RHS middle section
The driver's door is in good condition apart from a
shallow crease along the length of the lower section. When
I'm ready to paint Cynthia, I'll (bravely) knock out the
deepest bit of the crease using a hammer and dolly before
applying a thin layer of filler (eg Plastic Padding) or
cellulose putty. Two points are worth noting about
filler:
- It is designed to be applied on bare metal and is
more likely to separate from a painted surface.
- It is porous and absorbs water. Paint filler as soon
as possible after it has set and been finished. Most
primer paints are also porous.
The door tread plate has rusted through in a few places,
a fairly common problem. Spot welds (at the side of the
vertical flange to which the door draught seal attaches)
were ground out before applying hammer and chisel to remove
the old tread plate. A small of the floor section below the
tread plate needs patching.
A
replacement tread plate (left) was obtained from John
Kipping. As you'd expect, for such a simple section, it is
an accurate match for the original. The replacement plate
will be plated on the underside to prevent future rust and
it will be plug welded in place.
There are one or two small perforations in the outer
cosmetic sill panels. These have been stored in my spare
bedroom for several years and they'll be one of the last
things to repair during this restoration.
The structural outer side rail is not an original part
and is slightly shorter than the proper part and lacks the
strengthening gussets. This part will be replaced after the
rear outrigger has been replaced. The centre and front
outriggers both require patching at their outer ends where
they join the outer side rail.
RHS rear suspension, drive shaft and brakes
As with the front corner, I chose to strip the mechanical
components from the rear corner to improve access for the
welding work. I daresay you only need to partially dismantle
the suspension to gain access to the outrigger but it is a
tricky enough job without making things harder.
The
only difficult part of rear suspension disassembly was
unfastening the bolts on the universal joint flange. Good
quality spanners and generous use of penetrating oil
(PlusGas) made all the difference.
The brake cylinder was again removed and put in dry
storage. The hand brake had always a problem at MOT time,
even after the mechanical linkage had been correctly
adjusted and lubricated. I suspect that the brake drum is
worn undersize or that the brake shoes are "wrong".
I haven't checked the universal joint for play yet. I
have a couple of spares handy if they're worn. The wheel
bearings have fortunately never shown any sign of play. If I
do detect a problem, I'll send them off to a specialist with
the proper tools to disassemble the hub
All of the radius arm and shock absorber bushes are in
surprisingly good condition and will be re-used. The
transverse leaf spring has been left in place and only
requires a little cleaning.
