Winding springs

[dallen]

There is one of the Workshop series of books that deal with springs its a pretty good read and gives all the math for figuring out the mandrel size with out the trial and error method that I use.

the fun part is when someone takes a coil of spring wire out of the box and cuts all the ties off of it. I use a lot of piano wire in three foot lengths from the hobby store to make springs with.
