Unfortunately most of Cynthia's restoration will have to
take place outdoors on the driveway. This is not too much of
a problem because her bodywork and chassis are good enough
to avoid a body off restoration; the main disadvantage,
aside from the rain, will be wind which can make MIG welding
a little tricky.
I expect to do at least 90% of the work myself -- the
Herald is the ultimate Meccano kit car and I'm confident
there won't be too many unexpected problems that will send
me off to the specialists. For parts, I anticipate dealing
with most of the well known dealers. Alas, I haven't seen
any Heralds in local scrap yards because I require one or
two bits that are no longer easily available.
Each of the Restoration pages describes the jobs tackled
on a region of the car. This page, for example, deals with
work carried out on Cynthia's right hand front corner. The
accompanying photos are a pretty good guide to places where
a typical Herald might rot.
RHS front corner
I decided to strip the front suspension to make more room
for the welding work on the front wing. This is
straightforward stuff and described well in the various
repair manuals.
The MOT inspector had already advised me that the
trunnion was worn; fortunately, the threads on the upright
itself look good and the replacement trunnion is a tight
fit. The play observed by the MOT inspector was probably
being exaggerated by wear in the top ball joint which will
also be replaced. The wheel bearings are known to be good as
they are only a few thousand miles old.
I left the wishbones on the chassis. The inner bushes
were in good condition and I don't replace parts for the
sake of it. Polyurethane (rather than rubber) bushes are
available at reasonable cost and if I were intending to
uprate the engine and brakes, I would fit these.
The shock absorber bushes were badly worn however. The
load on the inner (top) and outer (lower) bushes is much
higher than on the wishbone bushes so I chose to replace
them. The spring must be removed using a compressor to
replace the top shock absorber bush. I did the job safely
with a hook type compressor, but the job would have been a
lot easier using a tool like the Churchill one described in
the factory manual.
The track rod ends had worn out again after just a few
thousand miles -- these had been replaced as part of a
pre-MOT service a couple of years ago. Some cheap
replacements have been purchased but they appear to be the
same brand as the worn ones. I've made a note to look for
some genuine Stanpart rod ends to fit when the cheap ones
fail.
I've never been aware of any problems with the steering
rack but I removed and cleaned it anyway. With the gaiters
removed, there was no play on the inner ball joints or
elsewhere so I just re-assembled and painted the rack. The
rack mounts (rubber type) also looked good and will be
re-used. If I've made a mistake, they're very
straightforward to replace. Similarly the anti-roll bar was
removed and repainted, with the intention of re-using the
mounting bushes.
The brake caliper was removed and placed in dry storage.
The seals were replaced after I purchased Cynthia but the
cylinders and pistons are prone to rust, especially when not
used. I'll look at the front brakes again as one of the
final points of the restoration. The flexible brake hoses
will be replaced at this time (new copper brake pipes are
already fitted). It's impossible to determine the condition
of a hose as they tend to fail from the inside and these
hoses are quite possibly the originals.
RHS front wing repair
The front right hand wing was in very poor shape all
along its lower edge. Repair sections are available but
several Herald enthusiasts advised me that replacing the
entire wing makes more sense. The photos below show the
general condition of the wing.

This
photo shows the rusty lip on the right hand wing.
The wheel arch panel and the outer wing are almost
completely separated.

A
view of the wing near the bonnet catch. This area
is just starting to rust through indicating that
the whole wing should be replaced.
|
The
area around the sidelight/indicator cluster is in
good condition. The reinforcement D plate behind
the light cluster is just starting to rust
through.

A
D shaped reinforcement plate attaches between the front
wing, wheel arch and front panel. A replacement (right) was
purchased from John Kipping and is a perfect match for the
original. The steel is a slightly thicker gauge, I suspect.
It's accuracy will be very useful in correctly aligning the
outer front wing panel.
The
two main panels -- outer wing and outer wheel arch -- were
purchased from T D Fitchett. Compared with the original, the
outer wing was a good match dimensionally although the
flange below the headlamp was turned the wrong way. I
understand that this is common for replacement 13/60
wings.
Unfortunately the outer wheel arch panel looks to
be a pretty hopeless fit. The flange that is attached to the
inner wheel arch section is the right curvature and length
but it does not look as though it will butt with the
reinforcement plate without some work. The lip that joins to
the outer wing is hopelessly wrong and a lot of cutting and
reforming will be required to join the two panels.
Stage one -- outer wing removal: The wing is held in
place by welds along a flange under the bonnet panel and
along the edge of the front panel (adjacent to the
headlamp). In theory, the front wing is also joined at the
lower lip to the outer wheel arch, but, in Cynthia's case,
this section has rusted away. The old welds were ground out
using an angle grinder -- not a particularly pleasant or
quick job. The bonnet locator plate (at the top rear edge of
the wing) was then removed from the old panel for re-use.
Fortunately, the plate is in good condition as I am not
aware of anyone who is able to supply one new.
Stage two -- outer wheel arch removal: The wheel arch is
in two sections and I chose to replace the outer section
entirely. Again it was removed by grinding through the welds
along the flange joining the two sections. It would be very
difficult to remove the outer wheel arch section without
first removing the front wing.
|
The two photos show the process of removing the
front wing. In the left hand picture, the bonnet
locator plate and a bit of wing are still attached
to the bonnet flange. On the right, both the outer
wing and outer wheel arch panel are shown to have
been removed.

Stage three -- reinforcement plate removal: The plate is
vulnerable to rust, althought the one I removed wasn't in
bad shape. Removal was fiddly but I managed not to damage
any of the adjacent panels.
Stage four (to be completed!) -- trial fit the
reinforcement plate and outer wing: The replacement front
wing needs some gentle reforming and trimming to fit. Holes
will be pierced or drilled along the flanges and welded in
place. I'm not sure whether to use my MIG welder or my aging
stick arc welder. I will definitely need to use the carbon
arc brazing attachment on my arc welder for some fine
touches on outer wing.
Stage five ** -- fit new wheel arch panel
