For y'all Monday morning viewing pleasure,
Was able to sneak away for a 1/2 day shop time anyway this weekend and Eon met me there so we decided to give the pulling post and pedestal mount V2.0 a try.
This car is very stubborn about giving up some metal movement..., really emphasizes the lick Eon put on that RF corner at the CC race.
I haven't done the geometry to figure out the multiple but I have a 2.5 ton (5000lbs.) jack pushing a 2" thick wall box tube arm with the hinge point at virtually -0- and the pushing pivot about 8-9 inches up from there.
We have never maxed the jack out yet so I'm definitely pulling less than 5000 lbs... ;D
Here's the pedestal, aint really pretty but it's strong as hell.
Would have done it differently second go around from scratch but it's just revised and strengthened....originally, the plate bolted to the ground buckled,
It has two 180* eyes that slide in on the bolts to the crossmember and are tightened between the crossmember and the chassis itself.
We picked this spot because it is very strong there and directly in line with the strut tower vertically,
It was the hit on the RF wheel and ultimately the strut housing that really did the damage. The RF Leda strut tube was kinked about 20* and this force was transmitted to the strut tower and a-arm.
I modded an engine pulling bracket for the strut tower pulling mount,

Here you can see the pulling post. The design is actually notched at the top for the chain links to slide into but I didn't slot it deep enough so we just wrap the chain, use the c-clamp for safety as well as the blanket that you see on the floor, draped over the chain to slow inertia in case it were to let go past the c-clamp,

We used this other tool I made to pull the fender mounting flange while the pulling post is loaded. It's attached to a 5lb. slide hammer and helps to define the area you want to move a little better,
again, for a unit body car, this thing does not give back a 1/16th" without a lot of force, I have V2.0 of a tool to replace this one (pics later ;D) to finish the job off so the fender fits the flange 100%,

Finally, around to my own project......Eon gets all the stuff mounted and in line himself, I just wander over when the pulling starts so I had time to do a couple of things to my own car.
Got the little yellow wedge done in the first pic, small diamond is the factory jack location marker but I sprayed it yellow to show up better at the track for quick jacking , second one finally shows how the scheme lays out with a fender attached,

Not much of the white stripe carries onto the fender, but..., all three cars are the same, the dude that owns the property where my shop is cut the grass when the car was outside and aimed the chute right at my car
so the fender has a lot of dried grass on it...

And finally, got the left side rocker all squared away and ready for the chip guard spray step, still working on that left 1/4 panel though...![::)](//storage.proboards.com/forum/images/smiley/eyesroll.png)

Carver - I have a few pics in hyperspace right now that I'll post later, a couple of screen shots of the tube bender software I told you about and at least one of a 17 inch single TIG pass I made on this new tool with one side being 3/8 thick flat bar.
No gloves....![:o](//storage.proboards.com/forum/images/smiley/shocked.png)
Machine never even duty-cycled out.
Not bad for a 165 amp machine....![;)](//storage.proboards.com/forum/images/smiley/wink.png)
And hey, if I make a run this week with Kolachis or a lunch visit, I might even bring my new 3M Speedglass helmet and let you hold it.... ;D
