Yes. I have about 100000th of the budget that the Eden Project had.

I am hoping to build mine for about £500 compared to the £50000000 to build theirs

Things are moving on now and it all seems a little less daunting.

I was expecting it to take about 10 minutes to make a triangle but I can do them a lot quicker than that and that was the first ones I have built and I haven't really got a system going yet.

It took me about 30 minutes to build 6 triangles and then assemble them into a hexagon panel.

This is fantastic as I was thinking it was going to take weeks to build a dome but if there is the two of us and we have a system I reckon we could do a dome from start to finish in a few days and a day installing.

Anyway. I am pleased with the potential speed at which I could build a dome if I had all the materials at hand. I have run out of screws now so have to knock it on the head but I am keeping a note of everything I need so when I am building future domes I will know I have all the materials and supplies on hand before we start.

I am getting excited now

Thanks Guys
I didn't get to do much to the dome over the weekend as I had to work but I bought some wood preserver that was on special and a load more wood for he triangles. I just need to get some more screws and I will press on with making the triangles.
I have also priced up the cover and it is only going to cost about £90 so that is not too bad.

Does anyone know how dangerous the sawdust from tanalised wood is?

I am going to end up with several sacks of sawdust per dome built and I need to know what I can do with it.

Came across this by Googling tanalised wood:

https://groups.google.com/forum/#!topic/uk.rec.gardening/sexa7FIsOs4

Do you know what it was treated with?

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.



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.



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.



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

This project is still ongoing. We have nearly built all of the triangles and the next stage will be to cover the panels with plastic.

Work has kind of taken over a little but we will get there

Nearly finished all the triangles just a few more to make and that is the bulk of the woodwork done.



I ordered the plastic cover today which should be here tomorrow.

Then I need too get busy covering the triangles in plastic ready to actually build the dome next weekend if the weather is good.

In the last two hours I turned these



into these.



38 triangles. So that is all the triangles including the custom ones that go around the door done.

The plastic didn't arrive today but that is OK. As long as it is here by the weekend I will be happy

All the triangles have been sanded to accept the plastic and I have started covering the panels in plastic. I am going to knock it on the head because it is difficult on my own so I will need Jules to give me a hand with covering the panels.



I am now off down to the allotment to start prepping the base so we can start erecting the dome next weekend.
