Re: New guy build-The Family Truckster

Soaked my WJ knuckles in apple cider vinegar for a few days to knock the rust off. Burned in the bearing spacers today. I started working on the double shear for the tie rod and drag link too. Not the most perfect welds, but I think they will hold.

Photobucket did me dirty. I'm on the search for a new hosting site. Any suggestions.

Re: New guy build-The Family Truckster

Did some more work on the lower control arm mounts today.

Re: New guy build-The Family Truckster

While the welds are beautiful on the lower mounts in that last post, I wonder if you wouldn't be better welding a fishmouth plate to the unibody, then welding to that?

I agree 100%. It's hard to see in the pictures, but I installed full length frame reinforcement plates from ruff stuff before I built the lower control arm mounts. So no need for another fish mouth plate. Plenty of beef.

FYI, apple cider vinegar is not needed.

Plain old white distilled works just fine. I've used it many times.

Ah, it's a thing of beauty.

I am looking to use those exact plates on my 90 and my son's 97. GREAT company!

Re: New guy build-The Family Truckster

More work on the WJ knuckles. Double shear for all the steering joints.

Re: New guy build-The Family Truckster

Beautiful.

Those knuckles are cast iron, right? How are you preheating/quenching?

Thanks. I did a lot of reading on various forums about welding to knuckles/center sections. They are a lot of opinions on what is the "correct" way to weld mild steel to these parts. Here is what I did.

Soaked the knuckles in apple cider vinegar to clean the rust off. This did a great job of getting them clean/rust free.

I used an old set of unit bearings to secure the spacer for welding. I pre-heated the knuckle with a MAPP gas torch to about 300 degrees then tacked them up with using my TIG welder at about 180 amps with 3/32" ER70S2 filler. I pulled the unit bearing off, then welded them up. I alternated the sides when welding to spread the heat around.

I welding them using 2 passes, and lots of post flow to prevent "hot cracking" from the two different materials cooling at different rates. It welded pretty smoothly. I let them cool in open air on my work bench. It took about 5 hours for them too cool completely. You can see a little bit of garbage from the knuckle in the surface of the welds in the picture. I'm happy with how they came out.

Re: New guy build-The Family Truckster

They look good. I'm curious how you managed temps- specifically how you determined the initial preheat temp- maybe an IR non-contact thermometer?
Also, more concerned with the dual-sheer bracket welding. The spacers shouldn't be terribly crucial welds, as they are held to the knuckle by the unit bearing throughbolts to the knuckle.

The dual-sheer are MUCH more crucial, as they have no reinforcement whatsoever other than themselves- they are the reinforcement.. and if they fail you're going to have an entirely too-interesting and exciting day.

By no means mean any criticism- I'm simply trying to add some tricks to my limited bag of tricks.
