Growing as much food on as little land for as little money as possible

Geodesic Dome build. Pentagon template, triangles and panel.


As you have seen in the previous post I have completed the first of the Hexagon panels so the next step was to complete a Pentagon panel so I could be sure they would go together before forging on and making the rest of the triangles.

There are only 6 Pentagon panels to make and now I know they work and everything fits together and my two chop saws are set to the Pentagon angles I will press on over the next week or so and make all of the pent triangles.

Here is a picture of the two jigs needed for building this dome. The tall one is for Hex triangles, the other is for Pent triangles.

Hex and Pent Templates

Making the triangles is simple once you have the templates built and checked for accuracy. You start by cutting the correct angles on one end of each of the struts. then you clamp the struts to the template and screw the struts to each other and saw the projecting ends off.

I will add a photo of this later.

As I am finishing each triangle and before I take it off the template I mark the apex of the triangle as this makes it fool proof when assembling the panels.

Here is a picture of the finished Hex and Pent panels before putting them together to test their fit.

Hex and Pent Panes

You wouldn’t normally make the panels up like this before covering in plastic but as this is the first dome I have built I wanted to make sure everything lined up and the two panels fitted together.

Here is a picture of the Hex and Pent panels fitted together.

Hex and Pent Panels fitted together with Jules providing some scale.

To give you an idea of the hight of the finished dome there is another Hex panel to go below the Hex panel in the above picture. The picture above does illustrate the curvature nicely.

So now I have to get stuck in to making all the rest of the triangles and covering them with plastic.

Ultimately there will be a detailed step by step article on the Geodesic Dome Page of this Blog

More soon

Dedicated to living a simple, independent, self reliant life where money is not the main factor. My dream is to engineer a life that requires very little from the outside world. I would like to provide my own shelter, collect my own water, grow, catch, hunt, forage my own food, create my own energy and deal with my own waste. This dream all starts in a tiny allotment in Cornwall where I will be experimenting in growing food, generating energy and dealing with waste.

  1. Did you work off a set of plans, or just wing it? I don’t see any prefab “hubs” between the boards – so I assume the triangles just attached to one another directly?

    I am considering a small dome (about the size of yours, maybe a little bigger) as a “Shed” (aka “man cave” on some property we own.


    • I worked off a set of plans. There are no complicated hubs to build just triangles and they are attached to each other to form the dome. It is a very simple design.
