can tell you that the radius of the inner repair is not by default the same as the outer. This threw me completely. 

Of course the existing rear wheel arches are so corroded that it was difficult to work out which of the two radius might be out. In the end I took my panels and my templates round to my friend's garage to offer them up to his car; a very nice and completely unrestored '63 example. We managed to establish that the radius of the outer arch sections were the correct ones and that the inner sections were narrow to the tune of around 4cm. 

I approached the supplier, who were very helpful and they in fact contacted a local (to them) professional bodyshop that they knew to have fitted the same panels. The message that came back was that they will fit, with a bit of "stretching and fettling". I went back to my car and took some measurements of the inside of the panel, where the two halves of the wheel tube join; these were much more favourable. I concluded that the technique would be to fit to the inside first, then fit the outers to the rear wing, then 'stretch' the inner arch to meet the outer. 


Here lies the second issue and my biggest dilemma, how to fit the inner arches to the existing wheel tubs. Do I cut and bodge the new panels to let them in to the existing tubs, or should I completely remove the original outer tubs (inner arches) and recreate the factory spot welded fitting. My inclination is to do the latter (i.e. do it properly), but I cannot see how I can effectively achieve that without removing the entire rear wing. Right now, that's a bit scary! If I do this, should I fit the new outer arches before I remove the rear wings? Will I be able to successfully reattach the wings?  If it goes badly I could end up needing new ones which are expensive and would severely dent the budget. There might be a time saving though, assuming that they are a good fit... I need to do some more thinking.

So the update is that just like the battery box repairs, I have decide to leave this challenge for the time being and switch to something that I am confident that I am ready to tackle, the O/S boot (trunk) floor...

Boot (Trunk) Excavation

As I suspect you are aware, issues with rot in the boot (trunk) of the Volvo 120 series are common and my Amazon is no exception. Over the years it has been 'repaired' a number of times and not always sympathetically. I have made a start removing the filler and the patchwork of metal plates that make up the n/s and the floor next to the spare wheel well.  I've ground off some of the welds, chiselled and bent back the non-original metal.  As I have already reported the lower rear quarter replacement panels are definitely not correctly positioned but I have successfully managed to uncover the original boot floor which although is in a very poor condition, does give me some points of reference for the rebuild. Incidentally, a word of warning. I had to remove a lot of seam sealer and I really should have been wearing gloves. A slip with the scraper brought the session to a rapid conclusion. I was lucky not to end up in A&E. Now that I have investigated more tho...

Tooling Up: DIY Sheet Metal Brake

My new 1mm sheet steel has arrived, along with some additional angle and flat bar... but more of that in a moment. Using the refined ply forms , I have now made the boot floor rear edge piece again and I am much happier with it.  Going for the extra gauge steel was definitely the right decision and this new panel feels much more substantial. I have had a full test fitting with all panels, which is looking pretty good. The next issue concerns the rear inner arch to which spare wheel well side and floor is to be attached. There is some rust here and so this will need to be repaired before the really serious welding/reconstruction of the boot floor can begin. Although only a relatively small area, complex curves and profiles need to be created. I realised then that I had need of more fabrication tools. Here then is a description of how I fashioned a DIY sheet metal brake; a means by which I can easily and precisely create folds in sheet metal of up to around 90˚or so. This constructio...

Volvo Amazon Chassis Repairs

As suggested in my recent post, the job I originally planned at this point was to repair the battery tray which is in a bit of a state. However, even after an extensive staring, prodding and rumination, I still haven't come up with a strategy. The curves and swaging in this pressing are really quite complex, I am simply not ready to tackle this.  "Does it really matter what it looks like?" I hear you cry, "Won't it be hidden?" Well, actually I think it does, not least of all as I am planning to relocate the battery to the boot (trunk) and utilise the tray in some other way (the current thinking is to locate an oil catcher here, which is required for competition). If so, the repairs will indeed be visible. I've decided to ignore it for the time being and come back to it later. Instead I have turned my attention to the rear arches, starting with the offside. I knew that there are some repairs required to the chassis and the area above the spring locator. I...
