[NSRCA-discussion] Ball bearing clevis'

[John Pavlick]

Great I'll pick some up this weekend. That will look nice than a bolt too since you won't see the head. I've already tapped the hard points for 6-32 so I'll use that. Do you guys epoxy the studs in or just rely on the threads in the hard point and a jam nut?

Actually what I also meant to ask was exactly which clevis' do you use. They're listed as 2-56, 4-40 and 6-32 but I'll end up with 6-32 "control horns" and 4-40 pushrods. Do you just use the 4-40 size so they fit the pushrod ends and drill / tap the other part for the 6-32 studs?

  I developed an understanding years ago that bolts are hardened and may eventually break.

  Ive use all thread rod from hardware store for el, rud, ail horns with no problem.

    I'm thinking about using ball-bearing clevis' on a new airplane. What is everyone using for 6-32 bolts through the surface and 4-40 pushrod threads? Also - what's the best thing to use on the control surfaces? 6-32 screws or threaded rod? I remember hearing that one or the other wasn't good because it was too brittle and it could braek.
