first i striped the paint and seem sealer back an removed all of the soft bits.
which reveiled this lovly gaping gash in the arch.
in order to get a good weld it is important to clean the area of as much rust as posible and all oil, paint and water its also a good idea to go looking for bits that are a bit too thin to work with at this point.
the weapon of choice for this is normaly the angle grinder, it is posible to use a wire brush or chisel though.
and this is the result.
The next job is to find some good metal to fabricate plates out of, for this i used some left over 1mm steel from the inner wing of the ka.
this has to be cleaned like the rest of the area has been and cut to size.
then its time to fire up the welder. (i will expand on this after dinner.)
the welds and general area need to be ground down and treated with a good corosion prevention. i know i could have ground the welds down a lot more and left it looking almost factory but i thought as it was out of sight and the strenght was more important than looks id leave it standing a little proud.
when the corosion prevention has dryed finish off with a nice coat of paint.
This being the new jacking point and chassis rail on my Manta 
True, but that hole is still a baby compared to what i've had to fix
