I have ventured into making my own springs for a project. It's turning out not too difficult, and you don't need fancy tools.

Spring wire (piano wire)
Pliers
Cordless drill
small metal rod. (this determines the size of your spring

Bend about 15 to 20 mm end of wire 90 deg.
Put metal rod into drill, tighten, then slide bent end into the chuck.
Holding tight on the other end of wire with pliers, start drill slowly and let drill pull wire as you guide it.

Wire will be under tension, so carefully let it release when you finish.

It pays to make a mark on the rod for how long you want the spring so you know when to stop. Remember the spring will expend and be bigger than the rod you've wound it round.

Ends can be finished on a grinder to be made flat.

Give it a go, great fun. These springs were made from .8 mm wire, with the big one from 1.5 mm. It was my first attempt.

looks fun! do you need to set the wire with heat or anything once shaped?

No, just give plenty of resistance and it forms it.

That rod is about 5mm and spring id ended up about 8 mm.

Is there a formulae to what each piano wire will give in tension?

I guess there will be. You should see the machines they make springs on, all cnc controlled and lots of setup to make a spring, so there will be.
Last night I wanted a spring for a hammer spring. One I had was too strong and the other too weak. I have some 1.5 mm wire, and it came out just exactly what I wanted, so you can judge by squeezing them, thickness of wire and length. The other factor is diameter of course.

I imagine if you put the spring on a scale and compress it it will give you an approx rating of its compression/expasion force.
