Wound my own torsion and compression springs by hand.

Also, the first few weren't pretty but I kept at it until the correct number of coils fit into the correct length with fairly even coil spacing.

Stress relieved them in the oven at 500F for an hour and let them slowly cool. They're not "commercial perfect" looking, but they fall within the correct range, and they weren't available commercially.

0.043 music wire doesn't look very thick until you try to get 16 coils of it into a free length of 1 5/8".
