The term "unified" has been used in other contexts as well as this one.
A creation of Richard Alabone, (the Beesy Frame man),
essentially a standard 356mm (14") wide frame, but deep enough,
(360mm), to fit inside a box formed by stacking an empty shallow super
on top of an empty brood box.
Wiring Holes are 1.5 mm Dia. Tolerances are + 0.1mm
Material... Most softwoods are suitable.
The Drawing below is for EXTRA DEEP 14" x 12" SIDE BARS...
Just use 360 mm as the length instead of 304 mm. The version that
Richard produces is made using his
plastic frame corners, but
the principle can be utilised using "Standard" woodworking methods.
There are various ways of implementing this type of frame as
there is no commercially produced foundation, readily available to fit
it.
When assembled it looks like this:-
The left hand sketch shows two panels (A & B) A can be
either worker or drone based foundation, whereas B should be worker
sized. The bar across the join is formed by two Manley type bottom
bars rebated into the sidebars.
The right hand sketch shows a possible use of full sheets of
Composite Foundation.
I have not tried this unified system for myself, but trials
were conducted at "Brooksby Bee Yard" during 1998 & 1999. And I will
attempt to obtain the details from those involved.
