Good video! Just a tip: when you go to drill the semicircular notches with the Forstner bit, it's much easier and more accurate if you gang a pair of the 2x4s against each other, edge to edge, and drill into the valley where they meet. It makes the bit self-centering, and ensures symmetrical notches. (It's also twice as fast.) Bar clamps work fine for holding them together while drilling.
Thanks man! We've just started, so hopefully we'll get there soon. Have a couple of videos coming out over the next week, so please subscribe and share with people you think might like it!
At the next visit of my grandson or granddaughter ( eight years old ), the wood will be ready. What a wonderful project to do with children and what a surprise. Pierre Grégoire, La Malbaie, Québec, Canada
If you wanted to use this bridge design as the top of an arch garden trellis, that had 4 straight vertical legs, how do you determine the length of each bridge piece to build a specific base width of the arch trellis?
Your channel looks like those of 100k or 500k subs. Truly like the video quality. Just by the way, if you film far from where you are speaking, I think you'd like to get a mic :)
Militancia Católica Thanks! We just started, hopefully we will get there. About the audio, you can see we had lav mics on our shirts while building the bridge, but there was a corrupted audio file when we went to edit. Had to use the backup audio from the shotgun mic on one of our cameras.
suggestion for drilling? Clamp two 2x4s together and push hole saw right in the middle making two half hole slots with one push and avoiding hole saw climbing out of place ...allows the guide bit a center hole to follow ...no?
Using this to make an arch ramp for small motorcycles out of pallet wood, thus dispersing the weight over the two contact points while preventing the sharp angle at the top where machines drag the middle.
You had used an 1"1/4 round wooden bar and 2" x 4" rectangular bar. Does it work with 3cm round bar versus 5 x 5cm square bar? Do you have a document specifying the load which can withstands this bridge? I am willing to build one; however, as a mechanical engineer, I am not familiar with structural or civil design.
Would I be right in thinking that the bridge is narrower at the end you start from (left hand in the video) & wider at the end you finish with (right hand in the video)?
I wonder would bamboo work and have a bigger arch, and have maybe three joined side by side,then cover it all with netting to keep the birds off strawberries and cabbages. You could tie the canes with plastic ties. This has great potential with gardening ideas.
there is a comment in French above that says this bridge was built first by the Chinese, about a thousand years ago. I would of course guess without having researched, it was probably made with abundant resources like bamboo- probably wouldn't even have to be carried far...
Good job u and ur son did together.. Always nice doing stuff like that together. Longer 2x4, no notches, like the first people I saw looked a bit easier to put together and walk on cuz not so steep have u tried that one??
Love it. Getting ready to do a full size one for our first school Maker Faire in Perth Ontario Canada. HOw long are the 2x4s? they look like 4'? ALso save time by drilling 2 half holes at once?. Save $$$ by using 2x2 rather than dowel. I find dowel always seems to more expensive than I think it should be and you have to use a fair amount. what was the length of the dowel? it also looks like about 4" Thanks so much
Peter McCracken, have fun with it. Yes, we cut 8 ft 2x4 into 4 ft. I imagine 2x2 could work as a dowel replacement, and would save you money for sure. We planned on using 2 ft dowel, but ended up leaving them as 4 ft just to make the project go a little faster. Also allowed is to make the bridge a bit wider.
HeyDadHey Thanks for getting back to me. We had a go at the bridge and it worked out great. 4' 2x4s. For the dowels I ripped 2x4s to 1.5x1.5 then ripped off the corners so I ended up with an octagonal dowel. Just have to carefully select material as one large knot in the wrong place will compromise the dowel
For a dowel replacement, I used 2 X 2 and 1/2 inch deep dados. Can support my weight, 190 pounds. Might also make 1/2 plywood platforms to make it easier for the younger ones to cross.
j'aime beaucoup Leonard de Vinci mais ... ce type de pont dit "arc-en-ciel" est un type de pont en bois conçu en Chine sous la dynastie des Songs entre 960 et 1279.
"pont arc-en-ciel", merci beaucoup, je m'en souviendrai. "Rainbow Bridge," thank you very much, I will remember that. (and thanks google translate,) he says he likes Da Vinci, but this is called the "Rainbow," built by the Chinese Song Dynasty about 960 to 1279.
It's not symmetric because you started at one end and built in one direction. If you had put the center down and alternately built in both directions it would have come out more symmetrical and not as tall.
Alex Jaensson Thanks so much! Trying to gain some traction, just need to keep putting the content out there I suppose. Be sure to share us with people you know would like our videos!
Was ever used years ago when Leonard was alive or just a design like the flying suits of today that at least one person died recently yours Evans w Robinson
I admit it works in the small scale, but can you imagine trying this over a river? While his notebook has beautiful drawings, he is given far too much credit as an inventor. So many of his ideas would be extremely impractical in the real world.
Good video!

First I thought I thought you had 62 K subs but then I noticed it was only 62. I think your channel is worth 62 K subs

yes he is so good
Awesome to see people excited about anything Da Vinci. He is definitely one of my very favorites!!
Awesome to learn about, for sure.

Try alternating between inside outside on each section you assemble. The friction will help with stability and you'll have a more balanced base.
What a cool project guys. I will have to do that this summer with my Grandson. That you for posting.
This channel is so underrated
Your channel is worth like 5 million subscribers (heck even more) I love this 💙!!
I like what you are doing with your son! Just got another subscriber. I'm looking forward to seeing more videos.
Great job! You nailed it! (Oh, wait!)
So cute hahahaha

Great video man!
You can add side poles for grip and balance.

Fantastic! Great job on the bridge and video too.

Great artist? One of the smartest human beings in the history of mankind.
I'm going to attempt this! But I have one question...how far away from the end of the 2x4 did you drill each of those notches??
doesn't matter as long as it's constant
MAKE ANOTHER VIDEO!!! THIS IS LIT💯🔥
Great replica! Love it!
Fantastic!

Can you tell me how long is the side pick length?

Excellent!☺️
Can you put the lengthwise pieces inside and outside alternately for a more even design?
Yes.
Would I be right in thinking that the bridge is narrower at the end you start from (left hand in the video) & wider at the end you finish with (right hand in the video)?
The lengthwise pieces should be put inside/outside alternately for an even design.
Hi, was just wondering what the dimensions were for this build? Thinking of making one
I wonder would bamboo work and have a bigger arch, and have maybe three joined side by side,then cover it all with netting to keep the birds off strawberries and cabbages. You could tie the canes with plastic ties. This has great potential with gardening ideas.

Great video and channel, I would love to see more contents here
Good job u and ur son did together.. Always nice doing stuff like that together. Longer 2x4, no notches, like the first people I saw looked a bit easier to put together and walk on cuz not so steep have u tried that one??
Imma build a friction house. Challenge accepted. Slight wind breeze get out of my way.
Can it be less steep?

Adds a little work, but can save you a couple of dollars per dowel for sure. Good job!

But what about the decking ?
you deserve many more subs!

inspiring-- thanks!
great video
Great job men..
Keep up the good work.
"stay focused on Jesus my friends"
You Guys are getting a sub!
great perfect for a scout troop and lash the rail pieces and it will last
Wow! So eine schöne Liebe! (such a beautiful love?!)
the problem with davincis bridge is you cant build it from one end
# johnny llooddte ... no true ... this chap shows how to make & assemble (th-cam.com/video/QJWWriECrEI/w-d-xo.html)
Wow, this has more likes than he has subs
Good job, but it looks a bit steep.
good channel
Your bridge needs a davinci hand rail as well.
Let's teach this kid about the Renaissance. First up, get a bunch of wood from home Depot and notch out a groove with your router...
"traditional" Chinese wooden arch bridge, De vinci stole the idea
Was ever used years ago when Leonard was alive or just a design like the flying suits of today that at least one person died recently yours Evans w Robinson
O wowww 🤩
Not the most practical bridge though is it.Very difficult walk over or get your horse or donkey over. Plus limited by the span.
I want to build the one the car drove over...
There are many similar projects in Woodprix's plans.
ahahahahhaha..even a child can figure it out... good job
da vinky
i thought the chinese build wooden bridges like that way before ol da vince was born???? just askin....
I admit it works in the small scale, but can you imagine trying this over a river? While his notebook has beautiful drawings, he is given far too much credit as an inventor. So many of his ideas would be extremely impractical in the real world.
Kto od 5 sposobów na?
Just google Stodoys and make some dust.
what has happened to kids? will you hold my hand, i dont want to fall from a 3 ft drop....
I'm just glad he has a dad that will hold his hand.
