[TheForge] Leaf Spring questions

[irontree]

Hi all,
       I got a question.  I want to flatten a leaf spring.  Jerry Allen says
that I should press it cold.  I haven't got a press but I suppose I could
find someone with one and pay them to do it....but...anyone got any ideas on
how I can do it myself.  The spring must maintain it's springyness.  I
haven't got a forge big enough or a quench tub big enough.  If I heat it in
a ground forge, flatten  it, and then mist it cold,  I still can't temper it
in my self cleaning oven cause it's too big.
Could I replace it with some other material?  I am trying to combine some
hammer designs I saw on www.anvilfire.com.  Basically I need a flat leaf
spring about 40 inches long.  Ideas are welcome
