I have a spring seat and its springs are wayyy to stiff for my featherweight body i get 5mm of travel at the most. the springs are thick! (Velo Orange spring-seat)
Im wondering if i place the springs only into my oven and heat them to around 400F degrees, if doing that might make them more bouncy or will i just ruin them altogether?

I figure a frame-builder should know, if anyone about annealing (heat treating)

Anyone ?
thanks!
