I have set out to design and build a new style of radius arms for my old rig and thought I would share. Considering my last name, it's a different type of "Lars Bars"... ;D
Let's get into it. Here is a SolidWorks image of the arm I have designed.
The end cap and wedge on the arm are custom machined from a solid block. I want to keep the taper that runs along the inside profile, just like stock, to ensure the arm stays seated correctly on the bushing like it is supposed to.
Here is a closer view of the head assembly, when assembled, and exploded.
The exploded view shows how the main 2.00" x 5/16" DOM tubing will go all the way from the link at the frame to the end cap. This is a critical design feature, in my mind, and I did not want to terminate the tube just a few inches after meeting up to flared region like in some designs.
You can also see how the weld where the flare and tube meet with will be fish-mouthed to lower the stress. The upper and lower flared pieces are made from DOM. They will be joined by a triangular plate that will be plug welded to the main tube.
The arm will have a bend to it that is more than capable of avoiding 37" tires.
I have not yet nailed down the length I want, but it is currently designed to be 7 inches longer than stock, once the Johnny Joints are installed into the threaded bushing. The extended length is easy to change at this point.
Here are 2 blocks ready for machining into the ends:
A couple pics of the tubes:
That's all I have to share tonight. Looking forward to your questions, comments, and criticism. :-*
