Build This No Ancient Debris Tunnel Bore in Java 1.21 [1.16+]

This is the full block by block build tutorial of Underlein's Trident Tunnel Bore, one of Minecraft's cheapest and most efficient tunnel bores. A tunnel bore is a mining machine that uses TNT duping to throw TNT forward then move the machine forward to repeat the process again.

Unlike Borkon's tunnel bore (fantastic btw and used by Mumbo Jumbo previously), this bore requires no ancient debris and blasts a larger hole so more ores are exposed.

Underlein has allowed me to build this tutorial and as far as I know, it's the only one for this tunnel bore. His one request was that I credit the original machine designers that he combined: Yisibite and Reschenmachine.

As far as I know, this is the ONLY full block by block tutorial for a tunnel bore without ancient debris on Youtube currently.

NOTES, CHANGES & UPDATES

The "temporary blocks" under your platform should be dirt, not stone, logs, moss or anything else that may change the pitch of the noteblock and trigger it. I didn't notice because I used dirt which is safe. If you are using a temporary block other than dirt, place the noteblock on the dirt then remove the dirt under the noteblock before adding the observers.

This does NOT work on Bedrock, TNT duping MUST be enabled on your server and the answer to EVERY question of "how do I fix" is "rebuild it how it looks in my video."

You need to clear gravel, water and lava from in front of and on top of the machine or it will break.

Light up WELL around the bore so no mobs spawn on top of it and no bats knock the minecart around.
