- TL;DR Summary
- I have a spring which I am using to cushion a simple device, but it has proven to be too stiff for the purpose. Is there a way to reduce the stiffness of a spring, without making it brittle or malleable?
I have access to ovens which can achieve 550°C, which can also quench in water or poly-oil.

summary of the device:
it's a pogo-stick, anchored to the ground with a universal joint and with a plate on top. items weighing between 10-20Kg are put on top of the plate, and then gently bounced & shaken by the user. Currently, the stiffness of the spring yields almost no bounce. It will only travel about 20mm when a 12.3Kg item is placed on top. I was hoping for significantly more, in the region of 100mm. The spring is ~300mm long, from a pogo stick.
2 options I have considered are:
1: stretch it - would this yield more travel on the spring with the same force applied? I'm not 100%, as the stiffness would remain the same.
2: Heat it and either air-cool or quench it. I suspect quenching would make it harder.
I also have ovens which can achieve 900°C, and can potentially quench from them.
Any advice gratefully received!
