A hammer, chisel & angle grinder, or it you have lots of time drill all the
spot welds out & use a hammer & chisel to ease it off, to replace either buy
a spot welder or drill lots of holes & plug them on, you will still have to
seam weld in places, the book mini restoration by Lindsay Porter is a good
reference,

Hi Martin

In addition to Steve's suggestions there are also some useful responses
if you search inside this newsgroup under 'wings'.  I found some of
them helpful when I started.

I'd start off by saying remove the old panels with care. If you hack
them off like an old pro you may struggle to find something to fix them
to. Plan ahead. Take pictures before you start. Your memory will desert
you just when you need it. Its also about ensuring all the panels
around align before you fully weld. Use the bonnet (for the wings) and
doors (for the A panels, sills etc.) and use lots of clamps.

Measure twice weld once. Good penetrative welds, not ridges of weld
sitting on the surface.

Someone also said whatever tinworm you can see, there's a whole lot
more waiting for you behind that panel. They must have seen my Mini
because they were spot on...

Finally, wear a full face mask when grinding and wire brushing with the
angle grinder. When (not if) an grinder decides to leave your hands on
full speed there's no saying where it will end up after it has bounced.
In my case it hit my nose. Some say I'm much better looking now, but I
was lucky.

Hope this helps
