1982 Cordoba Stock Car.

I was wondering the same thing myself. He tried calling me a couple of times after he was here, but I missed the calls. :hmmm:
 
You must have been out Friday night, I called you a couple times too to no answer. :D

It kinda sucks because I'm installing that roll cage the first week of August no matter what as I will be on summer holidays.
 
Got the K-frame almost finished, drilled the holes out to the proper size, now just to touch up some of the welding and paint and it's done.

Unpacked my jigsaw puzzle. :D

Made up some spacers for my steering knuckle, 2+ Degrees of Negative camber these are apparently good for.

Ok last night I got lots done with the help of my father-in-law and a good friend of mine.


Found out by chance that this little car without bumpers is exactly 16' long. :D

Leveling the car was a piece of cake, the floor is nice and level and the car is very straight.


Cleaned the floor and then set about transferring the cage diameters to the floor using the transmission crossmember as a starting point, getting them square and then cutting the rocker panel to make room for the main hoop and the window posts. The shop's car just had the roll cage mounted to 1/4" steel plates welded to the floor pan. This cage will be a integrated part of the car's frame structure as well as plated top and bottom with 1/4" plate.

This rear portion that is removed will allow us to properly box together the frame rail to the cage and to the rocker.

The cage is with in less then 3/16" of square overall. I was quite surprised that this unibody car is as square as it is. Everything fit nice.

Now with it square and everything tacked in place we started doing our top welds before painting the roof and the top of the cage and then lifting it back up and then securing the bottom.

So everything is where is should be and all that is left is the cutting and welding in of the plates and floor patches. I forgot to paint it before it went back up. :doh: :D

All the preliminary welding is finished for now. Keep in mind there are plates to go on the bottom of the rockers.

Looking good so far! :dance:
 
Some more progress.

Taking the rules to the letter which state "stock bumpers, mounted with stock mounts in stock location." Doesn't state I can't modify said bumper mounts. :D

They all came apart to my surprise.

Drilled holes, drained the oil and cut them down with the sawzall.

2012-08-03214846.jpg



Slid them back into the outer bumper shock housing and welded it together, much stronger and safer.

2012-08-03214858.jpg



The header panel will not be going back on as I have special plans for that but I wanted the bumpers to sit closer to the body and this was the easiest way.

2012-08-04152935.jpg



Rules allow this cross bar so I'm installing them and welding the bumper shock plates to the tubes and then welding the plates to the end of the frame rail with some small beads.

Even though the rules forbid any pipe or reinforcement ahead of the front firewall or behind the rear firewall I am making a small rear hoop with forward facing frame rail angle braces to protect my fuel cell, safety first! :dance: I have yet to cut it to fit against the tail panel and weld it in.

2012-08-05164056.jpg



Here are the plates for the cage.

The rear is two layers of 1/4" steel.

2012-08-05164221.jpg



The front is two layers of 3/16" steel. I have sheet metal floor patching to do before these go down.

2012-08-05164246.jpg



I also have some small 3/16" steel plates to go on the bottom of the rockers where the pipe comes through.


Gotta finish this yet also.

I got your book Stretch, wonderful read. I was quite proud of myself when they showed the exact same way of mounting a roll cage in a unibody car as what I have done with my car. I guess I have a better grasp of this then I had originally thought. :)

Most of the chassis tips and setup tricks in the book are illegal for my class the physic principals about the car's handling characteristics with different setups are still the same and are going to be very helpful.

Thank You! :)

I did that on my bumper mounts too. There is no question when the drill bit breaks through is there! :D That oil is really under some pressure isn't it! :D
 
No need for a drain pan when I did mine. My shirt and face pretty much soaked it all up! :D :D :D
 
ive actualy gotten smart on those presurized units and a slowly grind off a corner till it just starts spitting...flip it over and do the next one ....
