I was thinking of building a long top bar hive with straight sides to Lanstroth dimensions. I'd like to go about 20 frames long so I could but two medium supers on top for honey. Also 20 frames is about wha Id want to leave them for winter. Will the comb hold up on a bar that long and deep? I thought probably have to use frames but no foundations in the supers to keep them from connecting the comb to to the top bars in the bottom box? I already have a lot of medium supers.
I got my first two hives going this spring, medium ten frames. I discovered that I like making equipment.
