NOTE: If you enter a measure in feet, your results are in feet or, in the case of floor area, square feet. Same goes for meters. When entering in feet, decimals are fractions of a foot or square foot for example: 2. The formula is: tip to hole center X 2 X number of struts.

Keeping the sticks light in weight will help when going to larger diameters. For stick ideas and advice on where to buy them go here. Minimises clashing during the build, keeps the weight down and is a good size proportionately in relation to the hubs and ball connectors. You can use wider sticks but it does lead to more stress during the build process; the dome is heavier and the sticks are more likely to clash. We recommend tapering wider sticks although a diameter of up to about 50mm will sit in the hub without clashing, once in position. The stick lengths are 88mm shorter than the values here to account for the space the hubs and ball connectors take up. Note that the pentagons are shown complete to aid understanding of the component parts. As a flat pattern there would be a triangular gap between the edges of two of the triangles. Once joined together the pentagons would have their 3-dimensional form. Mini kit DIY kit. Insert values in any green box and all other boxes will update automatically.

Hi Neil With struts, hubs a 6v is very labour intensive.

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. When using our Hubs, the width of our Center Ring must be added to the strut length to give the true geodesic dome dimensions. 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. These hubs are used with 1.

It will calculate gore section dimensions, height and width along with coordinate points to help you draw the outline of the gore. Simply enter your dome diameter and the number of gores. Download in. RAR format. XLS format. Your circumference will be Because you need more than 25 gores, your actual required number is

For timber domes, angles should be to the nearest tenth of a degree. Click here for assembly diagram Struts are vertex to vertex To connect together with bolts, you need to make them longer to drill holes in them. Many types of connectors are available for steel and timber geodesic dome.

No Problem Nathan, I'll post a thread in the forum to discuss this firther Dome Weight Chart. Thanks Joe. Read more in our guide. Thankyou for a great and needed site, Im considering a large geenhouse and after reading a few of the posts feel anyone wanting a large poly covered dome needs a 6v or 9v calculator so the openings dont flap in the wind. Hi, I am looking into building a ' dia. Tunnel Dome 18 Ext. Insert values in any green box and all other boxes will update automatically.

The dihedral angles for the "X" panels 30 pent triangles are 11 degrees for the "A" sides and 7 degrees for the "B" side, vertex angles are Dome Radius r.

Hi trapper, Planning everything down to the last detail before you start has to be top of the list. In the case of the 2v icosa hemisphere, the floor is a regular decagon 10 sides. Hi again, My earlier comments about dome floor area pertain to the 2v calculation tool. These hubs will be used with 2" PVC pipe for struts. The formula should be 2. It may be better to use the 3v design which has more struts and shorter strut lengths 6ft vs 10ft for the 2v will be stronger and create smaller triangles. I posted the above as requested, but I wonder that something more sophisticated is required for such a high frequency sphere, because just simple point-connected struts will invert and errors in strut lengths will aggregate. Feet and Inches:. Thanks for your time. I would really appreciate a similar color coded layout of all the struts if anyone has one. I think if you were to bend at 8 degrees the difference would tighten up with the bolts. Tunnel Dome 13 Ext. I would like to build a 3 frequency 12 ft.
