Title: Sling
Post by: JoeBlystfk on January 15, 2012, 01:31:14 PM
Pardon my ignorance but in reading the rule I see reference to a "sling" in regards to the trailing arms that locate the torque tube type driveline. What is a "sling" ? Would this be some sort of lanyard or cable to keep the trailing arm from falling down if the rod end failed ?

  Yes...on our bottom 4 link there is a bracket [ a 3/4'' long tube slipped over 4 link bar with another bracket fabricated on top with hole for small cable and braced down to tube for strength] cable runs through hole and around bolt located
in one of the unused 4 link bracket holes and looped back to other end of cable and bolted with cable bolt.]  This is a fabricated one piece design but basic design could be fabricated by welding. Cable needs to be attached to frame.

  I miss Little Abner, one race crew I know were called ''the '' Niki Hoki Boys'' :-D

Like JL222, I use a a small(1/8) cable. I welded a small tab with a hole in it to the bottom 4 link bar. I attached one end of the cable to the frame, ran it through the hole in the tab, then attached the other end to the frame. The 4 link is now in a 'sling' and if the heim were to break, the 4 link could not hit and dig into the ground.

Are you sure 1/8" is strong enough? My rulebook, section 3.S, page 37 calls out a minimum of 1/4" in all places in paragraph 2.

Look at the tail gate cables on different trucks most of them are 1/4" cable, make sure you don't figure in the plastic cover as part of the 1/4".  The ends are silver braised into the cable for a strong connection, and they are the perfect lenght for this application.

 Note what truck and year, then get them from a parts store, I don't advocate stealing them from the truck.  The mayor of East Wendover makes a killing on these every year along with metal tire valve caps, and inertial shut of switches at his parts store. 

Don't use the cables from a Nissan truck they could be damaged from landing airliners, snowboarding of mountain tops, and pulling C vans up out of the canyon.  Oh and pushing dune buggies over dunes from a dead stop.   :-D

Just go to your freindly neighborhood RV parts store and order pre-made 1/4" cables in assorted lenghts. They are tow bar and bracket accessoies. They are even nylon coated.
