Free 2v geodesic dome plans using WangerFlanges

[@tobygarratt6032]

I’ve just finished making this dome. Took me a day to chop the timber, get the wangers on the struts and build it. Goes together really easy and it’s very very strong when all the nuts are right. Fantastic work from Paul making this possible

[@Geo-Dome]

Fantastic! What cover material are you thinking of using?

[@tobygarratt6032]

Paul Robinson I was going to fill most of the sections in with wood and cover with felt and use 5mm acrylic sheet for windows

[@pjamesbda]

Some clever lads 'cross the pond...thanks for your efforts. You're the best.

[@ceili]

Thanks Paul, really appreciate these videos

[@chrisk7118]

Cheers for sharing! Really great design.

[@jimginnyohio]

Very nice!

[@akespt]

Awesome. Thank you! One step closer to cabin with a more solid covering.

[@Geo-Dome]

Glad it helped! I'll be posting more info about hard covering shortly

[@davidfuller764]

Thanks so much! Very slick design.

[@davidfuller764]

Heck of a lot of information here sir Paul, thanks, time too order 200 more wangers. I really like this 2v plan!

[@akio2k0]

Thank you so much

[@fraserstewart7359]

Hey paul. Great video. Nice clear and concise work. I wondered if you could expand on what type of canvas you are describing. Is it possible to wax the canvas for waterproofing. Would love to hear what you use

[@bwillan]

These plans are fantastic. One thing I noted was the lack of information for scaling the green strut for the half triangles along the base. I am sure I could figure it out, but it would have been nice to include the information in the plans. For the door frame, would a piece of 19mm plywood cut to dimensions work too?

[@bwillan]

After watching the video again, Paul did mention that he would be doing additional plans and details for various size 2V domes from 3m on up in half meter increments later.

[@Geo-Dome]

@@bwillan Yes, I will be but of you want to know for now the green strut is half then length of a yellow one and you only have to take off 55mm for a wangerflange on one end.

[@thegeniusofthecrowd354]

I'd be interested in a design ideas for the "fish scale" tessellating geodesic covering on the Dome of Visions dome in Copenhagen that's bolted together. The design is supposed to be a closely guarded secret. Any thoughts would be great. Cheers Paul.

[@Geo-Dome]

Sure, what diameter where you thinking? I'm doing some work on domes just made with polycarbonate sheet like hexadomes. sounds very similar, get back to me with a diameter and preferred scale size and I'll work something out

[@ronphillips379]

Great...

[@dougcolter5222]

Thanks Paul big fan of your work. I am thinking of making a child climbing Dome. Thinking of making it out of three-quarter inch EMT. I'm wondering how I might be able to add on to it in the future to make it taller as she grows

[@JohnGuest45]

Make a 3v frame and add an extra row of triiangles at the bottom to increase the height when needed.

[@Geo-Dome]

Great idea, I am planning on doing a full project book full of climbing frames, You can build something a completely different shape if you want using the same parts. I'll try and get some work done on this shortly so keep an eye on new videos, however it may be a week or so as I'm super busy!

[@NinjaDeathTeddy]

Hi Paul Any way I could build this out of bamboo? Is it possible to deconstruct, move and reconstruct ?

[@jonzahon1652]

Paul . these videos are just great. But trying to get my head around , Why are there a few pentagons in geodesic domes ? Would it be just easier to make the whole thing out of hexagons, and make the next higher level triangles a bit smaller, to get the curve? thanks

[@mrnobodynobody.]

You need 250 wanger flanger connectors in this build it cost 350£ thats 380€ + bolts +- 100 ,its just doesn't cut with expectations of someone who is into affordable living. In my country timber 50*50 is 1 euro to build 3v dome 5m wide i need 168 meters of it so its 170€ timber 40€ screws 210€ in total for higher frequency dome made in bevel or "good carma" method all included.

[@romandecaesar4782]

Hi Paul. Would like to know if you can convert the plans for this into imperial measurements. Also, when will the hardware be available for purchase (nuts, bolts, etc.)?

[@johnmanders5712]

Ad what angle to cut the wood

[@SenatorPerry]

Do you have a link to the 250 WangerFlanges package? I only see 150, 100, 50, and 25 (I live in the US).

[@bwillan]

There's the motherload option in the big cartel store, which is currently listed at £1000.00, but doesn't list a quantity. A 250 pack around £300.00 mark would be quite nice.

[@JohnGuest45]

@@bwillan The 250 pack is £350, not worth it for a 2v

[@Geo-Dome]

Yes, it's called the trolley load you can purchase 250 here: thewangerflangecompany.bigcartel.com/product/trolley-load-of-wangerflanges

[@bwillan]

@@JohnGuest45 WangerFlanges aren't the only method for geodesic dome hub connection.

[@SenatorPerry]

The 150 and 100 combination is cheaper than the 250. Looking forward to ordering. Went to Lowes here in the US and they had no lumber. :-/

[@josenaraval6749]

Great post as always Paul! I was about to ask you in one of your previous videos as to how many wanger flanges needed for the 2v. Anyway, got a quick look in the plan and you use struts that is roughly 2” (49 mm) but did not specify the height. What is the maximum strut height suitable for this construction? Would 2” x 6” work or you would only recommend a 2” x 2” strut for this. Thanks!

[@JohnGuest45]

Its not worth using 2x6`s. With the fixing screws centered at each end, the strut is free to rotate when subject to torsional moments. A WF dome is essentially constructed of square rollers. Most geodesic hubs are designed to transfer torsional moments so the struts cant rotate. You can solve it by using 2 sets of brackets per 2x6 but then you may as well use tubular hubs, its about the same amount of work and vastly cheaper.

[@stongeQc]

Hey Paul. I haven't receive an anwser from my emails to your email from your website. I try here. I woubl like to buy the plans for a 2v beveld dome. Cant seem to find one on your site. Coubl you arrange something so I can get them. Thanks

[@alexanderedward9059]

Do you ship to the US

[@angetodac]

where u can buy the wanger flanges: how many do we need for this model?

[@Berkana]

At 2:00 the video says you need 242 flanges. It also says he sells a package of 250. The site where you can buy the flanges is this: thewangerflangecompany.bigcartel.com/

[@Geo-Dome]

You can buy them by following the link here: www.wangerflange.com

[@alexanderedward9059]

Do you ship to the US rite now?

@@Geo-Dome saw it, thanks.

[@flipemntalvo806]

wath is the red struts size?, thanks a lot

[@marceldupont3756]

Hi Paul great Works Again ! And fantastic idea the middle line ! Do you think it would be auto stable half dôme ? The idea would be to have two half dome, one smaller the upper one and so that would create openable dome ??? With pivot at the base common point between the two half dome. I am looking for a pool cover. Regards i hope but afraid not readind you facing your success.

[@Geo-Dome]

No, unless you have something attached to all the struts around the edge to give it stiffness they would distort or wobble a good bit. It's a great idea the opening eye thing but engineering it is a challenge, it might be possible with truss system, I'll have a think about it

[@Geo-Dome]

Next video is of a trussed 3v dome and could work for what you need,

[@marceldupont3756]

Hi Mr Robinson It is really a pleasure to read you ! And an honor, i am really impressed your knowledge since the begining i follow you. If my idea is a track for you i am very happy ! People have more and more pool and above all this year...+400 %...that a crazy and worry news about ecology...but it is like that....à pool house or « dome Help you reduce chimistry and keep clean your water so solve pump time so we can Say is a little bit better... And it allow also child to swim more often in lot of unsunny place So to resume :pool is a lot non ecology think but as far as i would like to take care environment i need a efficient cover! And it s really going to be a business so get ready That why i think geodome ! Your last video is a wonderful idea to permit openable dome with pivot or translation half dôme. in my case, I am just afraid the amount of wanger in trussed dome I hope to read you again maybe with news about this project Thanks again Regards

[@neilreynolds4799]

Hoping for a reasonably simple answer... I've tried looking round your site and done all sorts of searches on the web but can't find details of the dihedral angles on this structure. I see them for 3v, but that doesn't help here. If it's to be clad in ply then I need the angles for the bevels to cut the sheets so that they butt up against each other properly. I know that I should be able to work them out with some trig, but I'm struggling as to how to start. Clearly I need a maths revision! I assume that it's reasonable to clad with ply when using the wangerflanges. If not then I'll need to use bevel frame, which will still need the dihedral angles. Would be grateful if anyone can help.

[@Geo-Dome]

You're right there isn't much on the web, if you use this calculator: geo-dome.co.uk/2v_tool.asp Dihedral angles for red strut is 157.5° Blue struts are 162° Making bevel angles of 11.25° (red) and 9° Blue. Hope this helps. I have changed geometry on my own plans to 10° for all struts but you have to use measurements from the plans for this to work.

[@neilreynolds4799]

@@Geo-Dome Thank you very much for both the answer I was looking for and the speed of response. I just need to get the planning permission now... from the family, not from the local authority!

[@neilreynolds4799]

@@Geo-Dome Reading your response again you talk of your plans. Are you referring to the 2v with wangerflanges in this video, or a 2v bevel frame plan. If the latter then please can you direct me to it as I'm happy to buy it, but couldn't see one that was described as a basic half dome 2v. That would then enable me to decide on either bevel frame or using the dimensions on that plan then reducing by 110mm and using wangerflanges. But it would make the cutting of the bevels far easier if they were all the same!
