Great tutorial. Of all the various geodome methods & approaches, I think you’ve really honed in on the simplest, tightest tolerance, most reproducible options possible. Have you considered making & selling the required jig sets for your designs? There is real value in accurate jigs & tools - easier to send out sets of jigs rather than full frame sets!!
I use cheap Dollar Store, Extra Hold Hair Spray on my Wood Jigs. The holding property of Hair Spray consists of "water-soluble-plastic"; by misting the wood mold with two or three coats of Hair Spray, we are effectively removing the surface tension between the part and mold, allowing for easy release.
If I understand correct than I have to cut the top of the basement part "A" in an angle of 12° on the top. But how about the parts "B" and "C": Do the sloped base sections also have a top with a 12° or not?
Yes there is a bevel all the way round the outside of the triangle frame, freeze frame it at 0:16 and you can just see it. The frame is square on the inside and has the bevel on the outside. Hope this helps
What are the angles of the end view of the beams? Is the bevel on the outside length of the "A" beam different from the bevel on the outside lengthof the "B" beam?
You have the best method, easy, economical and beautiful. My two cents of suggestion is the timbers in the triangle of the jig can be about 2 inches short of the corners, making it easier to build the jig. Do you think that will work? I really want to build a dome in my back yard. I don't know what for, but i think it will look good.
I'm easily confused but, if you bevel the struts only once, how do you end up with sides also beveled? Following your video, they should be perpendicular but they aren't. Very baffled old lady here! :)
At the beginning of the video, you show prepared boards are cut along an angle. In my calculations, 10.8 degrees, which angle of inclination of the board have?
+MARK M It depends on the frequency, a 2v has 10 degrees, a 3v has some 5.5 and some 7 degrees ( I adjusted the geometry to make them all 6.5 degrees) and a 4v has a 5 degree bevel approximately. I have a calculation tool here: geo-dome.co.uk/3v_tool.asp that show the angles at the bottom of the page, to get the bevel angle you need to divide by 2 and take away from 90. (166 dihedral is 166/2 = 83 then 90 -83 = 7 degrees bevel) Hope this helps
+Paul Roinson Thank you, it really helps me. I use a program of 3D modeling for the calculations. I want to build a workshop, a 4.5m radius of the dome.
The 3v uses 3 unique dihedral angles, the pentagon triangles use 4.13 and 7.22 degrees, the hexagon triangles use 6.79 and 7.23 degrees. Adjusting the geometry to make everything 6.5 degrees isnt mathematically possible. You are simply trading accuracy for ease of construction.
Yes you are correct to say that it is mathematically impossible, however in a manufacturing environment we use tolerances, if you ask an engineer to produce a component accurately they'll just ask how accurately? So with that in mind how accurate is the average DIY dome builder likely to be.... Cutting bevels to within + - 0.5 degrees is probably the best we can hope for but some may not even manage that, so it's far more important to have a build system that can tolerate some error. The build method I use doesn't have large section timbers so it could probably handle + - 2° and still go together. I don't think that the dome builders here: czcams.com/video/kILxlKIri7o/video.html care about accuracy they just want a simple system, that's what I provide.
brilliant info thanx... i still cant work out if one of the timber pieces from the frame is slanted how your able to turn it round and still fit.. bugs me... any info on that??
Yes, 6.5° down all of the struts, just remember to make this as accurate as you can, I assume it's the geo-dome 3v you are building because other domes will have a different angle. Hope this helps
Paul Robinson how do u get 6.5 degrees on a table saw mine wont go that flat and idk if my plans are missing a page or what it seems like there should be more info for someone that aint real smart like me
What happened between 2:30 - 2:35? All of a sudden, an inner frame appeared! Is that your template? Is it beveled? How is it attached to the plywood underneath?
He skipped the step of aligning boards inside the clamped beveled pieces he set on his triangle. The inner frame is the template. An important step to skip... For example, how did he cut the inner frame so perfectly? I assume he had to measure the angle and cut both boards ahead of time, which is the opposite way he's suggesting we build the struts later.
no shit bro .... im sitting here watching and feeling sick !! the second i thought " man this sucks ! i feel sea sick !! " i look down to see your comment !
Sorry about that, I am still in business just crazy busy. If the first email goes to spam all the others follow so maybe that's it. try Paul(at)geo-dome(dot)net
Sorry about that, you simply glue a square bit of wood behind the frame, this makes the jig. When you screw together and take off the first frame the next one buts up to the square timber so you can make another frame exactly the same size as the first one.
Paul, I love your homey workshop space. You are obviously a man who makes the best with what he's got. Good on you.

What is the angle of the bevel you ripped on the molding?
nice, i like it, do you have the plans
respect 2 master 8-)
Nice and good idear
Paul, I would like to purchase a set of plans but the website seems to be not working. Any tips??
Do you have a link to the plan like you said on the Video cause I can't find it
Yes there is a bevel all the way round the outside of the triangle frame, freeze frame it at 0:16 and you can just see it. The frame is square on the inside and has the bevel on the outside. Hope this helps
What are the angles of that end view? Is the angle on the length of the "A" beam and "B" beam different?

Is the molding itself beveled? That would answer my other question......I think lol

Paul Robinson I’m wondering which angle a 1v would have? How do I figure it out?
brilliant info thanx...
i still cant work out if one of the timber pieces from the frame is slanted how your able to turn it round and still fit.. bugs me... any info on that??
the slant is at the outside
Hi Paul want to build a geodome 2v 12 feet wide for my wife can you tell me the 2’size a jig i need and the angle thank you
Are you making the 6.5 degree bevel by ripping it on a table saw?
Yes, 6.5° down all of the struts, just remember to make this as accurate as you can, I assume it's the geo-dome 3v you are building because other domes will have a different angle. Hope this helps
thanks.
I'm building the gd15 4.5 meter.

@@brianwhelan92 And what angles should be for 2V? thank

I purchased you GD15 plans, but there is no mention of what angle to bevel the molding. Help!
Hi Jon, it's on page 4 Look for the frame cross section drawing. If you still have trouble drop me an email and I'll send another drawing.
I had the same problem, i actually cut all the wood to a 12 degree angle and was wondering why the triangles didnt fit together ...
@@Geo-Dome Cześć. Chciałbym kupić u Ciebie plany kopuły, jak to zrobić?
Nice, but I'm sea sick with all the camera swishing,
no shit bro .... im sitting here watching and feeling sick !! the second i thought " man this sucks ! i feel sea sick !! " i look down to see your comment !
I'm drunken now from viewing :) :)
Bonjour aurais tu le.plans conception ?
I have asked several times if this company is in business or not for plans, never an answer, does anyone know?
Sorry about that, I am still in business just crazy busy. If the first email goes to spam all the others follow so maybe that's it. try Paul(at)geo-dome(dot)net
bad camera positioning and absence of microphone make the overall bad impression. But the content is amazing.
What happened between 2:31 and 2:34? All of a sudden, an extra frame materialized, and you did NOT explain how it was attached!
Sorry about that, you simply glue a square bit of wood behind the frame, this makes the jig. When you screw together and take off the first frame the next one buts up to the square timber so you can make another frame exactly the same size as the first one.
