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

A Man's A Man For A' That

"Is there for honest Poverty
That hings his head, an' a' that;
The coward slave-we pass him by,
We dare be poor for a' that!
For a' that, an' a' that.
Our toils obscure an' a' that,
The rank is but the guinea's stamp,
The Man's the gowd for a' that.

What though on hamely fare we dine,
Wear hoddin grey, an' a that;
Gie fools their silks, and knaves their wine;
A Man's a Man for a' that:
For a' that, and a' that,
Their tinsel show, an' a' that;
The honest man, tho' e'er sae poor,
Is king o' men for a' that.

Ye see yon birkie, ca'd a lord,
Wha struts, an' stares, an' a' that;
Tho' hundreds worship at his word,
He's but a coof for a' that:
For a' that, an' a' that,
His ribband, star, an' a' that:
The man o' independent mind
He looks an' laughs at a' that.

A prince can mak a belted knight,
A marquis, duke, an' a' that;
But an honest man's abon his might,
Gude faith, he maunna fa' that!
For a' that, an' a' that,
Their dignities an' a' that;
The pith o' sense, an' pride o' worth,
Are higher rank than a' that.

Then let us pray that come it may,
(As come it will for a' that,)
That Sense and Worth, o'er a' the earth,
Shall bear the gree, an' a' that.
For a' that, an' a' that,
It's coming yet for a' that,
That Man to Man, the world o'er,
Shall brothers be for a' that.

Robert Burns - 1795
