Yes, there's other ways of making torsion springs; I made one by a block of word onto which I nailed a couple of tacks, and managed to wind a fine piano wire around, forming a coil ( and it worked!)🌝

I just watched this video and this is a simple way to make our springs. He is making something else but the principle is the same.

Yeah, but how do you make that T-shaped gadget he’s handling with his right hand?

For spring tension increase, just lightly hammer along the length of the brass wire.

Don’t use brass, it is the least durable option

Even half-hard brass?  I've seen Wheatstones & Jeffries from over 100 years ago still with the original and perfectly functional brass springs...

On the other hand whenever I get asked to replace a spring it is always a brass one.

The “phosphor bronze lasts 5 times as long” I got, I think, from Machinery’s Handbook, a substantial source.

Alex,

 

Whilst the elasticity (Youngs Modulus) of phosphor bronze and half Hard brass are of a range, PBronze is considerably better in fatigue performance, I am not sure but this probably reflects brass's age and work hardening characteristics.
