I watch your project with great interest as you are doing work I will have to do myself at some point I do have a quick question though. at the rear end of the sill just inside the wheelarch there is a small round hole with a bung in. On one side of my van, the area just around the bung has gone rusty because the cavity behind it fills up with water when to has been raining. I can try to show with some pictures:

Firstly from one of your earlier pictures, this is the area. The red line is where the outer skin profile would be and the blue circle is where the circular hole and plastic bung are. It is the cavity behind this that fills with water:



This is the same area on my van:


The bung is in place at the bottom.

I cannot work out what the construction is of the area and cannot see how water is getting in between the outer skin and the internal web. I assume it must be coming down from the window seal somehow? So far apart from the very small amount of rust at the end, there is no damage as the inner area seems well protected. The water that drained out was clear with no signs of rust in it. I just wondered, having taken this area apart, if you might be able to shed some light on where this water might be getting in?

Keynsham1,,, I don't remember any bungs on mine I think that whole area had rotted away, the inner wheel arch repair panel I have installed does have a hole in it in the area you highlighted blue.
As for water ingress, My side window seal was leaking and this can get directly into the area around the pillar and inner wheel arch. Possible it could be that if you have water present.
My inner skin and sliding track had also rotted out because of this water issue.

If you were able to remove the interior panels (carpeted plywood etc...) you can see into the void, I would then use a hosepipe sprayed onto the window to try and determine if the water is coming in through the window or not.

Jrt,,,. Thanks, hopefully it will be of use to other forum users.

Thanks for your reply. I think however I may have solved my own problem! I had a look at my van after my post and realised that my fresh water filler is directly above the area! So I removed it and I can see down into the gap




This is looking down into the cavity from the water filler hole. You can see the bung on the right. I think the water was getting in either when I was filling the tank, or around the sealant of the water filler pipe housing. Luckily it hasn't caused any serious damage!
It will need properly sorting when the weather gets better but for now it is going to be a clean up, a good soaking in rust eater and something to protect the wheel arch area. Roll on summer when I can do a proper repair!

offside sill welding and floor removal

Today was some welding and much cutty cutty...

Started by welding in the bottom of the B pillar to the sill, the bottom lip of B pillar was rusted away so all new metal welded in to create the lip.



Once the sill was nice and solid I decided to rip the floor out, there is just too many holes to bother repairing it.. the other issue was that where the cross members attached to the floor lots of rust had grown in all the seams.



With the floor removed I can see the 2 main cross members have a liberal coating of rust on them,, nothing too deep so a good cleanup should get them back to a good condition.
I'll paint them inside before I put the new floor down while I have the chance.

I am also going replace the other small folded sections as they are simple enough to make so it is not worth the effort of cleaning the existing ones up.
I might replace the centre support which the fuel tank hangers slot into, the panel is available and not too much, while it's stripped this far seems daft not to replace with fresh metal.. the existing one is not too bad, but is quite crusty at the spot welded flanges which attach is to the main cross members.

As for floor panels I have plenty of 2mm steel sheet so while this is thicker than needed it will make the floor considerably stiffer, I'm not sure whether to bother with the corrugations due to the extra thickness, maybe I'll just do some beadrolling.

More floor crossmember work

So this evening I took lots of measurements and then cutout all the centre members, all appear to be non-structural so no worries removing them.

Will make all new parts to replace soon.



Also something I wanted point out is that the floor before I removed had a massive dent in it, which by chance was over one of the main structural crossmembers, whatever was dropped must have been sodding heavy as it managed to deform not only the floorskin but also the cross member. I'm struggling to even think what could have been dropped to do such damage.



That's all for today, some measuring up and panel making next.

Excellent work, the bead roller mod is an brilliant ideal

Well impressed , the side window repair is just what I'm looking at doing later this year .
The prospect of having to buy the full side replacement panel has been putting me off.
Great work, look forward to seeing more.
