The author appears to have forgotten his lessons on what a 'beespace' is. I predict the bars will be locked together with propolis by the end of the season. The 'beespace' is the key to a movable frame hive. No 'beespace' the frames won't move.

You will need to lift the bars and comb straight up for inspection, this will be difficult with the hinged lid, much easier if it came right off.

Bees hate movement and vibration, I would lose the chains and set it up solidly on the ground if you don't want angry bees to cope with.

Be careful if you are going to stock it from a swarm, they are often diseased. Have them checked by someone who knows what's what.

Have fun, a hobby that pays as you enjoy it.
