I make mine with dowels for side bars. Bees space isn't a problem because:
1. the bees usually do leave some gaps in the bottom corners of the frames. They always leave room to go where they want to go.
2. The dowels are not as far apart as the top bar, so bees can move between them.
3. Bees crawl under the frames.
4. I put the dowels where they are a bee-space or so away from the sides of the hive, although I don't worry too much about getting it exactly right. When I string wire on them (which is a minority of the time - only when I'm doing cut-outs) the repeated wire tension bends the dowels even further away from the walls of the hive.
In my case, I have a double layer of 1/4" hardware cloth for the bottom. The bees go through it at will, wherever they feel happy, but they don't attach comb to it - at least not yet.
