Details for a 2v dome ball made from barbecue skewers


400 mm dia
Nominal radius = 200 mm
Actual radius = 201.6 mm


Actual rod lengths


A = 119.1 mm (60 required)
B = 105.2 mm (60 required)

5 way joiners 12 required (joiner clearance 2.20 mm)
6 way joiners 20 required (joiner clearance 2.77 mm)
 
see attached file for paper joiners
 


Actual rod lengths were calculated by

A = 201.6 x strut factor – (2 * 6 way joiner clearance)
B = 201.6 x strut factor – (6 way joiner clearance + 5 way joiner clearance)

Strut factor for A = 0.618
Strut factor for B = 0.546
