- Change of plan, this was meant to be the air pump episode, but that much happened I postponed the air pump for 2 more weeks to get it built.
In this video I get the boring machine stuck and struggle with floods as well as some tunnel strength testing.

why do people love videos of people digging tunnels so much. Me included lol
People dig videos of tunnel digging 😂
We used to dig tunnels when we were kids
I’m 64, as a kid my parents to shut me up gave me a spade at the beach, I love digging and still do know…. it’s a man thing!😂
Armagedon ?
So true😂
Dave you're gloriously bonkers and I love it.
I knew the gaps between the side/floor panels not being watertight would be a problem, but I'm not surprised you have a clever solution. Nice one.
Keep it up mate you're doing brilliant.
Thank you , I know I’m insane but it’s great to get positive feedback 😀
It’s great seeing the different approaches to tunnelling. Due to the sides being fully supported and resisting the outward motion, I imagine they are stronger in the ground than in your test.
Yes and I am putting all the force in the middle and in real life it’s spread across the full panel 😀
Another awesome tunnel video, I like the sump idea and sending the pipe down the rail, you could do with a clip on buffer to stop the tunnel bore from running off the end of the rail maybe something that catches on the rear of the tunnel bore that allows easy adjustment
I’ve got the pipe in the rail now and it looks so neat in the tunnel, shame I ran out of time in this video. 13ft in now 😀
Part of the "fun" is the water though. The idea of building a 2nd floor deep near/under the water level makes it that much more "secret" and "daring" !... Hope the pump doesn't stop.
Excellent, good to see the miniature Land Rover in winch action again!
Yes I always like bringing it into the video somewhere 😀
grateful the weight test haha, had my doubts for sure
Good morning, I have been loosely following your escapades, and not leaving comment, Oops Sorry. Now that you are up to number 5. I have gone and binged the ones I missed. I give you credit for working hard. I am claustrophobic so I have had a few issues watching you, But I am just fascinated with your progress. Keep going and I will catch up in number 6. Cheers
Thanks for the comment, things have got a lot more claustrophobic in part 6 😂
That victory moment.... Funny how a metal bender solves all their problems by bending metal.... ha ha. great project!
I love using cad, the plasma and the press brake on the videos, plenty more to come 😀
Great episode! I'm so jealous of your metal working skills - looks awesome and is so strong. On another subject I swear tunneling is a form of rain dance 😂
Yes i agree me and colin have been battling against the weather lately, nice and dry now I have fitted the pump., 13ft in now, I’ve got it plans when at 16 ft 😀
Liked and subscribed. Really interesting project, great skills with the metal fab, and the vids are very entertaining. Good luck with the tunnel, I can't wait until the next video 🍿
Thankyou for the nice comment, loads more to come here 😀
Finally No.4. I think you should test 2 containers on the sections, just to be double sure. Also the wet gravel looked like you had a bad curry and used the bucket as your toilet. I would love to come visit when im next in the UK. Love you videos. Cant wait for No.5 ❤
I have thought of a way of testing the tunnel strength, I will try and get it done for the next video 😂
Musta been real hard for the prisoners who escaped via tunnel. You know having to find their own plasma cutting cnc and water pumps and whatnot..
Yes and treadmills 😂
Add water weight and possible additional kinetic energy from a void collapse
to simulate a void collapse, set it back up under the container but this time drop it from a foot high or more onto it
to simulate a void collapse, set it back up under the container but this time drop it from a foot high or more onto it
You need something to hold that container together, it’s too much weights for it. Maybe some concrete or Beams of steel. Love your videos btw!
Do you mean the buried shipping container?
@@Tornado_Dave yeah, I was a bit drunk when I commented, I might be wrong 😅
Got me tuned in!
Glad your on board 😀
bril chanel and good series
You’ve certainly got some patience Dave 👍
Just got to keep your head down and think 1 foot at a time 😀
@@Tornado_Dave beats building comp motors then 👍
I hope you get up to 1M subscribers by the end of the tunnel. I need more RUclipsrs digging tunnels!
I would love to get up to that level 😀I will link up to my workshop if I get that many 😂
Brilliant bit of calculation and testing not to mention all the very clever engineering. I'm still confused why it's Tunnel "Dave" and not "Tunnel" Dave but at this point I'm too scared to ask. Carry on to the next.
It’s more the reference of the tunnels from the great escape being called tom dick and harry so I thought it was funny to call mine Dave after me
I feel like your system needs a redesign for a safety disconnect so you can quickly pull it all apart.
Colin furz makes it look so much more graceful lol
I’m an amateur compared I know 😂
Great stuff Dave. 👍
Thanks 👍
Absolutely fantastic!
True British grit !!
Never give up !
Where there’s a will there’s a way !
Yes just got to put the commitment into these projects, to be honest compared to building race cars from scratch this project is a walk in the park 😀
Wow that’s a tight space
It will be when it’s lined with wood 😂
While youre homemade TBM might not be quite ready for mass production yet, I find it incredibly ingenious and enjoy watching your progress! Stay safe.
Yes it’s not the best machine around but starting with a treadmill I think was a funny idea 😂
@@Tornado_Dave Absolutely! But that's where the engineer shines through: combining absolutely unrelated items into a workable machine that actually makes your life easier (at least when it doesn't break down and a series of bad decisions gets it wedged in a flooded tunnel, haha)
nice work ... Dave 🙂
Thank you! Cheers!
Been waiting for this video so bad, thanks m8.
I will do my best to do 2 weekly updates from now if I can 😀
Very entertaining to watch your problem solving methods...a wet /dry vacuum to clean grit & gravel debris out of the nooks would be a definite asset ! Almost like hydro-vacuum operation. Tunnel on!
Thanks, glad you like it and I think I need to try the vacuum 😀
EPIC !! As always! Thanks for sharing as always 👍
Thanks again for watching and nice comment 😀
from another Dave, hello, I am curious why you are not going full height? Love your digging machine!
Good question! Because the theme is the Great escape and I have big plans for what’s going at the end of the tunnel. Tunnel size is fine on the electric cart and is more fun than walking 😂
Brilliant episode. I had all the confidence in bent sheet metal supporting the weight. Seeing you test it was a good idea.
Thank you, yes it gives me confidence when I’m in the tunnel as well 😀
The subscribers is a nice added touch 🏆
The subscribes wall of fame 😀
Very impressive mate.
I am setting up to go horizontal from a ten foot deep, three sided hole. I am thinking using the sawsall with nine-inch brick/concrete blade from Temu. If it cuts a block form, it ought to snap out.
Maybe a hole for the water, with a hose, the water could be pumped out.
You are definitely knee-deep.
Sounds like you have harder ground than me! Are you filming it?
@@Tornado_Dave It is decomposed granite. It seems the deeper it goes the more dense it becomes. So, I am at a transition zone. It still crumbles into a sand structure, easily pulverized, yet pretty firm. SW Desert Rainforest in NW Arizona. I thought you were in Aus., but you are in Britain?
P.S., I am thinking chamber, rather than tunnel, unless Gold shows up.
Looks good Dave definitely feels safer after your good test. Amazing channel growth.👍
Yes it’s given me piece of mind 😀 yes the channel has been growing well, I hope it continues like this 😀
Never a dull moment with you is there? lol
It’s how I enjoy life 😀
Your weight testing is so hilarious 😂 Such good work mate!
I thought it would be a different approach to weight testing 😂
good job
congrat's
Thank you 😀
Not sure about your weight calculations Dave. I'm not being critical to be unkind, just because I'm concerned for you.
You need to factor in the weight of the volume of soil above you and then factor in additional weight for water.
Furthermore, you should have a bigger safety margin. If you expect a tunnel section to need to support a maximum load of say 1 tonne, you should test a section supporting a load of several times that weight. If it were my life at stake, I'd want a factor of at least 3 or 4 times the weight.
Then you need to consider that although your sections are galvanised, the edges are plasma cut and no longer galvanised. Likewise, any holes drilled are going to break the galvanising. Those are going to rust over time, so they will gradually get weaker over time.
Don't mean to be a killjoy, but I really don't want to read about a horrible accident in the future.
Look after yourself!
Thanks for the comment, The weight calculation was probably 4 times over the actual amount as I put all the load in the middle of the section and in real life that is spread across the full width.
I cut a lot of galvanised steel on my cnc plasma rather than get it laser cut as the cut edge re seals and doesn’t rust, I don’t know how it does it but I have never had any corrosion after cutting on any galvanised unless I have to sand the cut edge! It’s pretty handy that it does this 😀
Wow is that right? Never knew that. I suppose the plasma cut is a form of accelerated oxidisation, so perhaps it leaves a layer of magnetite or something?
Now I'm going to have to read up on this!
Keep going with your vids. Love them!
Been waiting for this 😁
So close to 20k!!!
Horse, you could do with sumps every 4 / 5 meters as you go and stick a sock round the base of the pump or it will silt up . Great effort , you never been a quiter for sure and looking forward to see day light at the end and lad needs a tipping trailer hope your not making him shovel all that lol . R2
Yes tipper trailer needed, it’s on the list 😂
Nice work. I wish I had round river pebbles to dig up at my place, like you have.
They are really expensive to buy too.
I probably need to separate them and bag them up 😀
Bonkers as a brush. 🤪
Dave for a start Colin Furse hasn't had Guy Martin in his tunnel 😅😅, so you get brownie points for that ... loving what you do but I think you need to make it bigger so you can stand In it ... 😅😅 great work tho dude 👏 👌 😊
That’s true! My theme is the great escape so want to keep the tunnel small, also I’m on the limit of how far down I can go due to flooding and if I made it 6ft high there wouldn’t be much soil left on top so may as well just dig it with the digger and save all this effort 😂 I think the tunnel size will make it better on the long run for what I have planned 😀
@tornadomotorsport I feel you dude you are doing a great job , fantastic content 👏 I think the bilge pump will work and summer is just around the corner ...
At this rate, you will be at 1 million stubbs before you hit the house 🎉
That would be nice but my original target for this year was 25k so if I hit that im happy 😀
caves, water, mud and stone... The earth calls...
Novel idea... love your ingenuity... the great part is that your corregated pannels, like timbers of old in mining, give strength to you horizontal "mine shaft"... being reminded of the chunnel... they dealt with the water in their tubelar shaft under their rails with a sump pump...you may need a collection tube ( like weeping tile) to collect water at a central low point for your sump...just thinking... as Im watching, i think you are almost their anyways...
The water seems to flow to the low point where the pump is no problem, I’m having no problems digging at the moment even with the rain, just starting the 15ft now 😀
I would add a drain of some kind along the bottom (under the metal) that slopes back to the well for water to drain out
The tunnel slopes away from the bunker slightly so the sump pump does the same job as this 😀
I wonder if my neighbours would notice if i tunneled from my shed to the village pub...
The pubs a mile from here so don’t think I will manage it 😂
As nice as all that math was, and trust me you do a sight better than most tunnelers. It doesn't take into account the lost of pressure due to frictional loss side to side and between aggregate pieces. So the reality is you are much much safer than you need to be.
Yes I realise about the friction and the weight will be much less but thought it would be nice to demonstrate this just to prove they can handle the weight no matter what. Got to drive the digger over the top next 😂
So hard to work in a small space. Wonder if it would have been just as easy to make it bigger
My idea was to make it hard to know what it was like for the boys on the great escape 😀
Should make a mini crane that pivots and make a whole new bucket for it
Did I miss something? How do you plan on running lights and pump air into the tunnel? You would have to have multiple air pipes to circulate air.
The tunnel is getting lined with wood when it is finished. Lights and air ducts will be on show as per the original 😀
11:30 I'm not sure that's correct, in that the load of the dirt above is carried at 45 degs, not all the dirt straight up&down. i.e. if part of the tunnel collapsed it would be a triangle section that would come out (like when you knock out a lintel above a window). Therefore 750kgs is probably way over estimated imo. But better safe than sorry I suppose! Good work.
Yes this was worst case scenario, it will never see loads like this but it was a good demonstration I thought 😂
why so small tho .. what use is the tunnel going too be bud ... its interesting too watch and is radically different from what FURZE is doing ..
Mine is based on the great escape and you will travel the tunnel on electric carts, I think it will be cool when it’s finished and I have bigger plans in the pipeline yet 😀
Where are you off too. Haha
Gradually getting towards my house 😂
When can we come and have a look
Tell colin to give me a bell, Guy has passed my number on, the kettles always on 😀
I hope I'm invited to this little meet up 😊 You know what I drink Dave 😂
Couldn't you cover the ground area above to lessen the rain seepage? Mind you I have zero knowledge here I'm just curious though.
I was thinking that myself 😀
I would have given up before starting to dig.
It does take some commitment to keep spending my evenings digging 😂
did you add to the weight of the soil if its soaked with water ?
Even if you go on the wet weight it still isn’t more than the container, and the container was putting all the weight in the middle 😀
Hi, I reckon a RH14 would be a good investment for you.?
Hi Dave, regarding your test for weight. I maybe wrong but as the container was only supported at one end by two of your tunnel section does this not mean that only quarter of the weight of the container was be held up by each tunnel section. Also do you need to consider the weight of all the water above your tunnel as well as the gravel? 🤔 whether I am right or wrong stay safe my friend.
Yes the weight was divided by 4 and also the door end is heavier on containers so about 1 tonne on each section. Also I put all the weight in the middle, in real life that weight would be spread all the way along the section. So I was 250kg over the weight and concentrated with no flex at all. Maybe I need to do a bigger test next time 😀
How deep is the well & how much of the stairwell is below the water line
The well was originally 33ft deep but was in bad shape at the bottom with the ground moving sideways along way, so I decided to fill it in to the good part so is now 25ft deep with 15ft below the bunker. In summer you can go all the way to the bottom as it becomes dry
Good evening Dave.
You might consider changing the text color of the chapter title from white so it stands out.
Ok thanks for the comment I will do something about that 😀
Does the well go down any deeper?
Yes 15ft further, I showed a bit more on part 3 😀
@@Tornado_Dave Was it originally dug to be a well or as a bunker? Thanks for the reply.
@@jasonh8470 it’s an old WW2 site and the well was dug as a water supply, the buildings also had water towers next to them. I put the doorway through it.
@@Tornado_Dave Thank you again for replying. I appreciate knowing more of the history.
Will it not get all rusty?
It is all galvanised steel so should be ok for quite a few years
Why use air conditioning duct as bracing 😂
😂I suppose it does look a bit like that!
Fuck, having trouble seeing the joy in this.
50% of my mates think I’ve finally lost my mind, the other 50% think it’s brilliant 😂 so your not on your own
Look I’m really enjoying this, I think 10k subscribers deserves more content 🤣
shorts ⬆️ Community pictures ⬆️
You need to increase it 🏆
Yes I will post a bit more, always seems a bit quiet on the community so not sure if anyone sees it 😂
❤❤❤👍👍👍
When's the next video coming?
Friday 5pm this week if I get it finished ok time 😀
Make sure you're not in a radon area 😊
I’ve just checked, very low here 😀
You must be spending a lot on sheet metal
About the same as I’m paid off RUclips if I’m honest 😀
Tree fidy ?
The metal will rust and corrode and cave in with all that water and soil pressure on top.
The entire top above the tunnel needs to be isolated and protected from the soil and water, and there needs to be a drain to drain out all the water that comes from the top soil above the tunnel and sides and bottom and drained away, but for that the entire tunnel will need dismantling and re doing.
Then you need something else like cathodes etc, to prrotect the metal from rusting in the moist of the soil.
The entire project is a disaster and a disaster waiting to happen.
Problems.
1) water draining from above to the tunnel below.
2) pressure from the soil above.
All I can see is a future cave in and tunnel collapse.
I was hoping being galvanised it might protect the steel a bit
@@Tornado_Dave but there is nothing supporting it from collapsing from the top and sides, nothing giving the strength to hold the thin metal sides and top in place, the thin metal where they inter lock on the sides is not strong at all, infact very weak load bearing, and when the sides of the metal rust and corrode they will weaken even more ( if they have not buckle and collapse before ), once where the water corrodes the unprotected metal area and the rust eats away further along the metal, as the metal is very thin, the structural integrity will be seriously compromised. Especially with all the weight that is above it which is not being supported by any structural strength.
Likewise with the sides and how it connects to the bottom, there is nothing supporting the sides and bottom, same thing as above, the sides are not locked in or supported to the bottom, there is nothing supporting them from either collapsing in or sinking further down because all the water pooling will rust the entire thing underneath, especially how the metal is so thin and unprotected from water and soil.
Why you think so many mining tunnels collapse, not enough structural support, like with any building, they need a firm foundation which the sides can be fully supported on without collapsing in any direction such as left - right - front - back, and enough foundation support it can withhold vertical pressures.
Then when the roof is put on, the sides needs to be strong enough to support the weight of the roof and everything that is put on the roof, which also the foundation needs to be able to withstand also. In addition to that, the roof needs to be so strong interlocked with the sides so that it does not collapse and break away from the sides, the roof needs to be strongly secured and fused into the sides so they do not collapse and break away and then have a roof cave in.
With your one, I watch video after video, and never see anything protect from water and moist build up and rust and pressure from cave in, and nothing really locking the the 4 sides or any secure foundation.
I keep seeing and thinking, where and when is the cave in collapse, its just a matter of time.
В России тебя тоже смотрят 🤝
I can't help but feel like you've made the tunnel too small and you'll want to make it bigger in the future, so you can walk through it rather than crawl.
I’m not going to be crawling,I am using electric carts 😀
Get a wet vac
This is not only claustrophobic, its stupid af. If you made the tunnel 2x bigger, it would take 2 times longer to dig but it would be 10x easier to do. Plus, you could ride a card in a seated position.
Allot of skill and ingenuity, but man the tunnel is just too small to be any useful and enjoyable to use.
It’s more for the effect of what it represents, it’s a recreation of the Great escape tunnel, once finished and fully operational you might see it in a different way 😀
Please don't ask to like and subscribe.... If your content is good. It will grow naturally... Will be a better channel in the long run. 👍
I know what you mean, I hate it when I see it on videos but when I do ask it does seem to help the video. Next video I promise it to mention it 😂
Take it easy guy. He's tunneling for our entertainment.
