A little update for you chaps..
The big patches have been fully welded up.
And a small hole at the front got the same treatment, I just need to trim it to size.
I also found another small hole on the right side of the seat base..
Which turned into a bigger hole.
For some reason I forgot to take any photo's of that patch being welded on, so here's one of the big patches marked out for trimming to size.
And that chaps is the seat pan just about done.. as ever there is a little grinding of welds inside to be done, but that's all.
Sorry this one's a bit blurred!
