Get rid of those last bits of rot

The spine of the frame isnt in too bad condition except for one or two places where the rust has found its way all the way through to the outside world (I wonder how long this process actually takes?) - So a good 3 or 4 hours work saw me cut out the, make new and weld back in.
My sheet metal clamps worked wonders here to hold the bits in place while I welded, but the magnets havent helped at all really - the magnetic field plays havoc with the welding arc - its impossible to TIG weld in close proximity to magnets.

I show the inside of the weld here in the last picture for no other reason but to prove to myself and perhaps an MOT inspector that the penetration on the welds is pretty good :-)
