You're going to need a bunch of 3/32 brass rod or tubing to put this together with. Goes together like tinker toys -- a rangy, cranky set of tinkertoys...

all of the brass is 3/32 diam.
The long rods used to connect the front and rear spines are about 3.85 inch
The short rods connecting the dome grid are 1.666 inch
The rods running through the top level of the spine are 2.56 inch
The rods running through the lower level of the spine are 3.79 inch
