Knuckles are cast steel right? So you can use a normal wire/rod and just preheat and allow slow cooling? Never really understood welding cast stuff? I should probably beef up my knuckles and for $40 why not? Need to get in there to do my kingpins anyway
Yes they are weldable with regular steel filler. I pre heated, tacked the piece on then heated the plates and beat them to conform to the knuckle, then burned it all in. Lastly I warmed the whole knuckle back up so it was even and then allowed it to sit and cool all the way down on its own.
I'm in the middle of finishing these. I'll post pics when I'm done.
