Body Restoration
The key to our Body Restorations are
our jigs and fixtures. Our main fixture
emulates the MGA's frame, except our tolerances are much tighter
than we've seen on frames. It's common and acceptable for frames
to have 1/4" or more variance on some dimensions (in fact,
the factory manual lists some tolerances as +-1/4"). We built
our jigs and fixtures to 1/32" tolerances.
We start a body restoration with measurements of the data we've
found to be key. These measurements set a baseline and give us an
idea of how good the body is to start with.
Following this, all paint and rust is stripped from the body. Most
of the stripping is done by a local sandblasting service. mount
the body on one of our rotisseries so
that the sandblaster has good access and won't "tweak"
the body while rolling it over.
There are parts of the bodies we hand strip, mainly the front and
rear upper cowls. We hand strip the external parts of doors and
bonnets, and strip the backsides ourselves using a combination of
careful, protected sandblasting and hand stripping.
The main body tub is then mounted to the jig and repairs are made
to the front and rear tubs before sills are reinstalled.
One the tubs are repaired, we install the sill/pillar assemblies
using our spot welder.

After the main body
tub is finished, we hang the doors and fenders, making appropriate
repairs and fit-ups along the way. Most patch panels are butt-welded
using the TIG welding process.
As the fender and
door repairs are completed, we ensure even 3/16 " gaps appear
around all panels. We latch and test doors, bonnet, and boot lid.
All internal panels are installed, as well as finishing strips so
that there will be no surprises later on. Finally, we make sure
that no panels are "stressed" so that the restoration
will maintain long-term accuracy and fit.
While our jig's accuracy
continues to prove itself, we always test-fit the body back to the
chassis before the car leaves the shop. At this point, any final
details are addressed and all measurements are re-taken and compared
to the originals.
Once we've completed
our work, the car will go to a body shop for final smoothing and
painting. While the body will have all critical dimensions and gaps
fitted correctly, it's common for a car to get a skim coat of body
filler over most of its panels prior to painting. Thanks to the
quality of modern fillers, there is no need for concern about this
method of final finishing.
