Welcome to a new video. First of all: thanks for 100 subscribers.
In this video, I'll showcase a new tunnel bore design. Lately, I've worked a lot on tunnel bores and especially, the expandable ones. This is a prototype though and this video is mainly to show what you can expect in future video's. There are a few things going to change about the design I showed in the video. First of all, I accidentally filmed on the wrong backup. This means that in the final version, the bores will be one block higher. This is to deal with gravel. Also, I want to redesign the TNT chamber completely. The TNT chamber in this video was build very hasty so I could show the more important stuff. This however means that the TNT chamber is not a hundred percent reliable. This is because the TNT was spaced out to far, but I was to lazy to change it :D.
Over the next couple weeks, I'll make some videos showcasing the design process as well as all the parts. In this small series, other designs will be showed as well. I for example have designs where the unloading time does not depend on the with and some other interesting things as well.

![Concentric Double Stacking 348 Village Iron Farm [1.12.x/1.13.x]
Hey guys, today is a very exciting day, because I can finally show my concentric double stacking iron farm. Concentric double stacking is one of the hardest types of iron farms as has been proven by the many attempts that people have given this type of farm. Also for me, this for sure has been the most difficult farm that Ive designed so far.
Double stacking means that this farm will stack 2 villages in 1 cycle (basically exceeding the 66sec/village maximum speed). Concentric means that all the villages are stacked in 1 spot. This makes the farm a lot harder, because you do not need to cross the villages paths if you do not make the farm concentric. This is for example what I did with my previous double stacking farm which therefor is not really a double stacking farm in my opinion. That one also was about 10x easier to design.
I did make this video kinda in a rush and therefor forgot some important information that wasnt really told separately in the video/I didnt stress enough.
First of all: The stacking algorithm in this farm is totally new and very effective and can also be applied to bigger iron farms, so iron farmers: take your chance and design farms with it if you havent been thrown off by the 1.14 changes yet.
Second: the stacking happens in 39 seconds/Village, or 78 per cycle of 2 villages. This is still 12 seconds above the max double stacking speed of 66 sec/33 sec per village, but faster is not obtainable with this method. 39sec/Village is also pretty much faster than any concentric double stacking farm that is released as of May 2019.
Third: the farm actually works in all quadrants. Im really proud of this since it wasnt easy at all to make it work in all quadrants. Normally the challenge in iron farms isnt as much getting it to work, but mainly getting it to work in all quadrants. For this farm, it was already a challenge to get it to work. Just imagine how difficult it would be to get 1 version of this farm working in all quadrants without any double door registration issues...
fourth: I tried to make the farm as survival friendly as possible: the farm does use 2 sticky pistons in a hopperclock (clock can be replaced by other clocks as long as it is exactly 1560gt), but apart from those sticky pistons, the farm does not use any slime. Also, in 1.13.X you can replace the pistons on the doorwing with waterlogged trapdoors (same way as shown in my 30V iron farm). This means that the raw (uncrafted) materials for this farm pretty much consist out of some wood, blocks and redstone but almost no iron to craft pistons.
Finally: this farm will obviously break in 1.14, like all other traditional iron farms. I do acknowledge the opinion that it might be wasted time to still design iron farms, but I really enjoy designing them, and I will probably continue doing so. I dont think we as iron farm designers should care too much about how often our builds are being built up in survival, and mainly care about the fun that we have while designing the farms. And after all: by the looks of things, the big technical servers definitely stay in 1.12/1.13 so they are still in need of new iron farms :). Therefor I will definitely produce some more iron farms. Also, let us be thankful that we are not forced to update and keep in mind that we can always use that in our advantage if we benefit from it.
Anyway, thank you for watching and reading this story: ~Comet
