I built a wrap bar and on the first time out I busted it just by doing a burn out (just did a SOA and 350 conversion). I started the burn out initially in the dirt, and then when the tires caught on the asphault, the bar snapped. I thought the design was pretty solid, but was proven WAY wrong.
I am trying to get some ideas of how to salvage the main part of the bar and only replace the slip part that mounts to the frame. Clearly the solid stock didnt work they way I had it set up.
The design uses a slip shaft, and the slip shaft sheeered where I had it go into a sleeve. I had welded the sleve to the slip shaft there as well.
The main bar that attaches to the axle was 3/16" DOM with a 1" inner ID. Into that slides the 1" piece of solid round stock for the slip shaft. That solid round stock was slid into another sleve on the opposite end and welded together. The sleve was then sleeved again with another inner sleeve that was threaded on the other end of the stock so I could screw in a heim. Basically- the only reason for the sleeve is so I can thread the heim into it. Initially I wasnt going to use a heim, but changed my mind on that later- so some of the pics dont show the heim.
The shaft broke right where it enteres the sleeve and was welded. I didnt aneal (sp?) the metal, so I hoped the metal wasnt going to be weakened. Guess I was wrong.
pics:
The basic pieces. The shaft attached to the plate is bolted in the wrong bolt position in the picture, and I later changed out the mount on the slip shaft to use a heim instead, but you get the idea.
Mount for the front of the bar. I welded the hanger to my t-case mount..
One more showing how it broke. You can see it failed where the solid stock goes into the sleve, at the weld.
I would like to keep the design, but am looking for suggestions on materials to use instead. My heim is a 3/4" heim, so may be overkill. Do you think I could run 1" outter ID DOM and thread in a 5/8 in heim and have it hold up?
thanks!
