Re: Frames without bottom bars
I think in stacked boxes a bottom bar on the frames is a must. The bees might still build burr comb between a bottom bar and the top bar under it, but you can still remove the box without tearing comb off of the frame.

If you have access to a table saw the quickest and cheapest fix might be to cut up some bottom bars, trim the bottom of the comb to the correct length, and gently nail bottom bars onto the frames, driving the nails through the side bar into the bottom bars.
To initially get the boxes apart without tearing up too much comb try using a length of strong wire to slice through the attached comb. Start at one end and with both hands run the wire between the boxes in a sawing motion across the whole box. The top box should come off much easier after the comb has been sliced with the wire.
