Finally had some time to make progress.
I did bits and bobs over the time, and my camera charger has finally arrived, so here's couple of pictures.
I've cleared the side panel next to the sliding doors completely to see what does it look like underneath
hammered the s**t out of it to get it to the original shape. I have just realised I didn't take a picture of it completely cleared, but it will be visible on other pictures.
Oh yeah, that reminds me - I did cut out the rear wheel arch some time ago too. And replaced it. Since I didn't have time to weld it in, I was driving around with ductape holding it in place, ehm ehm
But then I did weld it in and primed so it doesn't catch any flu or WORMS
Then I cut out the bottom half of this panel - as this was very rusty and damaged. Well - I wouldn't call it panel, more like hole where the panel should have been.
And then I started to rebuild the box
I know, I know - the welding is not the best, but the rear panel is all rusty and even though I brushed it, to get 100% perfect results I would have to replace the rear too, but I don't have so much steel sheets and despite the bit of rust that panel is in reasonably good condition.
And then I tried and welded in a steel sheet to replace the panel. Just so you know, if I had to do it all over again, I would get a proper replacement panel...
It was loads of work to get the steel sheet fit the shape - Muttly I envy you!
Yes - the shiny bit at the bottom of the panel is self made return that was no longer there (rusted off), so I made my own. I will be hammering that to get it into proper place.
It is only spot-welded as I didn't want the steel sheet to bend uncontrolably, and YES I did burn couple of holes which I'll be filling in
Furtermore - it turned out to be about 2cm shorter then I needed it
so there is slight gap between the panel and the replaced wheel arch, but I'll be welding in a piece of steel to bridge new panel with the wheel arch at the arch bend. Making it as invisible as possible if that makes sense...
I spent most of tis morning trying to remove the sliding doors, which proved impossible. I actually baked my drill in attempt to unscrew the bolts holding the doors to the top and bottom rails... Not the cordless one, that didn;t do anything to the bolt, I actually cooked the proper drill that would make holes into concrete wall, but couldn't remove stupid bolt...
Nothing worked. I do have got the right bit for those smaller bolts, but it just wouldn't move. Managed to remove only one of them, which caused that my doors won't close anymore, but since I couldn't get the other bolts out and run out of ideas on which power tools to use, I gave up on them for now.
Luckily I run out of cutting discs for my angle grinder too, otherwise you would have seen new picture manual on HOW TO remove the sliding doors by cutting it into pieces...
What else does "underseal the welds" mean? I bought the "untirust" filler - it says on the tin it prevents the rust, hmmm
