The 10 m Alternegy fibreglass blades which should be tried out
for the first time, delayed in materialising. Therefore a new project
featuring wooden blades, supported by the Ministry of Trade &
Industry, was initiated in 1982. These blades were produced in a
new workshop hall which in 1983 became part of the Folkecenter.

Production in 1982 at the Folkecenter (above) and transport
(below) of wooden blades for the 90 kW Folkecenter-designed
Blacksmith's windmill for Rudbjerg, Lolland.
The blades were made from solid, laminated spruce, based
on experience from a NIVE experiment in Alaska in 1980, and
followed by a number of experimental blades, that is, some 6.5 m
for the experimental windmill of Danebod Folk High School, under
the leadership of René Karottki. Many expected that solid wooden
blades would be far too heavy, but in actual fact they were able to
compete with the rather heavy fibreglass blades of that period.
