We recently cut down a large tree in our backyard. I have some large pieces of trunk laying around. My question is how do I cut out the insides of a trunk to make it hollow from inside so as to resemble a natural bee tree? I have variable lengths 1ft to 10 feet and 1 feet wide to almost 2.5 feet wide.
p.s I know its illegal to keep bees in non removable frame hives this is more for experimental purposes..
