Morning all, as you all know I have the Sani with MQ Patrol SFA and suspension conversion. Now I have ended up with a 7" lift and one of my projects is to install a sway bar.
I have a fairly wobbly ride, and the COG is now so much higher that cornering is an interesting experience.
As you probably also know, I build stuff on ZERO budget and from scrap I find laying around.
So here is the question.... Would a torsion bar be too stiff to use as a sway bar?
Another question would be if a torsion bar is designed to only take tension in one direction?
I have an idea to cut the left and right torsion bars and join in the centre.
Three main reasons would be:
1) Standard torsion bar is too long to be used as is. So to save and use the splines on each end, it would be best to cut the centre portion out to shorten.
2) As torsions are clearly marked for left and right, I have the feeling that they only take load in one direction. This would mean that I would need to use portion of each torsion bar to accomplish even load carry in both directions as required by a sway bar.
3) The centre joining point of the two torsions can fairly easily be made to be a disconnect. This would save me from figuring if the two ends can be welded or how to join them together.
The idea is to have a simple hex cut onto the end of each portion where they meet in the middle. The one side would be cut deeper than the other. A long 25-26mm socket can then be slipped over the two ends and by moving it, it will engage the two ends or disengage the one section from the other.
A simple sleeve would keep the two ends lined up no matter in which position the socket may find itself.
Should be easy enough to lock the socket in either the open or closed position.
The Jeeps have the Anti Rock system that I base the idea on, and I presume that the length of the arms can be used to compensate for a bar that is too stiff. But then you also don't want the flex to happen in the arms, but rather on the bar it self.
Simplest way I can think of to make a very tight sway bar with a easy disconnect as an added prize.
Other advantage is that using what I have, I am probably going to need about R100 worth of bits and pieces to do this job.
My one brother in law is a fitter and turner, boiler maker and welder, and tells me he can do the hex cutting on the joint easy.
If I can do this, the original sway bar that was on the front of the Sani can be employed in the rear, but the disconnect would be a pain.
Peter, I know you will be able to give me some advise on this one. So lets hear how good or stoopid I am in my thinking.
