custom steering Knuckles and getting max lock

[sundee]

Ahh That statement is false. just because its welded doesnt meant its going to hang together at all.. and if they have put an effort in like that it doesnt show skill or workman ship, it shows a hack.
The weld needs to penitrate the metal properly to create the right fusion.
its not just a matter of slapping on some weld, because the weld WILL just break..

Intense: Run XT130 LCA's and you'll have no problems with PS arms.

I'd imagine they would have done it properly before thinking about selling to mass amount of buyers over yahoo auction. Their ugly welds, but seeing it in person it looks solid enough, how can I tell for sure though but that's the way it seems.

3up arms are welded once... the garage clear ones, have been welded a few times.. y?
because the 1st weld wasnt satisfactory.

the 3up arm have been cleaned up but u can see the area that has been cleaned up.. and its isolated to the area of the join itself....

no point arguing, i just know IMO i would never put something like that im my car..
but each to their own.

....and you shouldn't really grind welds because that weakens the weld. I have a boilermaker friend that pointed that out to me.
But I'm with Ken about them being mass produced and and safe as any other.

Cheers Boost.

if you wanna know if its a safe weld xray it or cut it in half

[Touge Boy]

I wasnt going to get involed in the whole welding debate... but since Im here.

Straight away.... there's a chance it can crack.... simply cause it's cast metal which has been heat cycled.. No if's or buts. Heat turns cast brittle. This is fact.

BUT, if the cast has been pre-heated properly before, and proper weld preps done, the chance is a lot less likely. So unlikely that if you were to hit something, the cast itself would bend/break before the weld would.

The garage clear arms would be fine.... if they have been prepped properly. They dont look like they have been welded twice either... more like 2 or 3 massive high heat/high feed fillets

Ive made my own knuckles.... S13 to be precise, and they had 18 x 11's on them, and pushed to an inch of their life. Gutter hits and all. No cracking at all. only bent one. And it's cracked.... because I was lazy and stupid and I heated it with an oxy and bent it back out again.

90% of most "extra-lock" knuckles are cut and shut. Only a select few arent.... GP SPorts comes to mind. But then again, you pay the premium for them.

As fantapants said... X-Raying is really the only PROPER way of knowing, magnetic particle testing would work too, but I think it's a bit overkill in this case.


In short.... I would happily use cut and shut knuckles..... if I had done them myself. But if the proper prep and work have been carried out, they'll be fine. If you still dont want to use them... then dont. End debate.

Touge Boy.. they're FORGED.. not CAST.. But same rules apply... Good preheat and 100% weld penitration and you laughing..

X ray is the best... Mag particle only shows defaults at the surface of the weld and can miss quite abit..

Your got your knuckles in yet Robo.??
Any feed back.

[Delazy]

and more ppl had trouble with them than they did with cut and shuts...

basically the reason they are no longer availabe is that too many ppl were snapping them...

pickering killed his with a minor tap, while josh coote also bent his from quite a minor love tap...

meanwhile ppl with cut and shuts go bouncing off rippled strips into walls and they survive to skid another day....

[Touge Boy]

I assume you're talking about AE86 arms? Cause I know a lot of nissan stuff is Die-Cast. But either way, as you said... same rules apply. And yeah, X-Ray is the best, mag particle was just another example, but all were beside the point...

If they've been well though out, prepared properly and welded well then there shouldnt be an issue.

And it's quite strange isnt it... you'd "THINK" that a properly made aftermarket knuckle would take some punishment, given it's use. Weird.
