So onto the next bit of welding.Well felt more like archaeology actually.
Well there is the gribbly bit on the sill that I didn't like the look of, so I attacked it with a wire brush.
Strangely it opened a portal to another dimension. A Land of filth and rust and decay...oh and pain and welding.
It was so hideously deformed that I had no idea of its original shape. Had to order a panel from Schofields to try and get the shape back.
I started with a small exploratory incision....just remove the rot. Oh
So er thats sposed to be the inner sill then and er is that C post supposed to connect up ?
So open it up a little further..
Cut out the bit I can get to, and guess what our journey continues - deeper into the lost realm of Syncro sills...
So this time a hole into end of the rear chassis arm, and a whole through the patch just outside it, hmmm patch over rust and capillary rusting grrrrrr
Borrow the good ladies vacuum cleaner and hoover out all the missing matter from the universe ? Maybe this is why our roads need resurfacing, its all in my sill.
My exploration continues, I break through oh, its a plug into the wheel arch, well it was a plug, now its a plug and a pile of powdered metal. Lets go the other way to where the C post used to be.....
NO actually lets not, lest weld this bit back up and make it solid again before the whole wheel and suspension arm drops off.
So you think you have found solid metal eh ? Well I cant get the grinder in to remove any more, so its file and chisel then weld and burn....
chuck some vactan in for good measure, but really its just a time bomb. New inner and outer sills sooner or later. But I have to get it solid to move and drive it even. So no choice at this point its not pretty, but its solid. Just the best I can do
and the next layer working my way back out from the horrors

Sealing it back up behind me so as not to let the evil spread...
Now that C post.... I'll just errr open it up a bit more ? Errr well I'll try and keep it to the sill, so that when it gets replaced...
Lots of hacking again, grinding, filing, but again not enough room to get in there. The rust doesn't appear to extend further forward ? But this is like restoring an old house ! Where do you stop ? Were getting a bit out of my league now. How much does it cost for a pro to replace the sills and get it looking pretty ?
At this point I start trawling 80-90 for photos of what the Cpost should look like. Found some remarkable thread on DIY inner and outer sill replacement, with lost of support from Metal Mickey. Wow that is quite a task. Might need a garage, or a roof atleast or maybe a professional...
Anyway start building it back up layer by layer.
Hmmm I think it was Silver Bullet posted pics of a nice sill end/jacking point rebuild he di. Looked lovely and clean and really easy...
So I guess the C post is supposed to look something like this ?
Spay it with gucci weld through galvanising spray, yeah that makes me fell better. Well it might help ? A bit.
So time to hide it all wit that nice replacement panel so it looks pretty and I don't have nightmares about what lies beneath.
The plan was to try and avoid loosing the wheelarch to rear wing seam line. The panel is all one piece, so some creative cutting is required. And err welding back together cos i got it wrong. Ooops.
Spot, Spot, move spot repeat ad nausium or untill you run out of welding gas. I ran out of welding gas...
So I still have to finish it between downpours. gotta be done by Monday cos I'm off on another adventure
Cheers
