I've tried putting bees and comb into frames - - and it didn't work very well. The comb simply never got 'attached' to the frames. The only difference was my bees had moved into a seldom used shed and built from the rafters. We had combs that exteded downward for THREE FEET!! I would suggest, after you have the hive isolated that you stand that section on the ground. Place a piece of plywood with a large hole in the center on top of that section - and a regular hive body on top of the log/plywood. The bees will 'move up' into the hive body, eventually vacating the log. At this point the log can be disposed of. Keep building on top of the body. My $.02 worth.
