+1.Just want to say you don't have to run the Langstroth hive with frames - you could also run it 100% Top-Bar. (Personally I wouldn't - but you could). You'd need to make Top Bars with similar widths to frames and with lugs the same thickness of course - as with a Warre hive.
Re: the Top Bar length - if they are too long, cut a bit off. If they are too short, they can always be cable-tied underneath bars of the right length for now. Yes - you may need to trim combs to fit - but which shouldn't be an issue ...
Hi Jeff - adhesions to the side-walls, most likely - but as a Top Bar beekeeper I guess you're used to that sort of thing happening.Not sure what the drawback will be if I let them do their thing without a frame (other than extracting) but I extract frameless as it is now anyway.
