3V 4/9 (3/8) Kruschke Assembly Diagram

The same pattern is repeated 5 times. The greyed out area represents the core triangle.

Bend angles for pipe or EMT geodesic domes can be rounded to the nearest degree

Bend angles for timber domes should be rounded to the nearest tenth of a degree (or 1 decimal point)

 

 Note: there was an error in the strut count which is now fixed.

For a 3V 4/9 (3/8) Krushke flat base geodesic dome you need

30 X “A” (ends bent or cut at 9.49°)

30 X “B” (ends bent or cut at 11.02°)

50 X “C” (ends bent or cut at 12.16°)

10 X “D” (ends bent or cut at 12.74°)
