The Blue Struts are always the longest struts. All of the other numbers will be automatically calculated. (For example, enter "5" or "3.3333")Ĭlick the Calculate Button. These hubs will be used with 2" PVC pipe for struts.Ĭlick the button for "Meters" if you are using metric measurements.Įnter a number with or without a decimal fraction in any of the number fields on the left. Select Mega 8" Hubs for calculating domes with our proposed 8" Mega Hubs, which will have a 4.5" Center Ring.
These hubs are used with 1.5" 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" PVC pipe for struts. Select Standard 4" Hubs for calculating domes with our 4" Standard Hubs or Dual Covering Hubs, which have a 2.375" 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. With our Zip Tie Domes Hub Design, the geodesic dome vertex is located in the middle of our "Center Ring". 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.įor most dome construction methods, you will use the "No Hubs" selection. 7 Trumpets Prepper - A Visit to Zip Tie Domes.7 Trumpets Prepper - Zip Tie Dome Build.
