I’m from Yorkshire in England and we have over 5000 miles of dry stone walling in Yorkshire, what you’ve made looks beautiful and is a real piece of old style engineering. We’ll done pal.
Nice job guys! I like to use a little stone dust to help w some of the teetering between the stones. Is that enough mass on top to maintain the compression on the arch stones!
It takes time for the stones to set. You must poor grit all over it and get a rock and tap to make vibration run through the brigde so the grit falls inbetween the crevices.
That's a pretty cool bridge. Probably a good idea to let it settle for a bit before walking across it. I think we would all love to have one of these in our back yards.
That and a swing bench ❤ I got a wood swing bench but the previous owners didn't oil it... Does anyone know if I can hold it together with epoxy. To one day have a dream backyard
In Rome, when a bridge was opened, the engineers and their families stood beneath as the first carts passed above. And that is why some Roman stone bridges stand to this day.
@@aarontoothgo do what? ... stand under bridges after they're built, or build bridges that are still strong after two thousand years? And, still in regular use where they stand. No modern replacements are built next to them, because they're fine! I just don't understand your comment here
Guy #1: "Go STAND on it." Guy #2: "No. You go stand on it " Guy #1: "I am NOT going to stand on it. YOU stand on it." Please show the follow-up video of you two standing on top of your handiwork.
Who would’ve thought of that? Hands down you’re smarter than the man who built it! I know it’s not an engineered bridge but if one is going to build such a bridge(walk way) then one must be able to QC their work. Like you suggested, leave the loose form setting underneath then go walk across it and jump up and down on it. As he said, it’s gotta set there for a while,………what difference does that make? Either it’s stable or it isn’t. Time will not make this friction interlocking design anymore secure even if you left it to stand for decades. Great point you suggested!
With the form removed the stones will settle under gravity a little more. I dont see a key stone though which worries me. Also they baisicly used shale. You can have a dry stone arch bridge with much larger pieces of stone
@@seventeen912 could be a case of if it was unstable and fell, at least they could enjoy how nice it looks until they test it to find out it will collapse. I know if I had just built something like that and you are really tired it would feel more crushing emotionally knowing all that work you just did was for nothing and had to be done again, in this case sounded like it already was the second time. give yourself a fresh day to test in case it falls then you'll be in a better position to fix it then and there
Yes and normally a round arch needs a greater degree of completion. Normally to atleast 180 degrees as the pressure on this bridge is transfering sideways not mostly down. Thats why most bridges like this were called hump back bridges. To get the angles right
Beautiful! Not bridges, but hand cut stone tunnels under the 1850's railway tracks in Niagara, the largest 160 feet x 20 feet x 20 feet still standing. And fun to paddle through! Everyone forgets the form work the carpenters had to do first to make them a reality. Thanks for posting!
There's ones near me in Australia, handcut in the 1800s to allow a water pipeline thru a few hills, 2 or 3. They're properly caged in now but 10 years ago, I went up inside one on a hot day, about 25 meters. Cool inside and it was just solid stone in there.
Beautifully done but I’m certain that the original dry stone bridge makers would have happily incorporated cement if they had access to any. And if you would have used some in the sub layers there wouldn’t be any arguing about who is going to be first to walk over it.
We never found out what happened to ol' Daniel Renwald after that fateful day. Hopefully, Daniel finally crossed that bridge and walked into the light. However, some still say that on lonely fall nights just after the sun sets, if you sit quietly and listen to the wind, you can still hear him shouting in the distance "No! It's gotta stand there for a while!"

TBH it doesn't look very strong at all. 1) It would be better if the stones that actually make the arch were more of a wedge shape so when there is a downward load on the bridge they are compressed together, making the arch stronger. 2) There is no cement to hold the stones together and stop them sliding against each other. Nice folly though!
I'd jump up and down on that bridge if I built it. He's not going to chance it because "it would fall and you would be trapped under a thousand pounds of rock". Dude, he never asked you to stand under it.
If the bridge collapsed the first part to fall would probably be the part under load, where the person is standing. Then the rest would fall down around it, likely doing bad things to that person's feet and legs (if they manage to stay upright).
@@BobfromSydney Bob, if you can't trust something you built to be safe, you shouldn't leave it as a possible death trap for others. I guess there are two types of people in the world: those who are afraid of falling, and those who aren't afraid enough.
@@paradiselost9946 Suppose that's true - a couple stones aren't in just the right place, so it falls in a couple minutes. Do you want to be standing on it when it falls? Or standing 20 feet away?
@@senseisecurityschool9337 not just in the wrong place but the wrong shape... along with the wrong foundations for the loads and the wrong curvature for the span... its too 'splayed out". should have at least broken it into two spans. the wider it gets, the more the weight transfers sideways, and the more you rely on the stones being properly fitted... theyre generally tapered for a reason. and some of these stones are tapered the wrong way! drystone doesnt mean "zero effort in dressing stone to fit properly". arches are simple but they rely on the whole thing working together. wedge themselves in and as long as they cant bulge out sideways, or fold inwards, all is good. if they "settle"... they collapse. (welllll.... debatable?) this would have worked better as overhanging layers more like the side walls are, considering the thin bits of flagging they used. everythings acting down and its the weight of overlapping layers keeping it down. not really arch material, what they have.
It looks like the scales on the back of a little dinosaur, and it's cool🙂 There will be a noise when you hit it with a hammer,remove the formwork. That's a wild sound.
there isnt enough damage yet. it has to be a lot of damage. that said, he may take all the stones, bring them back to the quarry & glue the whole mountain back together. because THATS a LOT of damage!
what the hell am i saying, phil swifts endgame is obviously to bring the whole universe back together to its state before the big bang. because that is truly a lot of damage. its all of the damage.
Let it sit for a while. Masonry moves and shifts and copes with movement well (if properly built). It will settle, and be better and stronger for it. Congratulations to the mason and builders!
(0:50) I'm almost certain that a variation of this dialog was uttered during the construction of the Great Pyramid of Giza. Similarly, much like three of the worst words (and their various equivalents throughout the ages) that have ever been uttered: oops, uh-oh, and oh no.
