Dearching is a pretty simple operation using a hydraulic press and doing one
leaf at a time. Lay the leaf across a pair of steel or even wood blocks about
6-8 inches apart. You apply the pressure away from the center of the spring
in several place is retain the curve, so a little each time one side then the
other. I suggest marking the spring with chalk equal increments on each side
of the center hole for the pressure points. Start and make your height with
the largest leaf then match the others to it. I have seen Jimmy Coan do the
deal without even bothering to take the spring apart.

When I needed to lower my MGB, the spring shop to the spring and flipped it
over and then re-arced the spring. I always thought they heated it or did
it in a machine, but he does it by hand. he didn't laugh at me, but
charged
me $50 and said thanks.

> They do a pretty good job of de arching themselves all by themselves. A
spring that has some years on it carrying two up and luggage is probably a
prime candidate. Spring shops will usually laugh you out the door if you
ask
them to RE arch an English leaf spring, but should be willing to de arch.
If
you have a big enough oven, flatted it to the desired height in a device
that will hold it there and bake it. Not certain but 400 degrees F should
do
it. Allow it to cool and it should stay where you set it.
