Subdivisions of Garden Dome 2

Using standard 8 ft. lumber, the dome diameter will be approximately 27 ft (longest strut is 8 ft, one strut per board).
Height will be 13' - 6" and ground level area will be 535 sq. ft.
If two struts are cut from the board, diameter becomes 15 ft.
If 10 ft. boards are used and two struts are cut from the board, diameter becomes 18 ft.
These sizes are suggested for less waste of your board length and "more dome for your money."

Three basic additions of struts may be added to the dome.
Designated X1, X2 and X3 these new dome frames offer added
structure and strength, and added frame work for attaching roofing material.

The Garden Dome 2 - X1A
With X1 struts in the pentagons and X3 struts with 10 connector hubs added in the equilateral triangles between the pentagons. If long struts (brown) were 8 ft, dome diameter would be approx. 27 ft., so this would be an ideal maximum size for the 2 x 4 Garden Dome 2 (but could be larger especially if 2 x 6 lumber is used). Also a 4 x 8 sheet will cover two of the larger triangles; right triangles that are easy to cut with a hand held or table saw.
