Hi Randy and all

I was on Bee-L when Mr Imirie was here but never could figure out  
what an Imirie shim was.  However, if it is a rim similar to those  
recommended by Miteaway then I have been using them for years.  I put  
them on in the autumn when I start baggie feeding and treatments.   
They come off in the spring after feeding and treatments.  My inner  
covers have an entrance cut into the edge on one side but no other  
openings.  The entrance side down in the winter then I flip the inner  
cover over to close the upper entrance in the summer.
