Hi Gijoecam,
I am trying to follow your words and unfortunately I can create at a few possible combinations from the wording.
We are OK with a hand mocked up sketch to get the point across. Go for it.
In my opinion, a better design for this setup would use a pair of arms extending from the ball below the coupler parallel to the trailer tongue that the chains would connect to.
Need a few more words to help "a pair of arms extending from the ball below the coupler parallel to the trailer tongue"
The tow ball in this case is made of a ball sphere attached to a long tapered shank. I have "estimated" the shank may be 8" long below the ball sphere. Again a hand sketch here really helps.
How far down from the ball sphere are you attaching? 1/2" or 6"?
Are the long part of arms attached at a 90 degree angle to the ball shank center-line when viewed from the side of the A frame?
Approx how long are the arms?
Parallel to the tongue. Again lost which direction. Parallel to the ground? Parallel to the 50 deg inclusive angle of the A frame ( the V of the frame) or both at the same time? Or parallel to the ball shank which is parallel to the front vertical surface of the tongue?
Tightening these chains would try to pull those arms down and into compression against the ball-end, the same as the current setup pulls the trailer tongue.
Then, since the resultant force will be down on those arms, simply hool the ends of those arms over top of the frame rails. That would allow the resultant force applied to the trailer tongue to be only downward instead of forward and down, and since the whole assembly would still turn with the trailer, the sway-control inherint in the Andersen design would still be retained with little or no movement of the ball relative to the coupler.
We need to know more on how bars are attached to the ball.
Interested in your idea, just cannot visualize it to line up with the wording of the 2nd paragraph.
Thanks
John
