How to Use the Dome Calculator

1. Select Hub Size:
Select "No Hubs" to get the true "chord" length for each strut, which is the full distance for the strut between each geodesic dome vertex.
For most dome construction methods, you will use the "No Hubs" selection.
With our Zip Tie Domes Hub Design, the geodesic dome vertex is located in the middle of our "Center Ring".
When using our Hubs, the width of our Center Ring must be added to the strut length to give the true geodesic dome dimensions.
Select Standard 4" Hubs for calculating domes with our 4" Standard Hubs or Dual Covering Hubs, which have a 2.375" Center Ring. These hubs are used with 1" PVC pipe for struts.
Select Super 6" Hubs for calculating domes with our new 6" Super Hubs, which have a 3.5" Center Ring. These hubs are used with 1.5" PVC pipe for struts.
Select Mega 8" Hubs for calculating domes with our proposed 8" Mega Hubs, which will have a 4.5" Center Ring. These hubs will be used with 2" PVC pipe for struts.

2. Feet or Meters
Click the button for "Meters" if you are using metric measurements.

3. Data Entry:
Enter a number with or without a decimal fraction in any of the number fields on the left. (For example, enter "5" or "3.3333")
Click the Calculate Button. All of the other numbers will be automatically calculated.
The Blue Struts are always the longest struts. If you know your longest strut length, enter your data for the longest strut length in the Blue Strut field.
To build a strong dome, the longest strut should not be more than 6' long.

Cost Calculation and Material Utilization Chart
The default "Length of Pipe" for cutting your struts has been set to 10'. You can change this to 20' or whatever length of pipe you have to cut for your struts.
You can also update the "Cost Per Pipe" amount, and click the Calculate field, and the "Total Cost of Materials" amount will be calculated at the bottom of this section.
If you are cutting 4' struts, consider using 20' lengths of pipe, as there will be less waste as compared to cutting 4' lengths from 10' pipe.

Alba gu bráth - Scotland Until Judgment

The Rigs O' Barley

It was upon a Lammas night,
When corn rigs are bonie,
Beneath the moon's unclouded light,
I held awa to Annie;
The time flew by, wi' tentless heed,
Till, 'tween the late and early,
Wi' sma' persuasion she agreed
To see me thro' the barley.

Corn rigs, an' barley rigs,
An' corn rigs are bonie:
I'll ne'er forget that happy night,
Amang the rigs wi' Annie.

The sky was blue, the wind was still,
The moon was shining clearly;
I set her down, wi' right good will,
Amang the rigs o' barley:
I ken't her heart was a' my ain;
I lov'd her most sincerely;

I kiss'd her owre and owre again,
Amang the rigs o' barley.
Corn rigs, an' barley rigs, &c.

I lock'd her in my fond embrace;
Her heart was beating rarely:
My blessings on that happy place,
Amang the rigs o' barley!
But by the moon and stars so bright,
That shone that hour so clearly!
She aye shall bless that happy night
Amang the rigs o' barley.
Corn rigs, an' barley rigs, &c.

I hae been blythe wi' comrades dear;
I hae been merry drinking;
I hae been joyfu' gath'rin gear;
I hae been happy thinking:
But a' the pleasures e'er I saw,
Tho' three times doubl'd fairly,
That happy night was worth them a',
Amang the rigs o' barley.
Corn rigs, an' barley rigs, &c.
