Harry Cloake of New Zealand is the originator of the
method that this item was devised for.
I made mine from a framed Herzog
type queen excluder. The table of parts below is for parts required
in addition to an existing excluder.
If the slide is not fitted then the entrance aperture will
take an entrance block 421 mm
x 21 mm x 21 mm. The outer edge of the slide is built up to form
a reduced entrance when it is in place.
The Grain should run along the longest dimension of any part.
Cutting of parts (all dimensions in mm).

This item is utilised in
Method 2
increase.
Scale = 1 pixel per mm.
petroleum jelly
should be used on the upper and lower surfaces of the
rim and the grooves that the slide runs in.
linseed oil is
used on the external and internal vertical surfaces.
There is a second component to this item... The slide is
illustrated below left outlined in red, with the outer portion
"ghosted" in grey/white.
The slide should have its outer edges treated with petroleum
jelly and the major surfaces coated with linseed oil.

When the slide is inserted the access of the bees in
the bottom box is cut off, but the upper box bees can still come
and go from the same entrance position that they are used to.
The slide should be shorter, by one bee space, than the
space it slides into. For practical reasons dead bees and debris may
be dislodged when the slide is inserted. The space allows this debris
to be pushed along by the back edge of the slide, but as it is
slightly shorter it does not cause any jamming. The slide must still
overlap the excluder woodwork by at least one bee space so as to
ensure total isolation when the slide is in the closed position.
The slide locates its depth of penetration by the shoulders of
the runners on the back edge of the entrance reducer.

The only disadvantage to this piece of equipment is that
it spends 70% - 90% of its life in storage.
Generous application of petroleum jelly will enable easy
cleaning of the bracecomb that will form when this item is used,
continously, for several weeks.
The entrance notch should be 100 mm - 125 mm wide by 8 mm
or 9 mm deep,
