I could do other tunneling methods, but I really want to make a TBM specifically

I want to make a tunnel boring machine for digging ~2 meter tall tunnels in sandstone. Sadly I live in a place with only sand in the underground and that’s not suitable for digging tunnels DIY style
That sounds like a harsh thing to say, even if it’s their last day

The Danish Air raid sirenes allways gives me the creeps, I think it’s the clear sound that gets me. Unlike other sirenes that has a harsha tone, the Danish ones have a almost sterile tone, convaying the feeling of “this sound is vary important, stop now and go Inside. Like a scary Teacher”
Starts at 0:15 and later has a “all clear” tone later on on youtubes
Then again it might just be because I had to listen to it as a kid, and I was a weird ass kid

I can suggest simply looking around YouTube. That way you can get a sense of how they work and what kind you’d like to know more about. I happen to have practical experience with the, because I used to work on trains that had some giant versions
I have a fascination with VFDs/VVVFs/frequency inverters. They are the controllers that gives of a specific hum/whine from electric trains/cars and from other 3 phase electric motors.
I’m making my own sudo-vvvf at home. I just think they sound awesome and are Hella cool

Whenever i have a knife and see a thick electrical wire i have to stop myself from “just testing” what would happen if I cut into it. I work with 400v ac on a construction site a lot and I know what would happen lol.
