[amsat-bb] Screw threads on Arrow?

[David Rush]

I'm fairly certain that mine, purchased more than 10 years ago, is using 
actual arrow shafts, not something based on arrow shafts.

And I'm 95% certain that it's 8-32 threaded rod that connects them. It 
looks like 8-32, and I pulled a random "this looks like an 8-32 nut" out 
of my bin of random machine screws and nuts, and it fit just fine.
