Imirie Shims (invented by George Imirie) are wood frames with the outside
dimensions of a hive body, and about 3/4 inch tall. A 3/8" by 2" notch is
cut into one of the narrow sides.
Imirie Shims are used to provide an additional hive entrance during the
honeyflow, and during requeening by the "nuc" method. A more detailed
description of how the Imirie Shim is used is in this year's Brushy Mountain
catalog, and I believe somebody posted a copy of the description on BEE-L
last night.
George does not have a computer, but I will be glad to take any comments to
him if you wish, and will post his replies.
