Taking frame apart

Blub

 

How do you plan on reassembling the frame?

 

Have you priced a new frame? It may be worth replacing the frame vs rebuilding the frame.

 

Are the rivets rusted badly... what makes you think bolts and nuts are going to be stronger than heat treated welded rivets?

 

Best of luck! I do wish this was in the 3rd gen section though.

 

I hope this is not a daily driver.

 

Ok.. I would have to Google that process. I have not a clue what that means.
You asked for thoughts and concerns. Those would be mine.

 

A zinc dip is something people do to frames during restoration. That's a fine thing. A lot of work before and after (you have to chase every single thread for example).

Doing that I would just have the frame stripped in a bath and dipped as is, no reason to go to the trouble of disassembling it since it's all going to be coated anyway.

I believe that there are other frame dipping processes that do not include disassembling the frame. If I were rebuilding the frame, I would look in that direction.

 

Ok.... I bet it's not a daily driver or used as a work truck. As a school project car... I could see this.
I guess it just depends on his needs for the truck after complete. I would worry about stretching and loosening of said nuts and bolts. Plus dislike metals tend to rust faster when they are next to each other.

 

Just don't weld anything to the frame after that. #yergonnadie

 

I would spend the $$$.

 

I'm gonna go out on a limb and say that most of the guys around here have not tried to rebuild their frame

 

I tried to rebuild a coilover and had spare hardware when I was done...never mind a frame.

Thank god that wasn't my truck.

 

That is classic!
I'm prolly gonna use that.

 

That's a good point.

 

The point of the zinc coating is to be a sacrificial anode in contact with the steel, e.g. "cathodic" protection, so would work even if the coating has gaps or voids.

Anyway, not sure why cathodic electrophoretic dip coating (e.g. CDP) is OK in Europe but plain galvanizing would not, since the first step of CDP is a zinc phosphate wash, which is essentially a thin layer of what a fully galvanized frame undergoes for the CDP to adhere.

That is a very legitimate concern with the thin walls in modern frames. Old FJ40s and Land Rovers used thick steel, much thicker than our current Tacomas and Hiluxes.

 

True dat. And since your old Land Cruiser will last 1,000 years (or so I'm led to believe) after galvanizing that might be a concern one day when your ungrateful kid inherits your junk and turns that frame-off garage queen beauty into a rock crawler.
