Basket got a lot done off camera since last time. The storage on Iron Island is now a ring of chests, four high, that runs "all the way around in a circle." And most of it sits under the ocean. Today's job is to make the ring sort items by itself.
A ring under the water
Basket plans to leave the chests under the water. The redstone has to stay dry, but the walkway in front of the chests could stay flooded. You'd swim up with "your depth strider and your diving helmet," open a chest and grab some iron. Paths will lead down onto the ring from all four sides.
There is a slime farm idea too, since Basket thinks the slime chunk sits right on top of this. Slimes would spawn up top, drop over the edge into water and get collected.
Basket also says another player came by while Basket was busy, went exploring, and "fell right through" a hole in the base. "It was the first death on the server."
Hoppers, and no air
Next come the hoppers that feed each chest. Breathing is the hard part. Basket has no water breathing potions, and torches won't go down under water, so every few hoppers it's a swim up for air or a quick pillar to stand on. "Water breathing potions, note to self."
The sorter uses the same design as before: a comparator reads each filter hopper, then a torch, repeaters and dust under it. A redstone torch won't stay next to water, so Basket brings slime blocks to push the water out of that layer.
Glass and furnaces on top
The redstone gets an arched roof of white glass so it won't break. Furnaces sit on top of the hoppers. Basket checks whether a hopper on the side of a furnace will feed coal into it, and on this test the answer is no. One of the newer ocean blocks might go on top of the lights later. Basket is "not too worried about covering up the redstone."
The redstone leaks
With three sections wired up, Basket spots a problem. The ring has no gaps between its sorters, and at the curves the chests are staggered. A filter that fills up sends out a signal strength of three, and that signal also reaches the sorter next door. That makes the neighbor think it should release its items too, and "then it'll break the whole system."
"I did not really consider this issue when I was planning to make a big ring of chests with no space in between."
Testing on dry land
Basket loads a creative test world and builds a copy of the sorter on the sand, using stone as the non-stacking filler and dirt and gold ore as test items. Powering one hopper does stop items dropping into the chest below, but the line keeps passing items along when it shouldn't. "Nope, bad design."
A viewer suggests making the ring square instead. Basket wants to keep the ring. The best idea so far is to give up one chest before each curve. Without redstone behind it, that chest becomes a dud, and the items spill over into the next column. In the test world, gold fills the first column and then moves on, so it works.
Back on the server, Basket counts how many chests that would waste. Some curves are staggered so that skipping one chest still lets the signal leak. "So that's a bad solution." Basket might "see if John has any ideas." The episode ends with the problem still open: "I need to brainstorm some more." The video ends on the credits, with no gameplay after them.
