We fit hi mis uniballs to the diff end, and run a bit of 6mm flat under the pipe section scolloped to the eyes at each end and welded to them as well.

WE have found the diff end eyes can stretch oval when abused also, as well as bending the arm.

What is high carbob sounds like a dietry intake :? but seriously what is the actual classification/specification that you used. Interested for a couple of other projects.

the bush eyes i get made up out of the same material turned up to suit STD bushes and the hollow bar is called ASSAB750V hollow bar its high tensile steel i use 32mm od 16mm id for steering gear and arms up to about 800mm in length there heavy but tough as nails and i tig weld the ends on with LW1 filler wire as a root run then cap weld with the mig with the same filler wire which is virtualy standard run of mill mig wire

Chris have you had any trouble with the bushes distorting. Do you sleeve them with say ally or brass or ream them afterwards or do they not distort enough to bother seeing as you are using rubber bushes.

Na no distorsion prob you are talkin about the bush eyes once welded on right i havent had any dramas as i shape the ends of the arm to meet up nicely on the eye tube notchers are great for this tho ya need good hole saws and good lube :D :D :D

Yeah I was talking about the bush eye ends. Didn't think there would be enough to worry about with rubber bushes. Just remember seeing some work on race car stuff where they did remachine after but their bushing system would be something solid or near solid where they need perfect alignment and the slightest distortion would not be tolerable.

You could always order some arms from superior engineering. I put a set in my cruzer after i bent mine two years ago. :D

Superior engineering have heavier duty ones with a strongback on them, or they have done custom super heavy duty ones as well.
