The thin sheet of plastic material that comes with the Paynes Poly Hive as the standard crownboard just sits on the top of the frames. Whilst there are those that like this arrangement (and I'm not here to start an argument about top or bottom bee space) I prefer top bee space. Unfortunately, the only way that this can be easily achieved in these hives is to leave the metal frame runners out - which means the frames just sit on the polystyrene ledge - not ideal.
I've made a number of clear polycarbonate crown boards out of 6mm and 8mm polycarbonate and they are really good - but I hate wasting things nearly as much as I detest spending money - so, today, I made a timber frame for the thin sheet of plastic. Just softwood cut to about 8mm x 15mm and glued onto the edge of the sheet using CA glue (and some activator to save a little time as it gives an almost instant 'grab').
I thought originally that it might need some additional strips of wood across the centre to support the flimsy sheet but it's turned out remarkably rigid with just the frame round the edge, so I didn't bother. The hive roof still sits comfortably on top and it cost next to nothing to make apart from a bit of glue and some waste scraps of timber.
Better than the original (IMO), although it won't be sufficiently robust to cut a feed hole and support a feeder - but I've got thicker polycarbonate CB's that will do that.
Works for me .. and in Dusty's words - You can never have too many crownboards.
