re-arching front springs

Is the key to re-arching front springs getting the spring eyes to center hole dimension of the first leaf between 4-7/8" and 5-1/8", and then arching subsequent leaves to nest evenly as you go?
 
I assume your talking vertical height of the spring when sitting on the floor in the same way it would be on the car. (I don't know the stock measurement)

This is the way to re-arch them, do the main leaf then make the others match.

The only thing to consider is that if your spring is now weaker then it was when new, you may need slightly more "arch" to get the car to sit at the same height when assembled.

I've only ever done this in the opposite direction to lower a car slightly.

Paul, That dimension is out of Les Andrew's handbook. The procedure(as described) seems fairly straight forward. Just was curious of experiences out there. Sometimes there is a 'trick' that doesn't make it into the manuals that is helpful.

Here is a spring that we reversed. You could do the same thing to the spring to add more stock arch. Just press the spring on the bottom side instead of the top side.

Oh, and the car is driving fine with the spring totally bent the other direction.

Maybe my question should have been when overhauling the front springs, is re-arching necessary? If they look okay, just grind the underside edge of each leaf and the top of each leaf(if the leaf on top dug in and left a ridge), clean up and re-assemble(?). Leaves would get a shot of primer, a brush stroke of Slip-Plate(or like product) and later sprayed with chassis black(or similar product).

If it's not necessary(re-arching), I don't need to reinvent the wheel. Thanks.

If they measure correctly then, yes, no re arching is necessary but I'm willing to bet the fronts will need to be done.
 
Re-arching will last for awhile, but stop and think, the reason they are sagged is fatigue and the only way you can get back to original and stay put is have them re-heat treated.
