I have been building these for years . A few things I have learned .the chord length will deflect a maximum of 1/6 of itself. That is a 12 foot length will support an arch that is 2 feet deep,soaking the material in water or hot water aids in its flexibility. Wet wood can be glued with urethane construction adhesive, it sets with water. Rather than pulling a curve onto horizontally placed blocks, it uses less material and is more efficient to push the form down into risers that form the curve. I fix my blocks onto the top chord glue and air staples then push it down into the vertical risers tacking here and there with screws,no clamping necessary, then apply glue to blocks and push the inner chord down onto that assembling the truss with air construction staples. Undoing the tack screws it pops from the jig . You can expect 10 % spring back. I layout the curve as a catenary arch. This I found is the simplest tech , I could never understand the massive area and sport to construct horizontal platforms and blocking and clamps etc. A vertical form requires no platforming and can be as simple as hammering stakes in the ground.. for planning select three points one midpoint offset by 1/6 and drape a chain connecting the three, the curve formed is the layout of a catenary arch . Plan using scale grid paper transfer the measure and angles to stakes ,vertical risers, miter the tops and the form is ready to press your trusses.
If someone can school me on how post a jpeg , I would commit the whole process to a graphic that would clarify the concept. I am elderly and haven't got to posting videos it's above my pay grade right now.
@@paulhayes9832 Hi Paul. For the 10% spring back, do you adjust for this when setting your stakes or do you set them normally and accept the spring back as the finished product? Thanks.
I like the simplicity of this design. It can be applied to an actual home as well. Perhaps instead of the two curved pieces you could use this to make a dome roof. And instead of a tent, you can add read walls and have a real home.
The problem is that its flexibility is its strength. It would have to be made very rigid. I was thinking that the bows could be laminated in a mould from plywood. Then purlins and cedar shingles on the outside, but the bows would have to be very chunky.
I think metal-corrugated sheets would work great... If you ask an engineer, they would tell you that a pole building gets most of it lateral (shear) strength from the metal wall panels. So metal panels on this arched structure would replace the 1x diagonal bracing. Perhaps the real question is: how much the wooden arches would flatten out with the weight of the metal wall panels. I think use 29-gauge max steel thickness. The best way to prevent the arches from squatting down is to use a load-bearing ridge beam (that is supported at the ends with door headers in the endwalls). Another good way to prevent the arches from squatting down is to have relatively tall arches compared to the width of the arch-base. Use best practices for gluing/nailing the wood blocks in each truss. Finally, if you are still feeling conservative, you could tighten up the typical arch spacing. Don't mind me, I still have hopes to build my first boat shed.
@@moldprintsrl I think that these arched sheds (with plastic or vinyl covering) are prone to collapse from "unbalanced snow-load"... so be careful about having snow drifts on one side of the building and not the other... With local knowledge and awareness of snow drifting (and snow melting cycles), you should orient the axis of your building to minimize "unbalanced snow-load" or "unbalanced snow-drifting". @Stran I , if you have snow loads (or snow drifting) in your area, DO NOT BE TEMPTED TO USE RIPPED STRIPS OF PLYWOOD FOR THE ARCH CHORD MEMBERS. If you use metal roof panels over wood arches, pay attention to condensation on the interior of the shed (you might need to ventilate or heat the space).... If you have excessive condensation, then your wood arches may not last as long as the metal roof panels. @stran I , If I were building one of these arch sheds, and if I was planning to "skin" the shed with metal roof panels, then I would really think about up-sizing the interior chord-members (of each arch) to a 1x6 (or a rough-cut 1x6, or maybe a double 1x4).... (the outer chord-members are less important if you are using metal roof panels).... The reason is that: 1) the metal panels will provide some arching action across the full-width of the shed (acting in compression to strengthen the arch for dead loads or snow loads), and 2) the metal panels will provide some bending strength (metal panels acting again in compression) for each half-arch which spans from the footing to the ridge...But the half-arches ought to be strengthened in bending by up-sizing (or sistering) the interior chord-members to a 1x6 (or a rough-cut 1x6, or maybe using a double 1x4 for the interior chord-members).... Note: these interior chord-members would be acting in Tension when the half-arches are working in bending. Strengthening the half-arches in bending will provide resistance to wind-loads, and provide resistance to unbalanced snow loads....... If you have a "skin" that can deliver wind loads or snow loads to the half-arches.
If you get heavy lorry tarp it should last for 5 to 10 years. The shape of the tend spreads the load nicely so there isn't much chafe. I got the tarp manufacturers to put a double thickness strip on the ridge area though. Hope this answers your question. Cheers, Tim
So you didn't glue the spacers? Just screwed? Seems like it if you could build one of the bow / arches every 15 mins.....I will be building one for my project and not having to wait for glue to dry will save a lot of time...
I would like to purchase this project, but unfortunately, I do not have the resources to buy it. If any of you have a detailed 3D model of this project and are willing to share it, I would be very grateful. Buying the project is currently beyond my means, so I am forced to design it myself. However, due to a lack of experience in design, I make many mistakes and progress slowly. I promise to share a portion of the profits with those who help me with a detailed 3D model after successfully implementing my project.

Planning permission? Easier to ask forgiveness than permission! Get proof of the date of construction. There's often a period (5years - look it up) and if they haven't noticed and nobody has complained you get to apply for exemption. But you will probably need to get structural certification before they'll exempt you.
What in the hell boatyard let you put in concrete pilings and spread gravel????????????? In upper ubangi-bangi somewhere in east Africa, I can understand, but in the UK?????
Came for the tent. Stayed for the music.
Me too. Awesome!
Man... i barely made it through the video due to the music. :D
Great video, great shed, and great sound track!
yea man what is that music awesome
I love this. Great work, y'all.
It's beautiful and reminds me of early 1900's aircraft construction.
amazing!! Best video I've seen of a bow roofed shed construction!
Spetacular vídeo. Congratulation from Brazil...😅😅😅
That! Is a very beautiful and fitting piece of architecture. It will be a shame to ever dismantle it.
Dig the music, goes with the humour.
Great job already with the shed. Looking forward to seeing you guys get to work on the boat.

Great job. I really enjoyed the music, can you tell me the names of the groups and the song titles please.

Perfect job!
if you put some nails in 1/2 way into the posts the concrete will make a solid connection.

would it be a long lasting shed / garage if covered with metal corrugated sheets ? need something similar for a large tractor
It would flex too much I think

I'm I the only one who liked that sound track? What is it? Where can I find it? Anyone...
Hi? Great video! Quick question please? How this fabric material is called and how thick is it? I am thinking to build the same one. thanks
Not sure what he's used. But my research led me to the search term "film" as in White Polyethylene Film.. As used in the greenhouse industry.
@@M3rVsT4Hthanks man
Heavy duty lorry tarp, 600 gsm. It was the biggest expense of the whole build but worth it.

You would have to have an engineer stamp for this in Canada.

Interesting, just wondering why you thought you needed to add the intrusive sound track - just because you can doesn't mean you have to!
Perhaps because on top of being efficiently great builders, they also have good taste in music and video production.
@@Ranchohieloyfuego But I watched it to see the build, not chill out to the sound of reggae!

What is the D4 glue that you used? Is it a pva or urathane single part glue? Did you glue the arches as well?
It’s PVA. I didn’t glue the arches, but I could have/should have done.
@@seaschool_ Unfortunately I found out it is not available in the states.
