I cut out the rotten part of the arch (I bought a whole new nsf arch panel but it was like a tin can and couldn't bring myself to replace the factory arch with it)
So I ended up making up the rotten piece out of 1.5mm sheet (using two pairs of molegrips, a brick and a lump hammer!)
Once I cut it off I noticed a hole in the inner arch right through to the jacking point so I patched that aswell (didn't stop to take a picture sadly)
Then once done I welded the repair patch onto the arch (the lip is from the original arch and I used this to get the profile right. I drilled a few 8mm holes in the lip to weld it to the A post (or is it the B post?)
then flatted it off with a flap disc on the grinder and gave it a coat of grey primer
For my second attempt at welding i am pretty proud of it.
Tomorrow I am off to pick up my bottle of argoshield light from BOC then on with the seatbelt mount repair.
I will post more pictures as the restoration progresses
