We aren't as good at engineering as Furze, we just duct tape stuff together!

he reminds me of cody's lab

And none of Colin Furzes' horrible music

I hum that sound effect every time I go down there 😅

This has been unlisted for the last 4 days.

Let me know if Jim needs a green card husband for some Canuck health care. I jest but damn...

Never mind I just saw your message about stability. Perhaps just in areas that are stabilized, or maybe as a way to loosen material before tunneling further

No crime in Europe 🤔... 😂.

Why do you feel happy in Europe? We will become a battlefield soon 😢

​@@John-wd5cbunless your in a neutral country

​​​@@hughjanes4883no neutral here, already sent weapons 😢

I'd like to visit there sometime! We need a big vacuum truck like that for Sandland.

Howdy! I think we may have actually met briefly, I've been to Underground a few times and Jim talked about Sandland the last time he was there. KZfaq is terrible at losing comments and replies, but you can shoot me a message at gabe@saveitforparts.com or maybe I'll try to email you.

@@saveitforparts We probably did meet! Funny what a small world it is. Still not sure if I can make the next Underground. Unfortunately it usually lands on dates when I already have plans. 😞

Ha, sometimes I wonder if I'm just spamming KZfaq. I actually have a backlog of 5 or 6 videos right now, I have too many hobbies 😅

@@saveitforparts it's fantastic and refreshing. Loving the reviews, take all the free stuff you can!

Thanks! Jim is feeling pretty positive under the circumstances!

@@saveitforparts that’s great to hear Gabe. Hopefully he’ll be back up and running again soon. All the best

I've been out there off and on this summer, not sure if I'll get around to digging on the next few trips though! I've been neglecting the monorail and it's full of racoons again 🙁

I grew up on an island in Alaska, so I pretty much grew up wearing those :-)

@@saveitforparts I still don't own a pair of shoes, SE

The humidity is something of a feature and actually helps stabilize the sandstone. If it dries out it gets crumbly, but if you leave it alone it stays stable pretty much forever.

We've dabbled in pneumatic sand moving with just a shopvac, it wasn't strong enough. We don't have city power, so any vacuum or conveyor system has to run on a gas engine or small generator.

You're more astronomers than I am! I'm just a guy with some stuff I found in the trash, wondering what I can do with it :-)

The Soudan mine experiments were primarily about filtering out comic ray radiation. So extremely low background radiation was needed. This they're trying to do something with RF, so low EM transmissions. Similar in that both environments are looking for low noise, but entirely different kinds of noise. I'd be really curious what they're trying to do, and why this is a good environment. I'd expect an radio signals from 327 mhz wouldn't penetrate earth well.

Glad you like it! I also duct tape boats together and annoy railfans, I have a wide range of silly hobbies!

Mmm sand salad 😋

Is that a Minecraft reference? Last time I played, the main danger was random lava :-)

We've tried that and it broke pretty fast.

Looking at the condensation on that cell signal booster, I don't think they manage to keep the air dry at all.

@@Hexen_Wulf I wonder, is that the normal amount of condensation or what remains after drying in the air. If the humidity is too high, it is advisable not to work with electrical appliances powered by mains voltage.

It stays pretty humid in there. Our AC power is in sealed conduits with outdoor type outlets. We don't have power in there all the time, just when we're working.

@@saveitforparts Thank you very much for the quick response, then that clears things up. It's a good thing to have all electrical components designed for outdoor use. An electric dehumidifier requires continuous power, which wouldn't make sense in the cave if you don't have a permanent power supply from the grid.

@@saveitforparts You know, I bet you could rig up a land line system in the cave, just for talking to people in other areas (Not outside calls). I'd be shocked if you didn't have an old army phone, you know the type you have to crank up for power?

Depends on what kind of sandstone. There are whole cities in Turkey carved out of sandstone, and parts of of Italy are on volcanic sandstone-like material and full of tunnels. Lots of old mines and quarries and tunnels in various formations all over the world :-)

@@saveitforparts your probably right but I personally would not trust it. Its also a forested looking area so would be worried about what forces tree roots are exerting during storms etc

X-Files music starts playing in the background

I've played around with some radio stuff down there, but unless we bring it down, or it's strong enough to get through the bedrock, you can't hear much!

;)

I think it's just something about the sandstone that makes it hold onto water, I'm not really sure! I know some of the deeper sandstones (below the water table) make good well sources.

This is Jordan Sandstone. We have a few supports in areas that had cracks, and in some other spots we have drop ceiling for aesthetic reasons.

@@saveitforparts awesome 👍 thanks for answering

It's very narrow gauge! All homemade with wooden rails and little carts.

@@saveitforparts What gauge? Also I don't understand why you used narrow gauge as a adjective.

We're in Jordan Sandstone, it's technically a bedrock made of compressed / fossilized ancient beach. The digging is pretty fast, it's the hauling sand out that's the slow part and takes a lot of volunteers!

Something with nazis maybe. Oh wait! They shoot that in Ukraine already.

That was filmed earlier, I had this video almost done when he had the car accident.

This one is a Marauder Mini. It's been pretty bulletproof so far, although I have run the batteries out in a tunnel when I wasn't paying attention to the charge level!

@@saveitforparts thanks! 🤗 I will have a look into the specs myself! 🙏

That would be fun, I bet we'd need more water or something!

No prob, someone always asks! The sandstone remains stable as long as the ceiling is arched. There are a bunch of local caves / mines / tunnels in this geology and the similar St. Peter sandstone that we can use for reference, some are 150+ years old and some natural sandstone caves are even older!

Thanks for sharing! Wow it must be a treat getting to explore so many cave systems nearby. I live in Kentucky near Mammoth Caves and Cartee caves. Always loved exploring them! This is such a cool project. Looking forward to your next update, and I hope Jim feels better!

He's digging in softer topsoil so he needs to overengineer the cement shell, we can just do raw bedrock if we arch the ceiling. I think it takes him a lot longer and costs a lot more!

Spoopy!

@@saveitforparts Don’t blink.

🤣

Welcome to America! Where you never know how much the hospital will cost, if it will be covered, or how you'll pay for it!

@@saveitforparts I mean I know the memes, but after doing some 2 minute research insurance prices and services seem to be pretty similiar to EU standards, just that they're optional things to get. does slim jim have insurance at all? xd

Insurance in the US for auto and medical expenses are designed with difficult to comprehend language, coverage blindspots all over the place, and many times even when you're "covered" for part of something happening a random specialist or treatment or medicine or location you got treated at is not and there's no way to request to only have things done by things covered under your insurance. Neither doctors, patients, or anyone invlolved in care have a surefire way of knowing what will or won't be paid for by insurance before something is done, only after. It's essentially financial Russian Roulette. It's possible for doctors to work in the same hospital and have some but not others be paid by your insurance, and you don't find out until months later because you were never personally billed, your insurer just refused payment, then you discover you've been sent to collections for a bill you've never seen. It's fucking awful and there's no solution, by design. Health Insurance companies in the US are leeches bleeding us to death in our most vulnerable moments and pay handsomely to keep things that way.

@@carpespasm I see.. so while healthcare exists and is affordable, it's spotty in its coverage. Interesting. Was this obama care thing any different?

Yeah, we have all the wrong tools for the right jobs 😂
