Just wondering if there's any amongst us using these? I have a bag full of them and fancied giving them a go. To that end I made up a frame with two bars with holes in them to take the prongs. Does anyone know how easy these are to remove once replete with wax and sealed queen cell - I'm thinking a hive tool might be necessary which might lead to damaged queen cells in my klutzy hands. The type I mean are those with the wide base and the oval shaped prong which grips when you turn them on to the oval cross section. Or do I need to table saw a groove the length of the cell bar rather than use individual holes?
