Thank you so much for getting back with me and I will take your advice:) We will be stuccoing the outside with a hemp and lime mix and plastering inside. I am working with Loveland hemp company who built the first permitted home in Colorado. Will post some video. Thanks for putting yours up for us to reference
Hey, that dome looks really strong. With using wood struts made from 2x4s do you think a 2v is strong enough to handle a snow load? Another great video, Thanks.
Is that miter saw as accurate as what everyone says it is. I'm wanting to build a dome usin no hubs and didn't know if I should save to get one like yours first.
hey there, how many base boards did you use for your 18ft 2v dome? I assume 12 ? I'm building a 15ft diameter 2v dome and it looks like I need 9 or 10 base boards. I just finished all my cuts, I'm about to construct
Need to confirm that your reference to strut B is the 35 struts with the 60 degree arrowhead cuts. Some sites have it switched. Thanks for doing the videos.
All the 2V domes on simply differently use 10 base boards regardless of diameter size. The only thing that would change is the length of the struts. Good luck with the build. At 15 feet you shouldn't have any problems. That's a very manageable size.
A duel angle miter saw is definitely a huge plus in cutting the angles. I only have experience with this particular saw so I can't compare it to other duel angle saws, but this one worked very well.
I purchased Kacpers book as well and he revers to purchase a dual angle miter saw. Is this the same as a dual bevel ? I assume so but wanted to make sure.
Oh, sorry about that. Well, it was leftover wood from the 40 foot dome but I think it is around 115 meters. If you use the dome calculator at simply differently then you just need to plug in your diameter and take each strut length and multiply the number needed.
We are building a 20' geodesic hemp dome this weekend June 4th. I am curious about what went wrong the first time so we can avoid making the same mistake. Thanks for any advice you can share.
A hemp dome sounds awesome. Will you stucco it? What type of flooring? Our 40 foot dome that failed to close was not level at the base so we weren't able to meet the top pieces up. Our smaller 2V dome closed easily probably because it is smaller and we were able to nudge it into shape. With your 20 footer, I would say get it as level as possible. I wouldn't get obsessive with it but the more level it is, the easier it will be to join at the top. Good luck with yours.
OMG this is a very helpful video along with the ones for the 3v dome, I am doing research to build my first dome. it will be a 2V dome, 12 ft diameter.
Great job. If I had to figure out those cut angles, My head would explode. That's alright, I've been in E.O.D. my. Entire life. I have hubs already and am using tubing. It's from a kids playground- a 2v Dome. So I am tripling the strut sizes and only using the hubs. Problem is setting up the bottom on a 45° mountain side. So it's flush to the ground at top and 6 or 7 feet up on the bottom .Getting level and getting the spacing of the posts its gonna sit on is drivin me nuts. Anyway, great work! Wulfy
Please what is the diameter of this nice dome ? (but very difficult to disassembly at the time to move ..). And your struts, 2x4 ? Thank you very much.
I would say yes as long as you are using this type of connections. I'm unsure of the strength when using metal hubs although Rob at web4deb did a huge hub dome and he's in the northern U.S. I know he gets snow. The geodesic dome, popularized by Scientist Buckminster Fuller in the Mid 20th century, is the strongest structure known to mankind. I did cheat a little as the plans I've been following say to go 3V if you build larger than 15 feet but you're right, this 18 footer 2V is very solid!
You can get plans at biodomerevolution.com. They have actually upgraded the dome and now use a hub system which looks to be way more efficient and easier to build.
I don't think it would really save that much time and doing each one as it came up allowed us to adjust where we put the holes. The screws cross each other and we hit a previous screw on a few occasions.
I wonder if it was a one man job. Structureing the dome from top to bottom would be easier. you would need a pole with a pulley system. so as you build levels use the pulley to raise up your finished work and complete without climbing on it. Nice work though
Basically, it is the frequency meaning the number of triangles. A 2V only has 2 size triangles. The higher the number, the more triangles of different sizes you have which means a larger number of different angle cuts on your boards.
It doesn't really need to be any stronger. The glue would be overkill. The geodesic dome is the strongest shape on earth. It is self supporting at each joint.
Yannan Zhao It depends on how big of a dome you build. We used the dome calculator at simply differently dot org. You just put in your desired size and the calculator gives you everything you need.
Walt Lars We used the dome calculator at simply differently dot org. You just put in your desired size and the calculator gives you everything you need.
There are two angles cut on each board. It depends what size and frequency dome you build. You can find the angles using an online dome calculator. We used the one on simplydifferenty.org.
@@bruhmania7359 In the calculator where it says edges/struts & bending angles, the number in parenthesis is the angle. Using the 2V as an example, the " A x 30: 0.54653 (15.86) means you will need 30 boards cut with an 15.86 degree cut on each end and 35 boards cut with 18 degree angles. Underneath that where it says "A lath= and B lath=" is the length of the struts in meters. 30 "A" struts at 2.1861 meters and 35 "B" struts 2.4721 meters. Just use a meter to feet converter to get the measurements in feet.
There are multiple duel angles that need to be cut. The angles vary depending the frequency of the dome. (ie 2V or 3V etc) You can use an online dome calculator to get the angles. I used the calculator on Simplydifferently.org to get mine.
@@ThomasAkaK Interesting. Those zomes look pretty complex especially if you triangulate them which you would need to do to make them stable enough in my opinion. Sorry, I don't have any info on them.

Nice. thanks for the upload. your dome is a project in my future.
Is that miter saw as accurate as what everyone says it is. I'm wanting to build a dome usin no hubs and didn't know if I should save to get one like yours first.
Thanks so how did you cut your 60 degree cuts ? Every saw I see has max of 45-50

Did you cut the sides on a beveled angle?
@@aleva898 yes, duel angles
I purchased Kacpers book as well and he revers to purchase a dual angle miter saw. Is this the same as a dual bevel ? I assume so but wanted to make sure.

Going big!! Yeah!!
All the A struts get the same base angle cut. The arrowhead cuts are when you need to put a different cut on each side.
i like the joint union...
not like very small amount of material around fastners..could add a v block incorners

Wow, that does sound tricky. Hope it works out for you. Sounds sweet.
kool
how cutting angle cone ?
Saw in the background a plastic covered structure with a door in it. Would you please tell how you went about framing the door opening?

Thank you, sir! Many are the construction vids of a dome, but almost none at all about how you get in and out! :D
muito bom valeu
Please what is the diameter of this nice dome ? (but very difficult to disassembly at the time to move ..). And your struts, 2x4 ? Thank you very much.
+Quaoar Angela The diameter is 16 feet ( 5 meters) and the struts are 2 X 4.
I would say yes as long as you are using this type of connections. I'm unsure of the strength when using metal hubs although Rob at web4deb did a huge hub dome and he's in the northern U.S. I know he gets snow.

Monolithic dome should be stronger than a geodesic dome.
If you mean what size is the dome, it's 6 meters in diameter.
Now the challenge becomes putting some polycarbonate on there
Great job may I ask where you got your plans from or do you have directions that can be bought thanks for sharing

Thanks for sharing keep it up
la tecnica del cono ?
I don't think it would really save that much time and doing each one as it came up allowed us to adjust where we put the holes. The screws cross each other and we hit a previous screw on a few occasions.
How did you figure out the angle on the pointed end where the hubs screw togther I'm using 1x3 for a small dome
We used the dome calculator on simplydifferently.com. Under the dome calculator tab you put in your dimensions and it will calculate all your angles
I wonder if it was a one man job. Structureing the dome from top to bottom would be easier. you would need a pole with a pulley system. so as you build levels use the pulley to raise up your finished work and complete without climbing on it. Nice work though
So what are the finale conclusions
How do you ensure the screws don’t hit each other?
Just by aiming carefully. I think we only hit a screw a couple of times out of all the screws we put in.
hi! what's the length of the screws you used??
2 1/2 inch
how i do calculate the angles to cut struds?
We used the online dome calculator at simplydifferently.org
What do yhey by " V". Whats the diff 2v, 3v, 4v a d 5v?
Basically, it is the frequency meaning the number of triangles. A 2V only has 2 size triangles. The higher the number, the more triangles of different sizes you have which means a larger number of different angle cuts on your boards.
Why not using glue as well as screws ? Would have been much stronger. Very Nice build anyhow! Something to be proud of !
It doesn't really need to be any stronger. The glue would be overkill. The geodesic dome is the strongest shape on earth. It is self supporting at each joint.
How long is the A pieces and how long is the B pieces???
Yannan Zhao It depends on how big of a dome you build. We used the dome calculator at simply differently dot org. You just put in your desired size and the calculator gives you everything you need.
Can u explain how to build it
Do You have a list of the angles and miters that You cut the wood at ?
Walt Lars We used the dome calculator at simply differently dot org. You just put in your desired size and the calculator gives you everything you need.
Cool beans !
That website doesn't exist anymore... is there another you recommend?
It is still there and working. "simply differently dot org"
How do you know what angle to cut the 2x4’s at?
There are two angles cut on each board. It depends what size and frequency dome you build. You can find the angles using an online dome calculator. We used the one on simplydifferenty.org.
@@ghog63 okay thank you! :) subscribed.

You are saying nothing of the angles and bevels which is the info most people would be looking for.
