Wings are the most distinctive and dramatic Morgan 4-wheeler
feature. Their shape has brought the Works from 1936 to 2006
intact. No one will argue that without them, the company
would have Peter'ed out (pun!) more than five decades ago.
As in any project, opinions/experience is gathered, options
sought and therefore knowledge levels increase. This new
stuff all settles in and compliments one's own experience.
In a nutshell, speaking with the wing makers and their
repairers in the last few weeks have given me a deeper
perspective on these four Morgan signature parts.
I do not suggest that I am correct in my musings, but for what they're worth....
1. VINTAGE WING & RADIATOR (VW&R) Steel
Wings
http://www.vintagewingsandradiators.co.uk/pages/home.html
This is the original supplier of Morgan wings until the Superforms (reviewed below.)
Pros: My opinion of steel wings has risen. They are impact
resistant, protect the paint finish and if properly
prepared, are slow to rust. After our accident, I took
my old front wings (18 years), had them sandblasted and we
could find no signs of rust. I primed them to protect
them. (Shiny mild steel rusts in hours). and they are now in use on another
car.
When they do rust, one easily can weld in a patch.
They are inexpensive.
All wing styles from any eras can be made.
Cons: They can rust. As well, they come poorly made with
a wide variance in dimensions, fit and preparation time. They
crack at the wing light and corrode at their stays/braces
if proper measures are not taken. However, all of this is repairable.
2. VW&R Aluminum Wings
Pros: Lighter than steel..but much so less than has been
reported. Corrosion resistant outside of the infamous edge.
Can be welded with a bit of care.
They are inexpensive.
If one starts from scratch, (no pun) and prepares them very carefully (as described below). They can last many years. However, that type of prep cost puts them in the range of Superform wings without Superform advantages.
Cons:
a. The way the steel wire is installed in the edge, coupled with the Factory prep normally pre-determines the death of these wings. Unless they are redone before it is too late and very careful steps are taken to completely seal the wire from moisture, corrosion MUST occur. The combination of steel, aluminum, water and the vagabond electrical charge all cars have throughout spells doom for these wings as, to date, when the edge goes, so does the wing.
In some countries and climates, namely the UK or the North
American northwest coast, one can only retard the process as the only way
to stop the electrolytic reaction is to open the edge, remove the steel
wire, remove/repair the corrosion, and replace the wire with something
else of sunk in non-reactive sealant, then the edge must be refolded, a
covering flange welded over the seam and the tabs replaced.
b. Their soft alloy cannot protect the surface paint. Star fractures are common. Welding extra plates on the underside has not proved to help. The best solution seems to be one I have seen developed independently on both sides of the Atlantic. That is an impact coating, (which can be covered with 2 pack black) and glued rubber padding in the key areas.
c. Their soft alloy is prone to crack. Spot/fog lights, stays and braces wing lights. It is in these areas that extra plates can help.. not with the star fracturing but the stress cracking.
d. Like the VW&R steel wings, they are awkwardly made and inconsistently finished..adding to the costs of prep.
One wonders why VW&R never improved the product in so many years. I suspect liability issues. You are safer legally in simply reproducing a vintage part than newly modifying it.
The other reason was cost. When the management of the
Works changed ten years ago, there was a demand to the suppliers to lower
prices. Many complied. However, a demand for a 10-15% discounts is not
a good way to encourage product improvement. On the other hand, the resultant
confrontation was definitely an incentive for the Superform inquiries.
3. SUPERFORM Aluminum Wings
Pros: Made from an extremely hard aluminum alloy that has proven itself to be VERY resistant to star fracturing. I have been traveling 4 miles of gravel road at speed almost each day during the season for 3 years without a fracture yet.
Very easy to weld.
They arrive (almost) perfect. So little prep or putty
is necessary that their much higher price is mitigated by a saving of £350-400
per set in saved labor.
Instead of a steel stiffening wire at the edge, they
employ a grooved aluminum molding that is bonded on. Ergo no corrosion
anywhere, assuming you do not prejudice that with a steel to metal add-on
and a bit of care is taken with the fittings through the wings (easy to
do).
They have a plate welded on the underside at the wing lights, offering greater protection there for cracking. If the pressure is spread with the use of a large washer, that is sufficient to prevent spot/fog lamps from cracking the wings.
Not much need for wing protect underneath, save a quick
coat of black impact paint, more to cover the Factory overspray
than anything else.
Cons: There is a limited choice in styles. With the Superform
process, each wing style requires a very expensive
mold and that has limited the choices.
The delivery time is long.
They are very expensive. More than double the price of the VW&Rs (but then there is the large prep work saving). Only purchasable through the Morgan Factory or their Agents.
They require special paint preparation or bubbling can occur.
