member was asking for pics of these, I hope you see them. I don't have your contact info...

All 1/4" plate and it takes some finishing. They are formed.... sort of. It takes some heat and weld to put them in place.
 
Will all that welding distort the knuckle?
 
Haven't put them on the site.

$40 per axle. I'll try to get some pics of an unwelded kit so you guys can see how much forming is needed.
 
Not if you take your time. Work on both sides at the same time and jump back and forth. Drink a beer and so on.



Regular MIG wire is ok? or certain type?

And is that a beer for every time you jump back and forth per side? just want to make sure I'm getting ir right :wink1: :D

Regular mig wire works fine.

And if we're getting technical with the timing, it goes.. Weld, switch sides, weld, shot, beer chaser, tell 3 lies and repeat!:D

So, you're saying this will take more than one weekend to finish:confused:
 
any chance this could include inner C braces too?


Are you guys brakin' inner c's too??:wink1:

Hadn't really thought about building bracing for those. Our knuckle tabs reinforce the top portion to some degree but something could be designed a little more specific to the job.

the knuckles are made of cast iron, right? or are they steel?

i know you can weld steel to iron with mig wire, but isn't there usually an annealing process involved?

otherwise, wouldn't you want to use a special wire, so that the iron outside of the weldzone doesn't crack?

correct me if i'm wrong, but i think bronze silicon is the correct wire.

We've never done any special prep or wire selection. The knuckles weld up pretty good. If I were to do anything, perhaps post heat and slow cool for normalization around the HAZ and feathering into the entire knuckle.

Knuckles on my blazer had no pre or post heat or cooling control in any way shape or form. Been beat on a few times and so far so good.

If you for some reason, think you may need to machine the weld in the future, then you may want to pre heat and post heat and most definitely control the cool down. If not, you'll have a hard time doing any machining later short of grinding. It'll be very hard.


EDIT: Technically speaking, there probably was some amount of preheat in our process now that I think about it. With the press brake we can do some rough forming on the pieces. The rest has to be done on the knuckle with some flame and a hammer. So, the knuckle is getting heated to some degree.
 
The knuckles are cast steel (not cast iron) IIRC, so they should be weldable. In fact they are welded on at the factory, unlike the pumpkin which is iron and is plug welded.

yeah, i wasn't quite sure what the material was that the knuckles are made from. cast steel definitely makes a lot more sense. i doubt that cast iron could withstand the stresses that the steering knuckles undergo. i will go ahead and put my foot in my mouth now.:doah:
