thought about it but not what i was going for. just a slightly hopped up daily driver (maybe the next one!)
Nice work but I have to agree with Jamie. I dont think they're going anywhere either but I'd bet money it will eventually bend.
Since he's welded it on both sides of the rail, the bending moment is highly reduced, so it's pretty much so just in single shear, and a piece of steel that size will easily support that shear load. Even if it does fail, the rear end is still supported at 3 other locations so it will not be a catastrophic failure. From a design and FMECA analysis, I give it my engineering stamp of approval. Supporting it with some bracketing would get an even bigger stamp of approval though...
this may be good running in a straight line...not so good when turning and putting a side load on it....maybe bend frame rail. i would suggest the...spring mounts be center of frame rail...not to the side...
being the...rear shackles flex...it's only..."supported"... on two points. the rear shackle will allow side motion...(back and forth)...to cause a failure for sure... ...JMO...
Having seen the rear shackels bend on a center supported spring I doubt that the bolt will stand up to use very well. Wlding the bolt on both sides does NOT make it stronger or reduce the bending moment. It does provide stress risers at the spring side of the bolt and make the steel more brittle. All in all I would have boxed the support so it took advantage of the shear strength of the bolt rather than depending on the bolt to support the weight of the car in bending mode.
