Yesterday i set about having a proper look at my sills and after some heavy poking decided that maybe i should consider replacing the sills with box section.
Its only really one side at the back that has led me to consider this, the other side is actually not too bad and could be easily plated (small hole in the outer sill at rear).
So i've a few questions to help my decision process (i've seen makitfits posts but cutting the sills off means no going back - so want to be sure).
Here goes - could i simply cut the curved outer (and middle) sill in a straight line say 1" below the bottom of the door shut line, then cut along the bottom of the sills at the vertical line (Leave the vertical bit intact where the body mounts are all welded to).
Then simply insert box section into the bit i just cut out and weld along top and bottom (plus enclose the ends)?
Also, do i go all the way along including the small front section?
What do i do with the middle bit of the sill (i assume that runs all the way along front to back)?
I know for the mot it needs to be a continuous weld, but are there any other issues in this respect, i.e. how thick would the box section need to be etc.
I've drawn a very basic diagram to try to visualise.
Am i being to simplistic? I've never cut a sill off before so not 100% sure what i will find underneath.
Or is this all wrong and i should do something else?
