3pt prototype done Options

[Qucifer]

Ok guys, here is the prototype of the 3 point strut brace. I will build a jig off of this one. The production bars will be made of the same 1" diameter tubing with a .095 wall thickness. They will be fully welded, gusseted, and powder coated.

Qucifer,

Its great to see that you're doing something for the 6gc community and i gotta say the 3pt is very well done. However I got a few things i wanna say. If you look at the joints you welded, the joint are sitting higher than the bolting plate and there is a bend at approx 90 degree, this will have an effect while driving:

When you steering hard at a corner forces apply to both of sides and if the material you used isnt strong enough it will bends in the directions showed.



Most the forces will dissipate as heat through the 90 degree bends and overtime one or more bend will eventually crack. The bendings not only causing failure in the bar but also reduce the handling because of bendings instead of a straight stiff bar holding the suspension tighly.
All strut bar bend (stress & strain) when turning but how much do they bend depend on how well the bar is made, if you have the joints welded like the Jpspeed 3pt then the bending is keep to a minimal level. Also it helps if you use strong material like re-enforced steel or titanium (lol)..

Once again looking at this 3pt I think its every well made, if you can weld it flat with the bolting plate then it will be a great product.

edit: i found a pic on the site showing a Jspeed bar..you can see how the joints are welded to the bolting plate..the angle is abt 160 degree and the material used is i think is steel..
