Frame prep
 

Just a question.....what is the best way to approach the frame of a classic vehicle once the body is off. The best way to detail it. Where does a guy start.

Here's what I did for my chevelle:

Take absolutely every nut and bolt off it.
Check for straightness.
Grind and MIG weld over all the factory welds (which look like chicken poop)
Box it for stiffness if it's not already, gusset anything that looks weak.
Check for straightness (all that welding might cause warpage)
Mock up engine/trans, narrow crossmember, make crossmember brackets.
Sandblast, prime, and paint.

Too bad i ran out of money, and that's as far as I got :rolleyes:

How do I go about boxing the frame????

Well, first of all, what kind of car is it? Some cars have boxed frames stock.

Chevelles are what I know, so that's what I'll talk about :) Chevelles have the side rails made out of 1/8" thick steel bent in a big "C" shape. The open end allows a lot of flexibility, which you don't want. By welding a plate onto the open side to close it, it makes it much more rigid and better for cornering.

I just traced a pattern onto cardboard, and plasma-cut out a some new 1/8" steel pieces to fit. Any welding shop could cut the pieces for you, if you don't have the equipment.

I'll look for some of my pictures I took of what I did. :)

I've got a good picture and a short description of the crossmember mount fab-work here:

Sorry about the links in that topic. They don't work now, after TC upgraded the forum.

I just got all the brake lines and fuel lines, & rear end off of mine. Will use this nylon bristle thingy on a drill to basically clean the frame. I have alot of surface rust. Oh yeah, I used some oven cleaner to get the grease and grime off everything that had it. Then this nylon thingy to basically clean. Plan to either POR15 it or try this Zerorust. After that, I may get some stainless nuts and bolts to put back in.
