This is ' the plywood Kings ' 1964 effort . He'd been in the Airforce , running the Yacht Squadron ,
and purloining the cable conduits out of the Mk 16 Spitfire now in the Auckland War Memorial; Musem
so that ' those Larikins ' couldnt fly the thing and wreck it , back in 48 ,As they were a bit careless
with their aeroplanes at times.
This was built with ' Aerolite ' glue , and is still going strong .
Theres many types of ply . I just got a piece of 1/32 , , 0.8 mm Birch Ply . ( Made in China )
Timbers regarded as having about the same strength / Weight as steel, but is bulkier.
The next Yak wing I do may well be ALL ply , bar spruce spars etc and fittings.
The old mans idea was it needs about 2 percent curveature to provide strength
" Otherwise it'll just flop around , it wont have any strength.Havnt you ever seen the bonnet of a car "
As in a flat sheet hasnt got a lot of resistance.He mustve been right, the big 73 Chrysler Hardtops
bonnet with just the perimiter frame left to lighten it , flattened off peceptably after a doseof high speed
touring.
A tapered wing is going to use its benefits most advatageously .

William Towns , the Aston Martin -Lagonda Coach work designer produced large ' Mini Moke ' like
V-12 Jag powered 140 mph TIMBER chassis / bodied vehicals.
Marcos produced fibreglass , Timber Chassised cars.
Eventually they changed to steel chassis, as niether
boat builders or panel baters would touch accident repairs.
Marcos was Marsh and Costin , Costin , an Aerodynamisist
did LeMans Lister Jaguar and Maserati V-8 coachwork design.
And pedeseded Lotus in that concept aerodynamically.
Zagato who did the bodywork for the Maseratti to his design
didnt realise the importance of the placement of the inlets and
outlets.So at leMan's a large hole was chopped in it to avoid
the driver assphixiateing as well as roasting.Its the details that
count .
Designed to make use of the Ellement , such as the skinning for
the front of a Beringer Wing, or Namely the structure itself , it
" Has Promise ".
