Drawings of Rational, Top Bee Space
Bee Hive, Component Parts
The "Rational" hive was designed by Dave Cushman in the
1980 and 1990s. It is essentially a top bee space (tbs) National with other
parts modified. Compatibility with tbs National
equipment is assured as the brood box and supers were tbs National.
I suspect the Rational hive may have been included in the catalogue of Apex Enterprises, but I doubt if it sold well. I have certainly never seen any.
Cushman was a thoughtful man and I'm sure he spent many hours
developing these modifications, but they were non-standard and for that
reason not attractive to a purchaser. Dave felt that each item offered
some benefit over more conventional designs, either in
terms of ease of assembly, durability, function or productivity.
of the parts were made of cheaper materials than those used by most
manufacturers at the time, these being pine and plywood/hardboard instead of prime quality cedar.
am continuing to display this page, but I am unable to do anything
about the buttons that don't work, as I can't find any drawings. There
are some good ideas on those that do work and I hope they will prove
