Alvis Bonnet repairs part 2

The bonnet has been cut down by an inch and a half all the way across the back edge, this needs to be replaced. So it's the usual procedure, tack weld the piece first the seam weld using TIG and about 75amps AC.





Welded inside and out.

This first section was planished flat file and sanded till smooth.
Then on with the next section to match the first.
The sides of the bonnet still had original paint.
This paint stripper works fast and does the job well.



A quick video to show the results.



As per the previous repairs make a patch to fit exactly, tack it first then fully weld it in place.

Lots of clamps and a backing strip.


Finished in the normal way.



The other side was treated in the same way.

The Aluminium trim strip also needs to be extended.
This is not a swage line, it is a solid piece of Aluminium riveted in place.
A small section was cut with a hacksaw length ways along a one inch bar of Aluminium to make a D shaped section about 5mm thick in the centre.
The piece was welded to the end of the original strip but only in the middle, this was to ensure that no distorion was introduced into the finished panel, which would be more difficult to planish out now that the strip was in place. A small amount of body filler will hide the joint before paint.
Then a solid Aluminium rivet was used to secure it into the panel.





The finished repairs which took around 16 hrs.
