The drawing on this page and the other CDB hive part pages
is of similar flavour and style to the original, draughtsman produced
drawing, whilst at the same time improving the clarity of presentation.
Imperial dimensions are used because the equipment was
designed that way and the limits and fits were sorted out according to
the Imperial timber dimensions. Metrication has not been attempted
as to do so would require knowledge of the original designer's
calculations (which are not available).
This view is very similar to the front elevation. The
ventilation hole is shown with perforated zinc covering it, but many
examples have been found with
double cone escapes
like those that are shown on the front elevation.
The roof profile, Shown below, of many home constructed CDB
hives was a simple "A" shape, constructed using narrow slats of random
width butted together. These slats being covered with roofing felt or
painted canvas forming a waterproof outer skin. Zinc sheeting and in
some cases lead flashing have also been used as waterproof coverings.
