Introduction: Make a Custom Spring

Springs are mechanical devices that store energy in the form of elastic potential energy. Springs are used to exert or maintain a force as well as absorb movement.

Materials you need:

  • Music wire
  • Pliers
  • Gloves
  • Paper
  • Tape
  • Bolt/threaded rod
  • Wire cutter

Step 1: Prepare Your Mandrel

Your mandrel should be a 1 to 2 mm, 1/32 to 1/16 of an inch bigger than the bolt/rod that the spring will go over. If you are planning to put the spring over a bolt or threaded rod, your spring should be coilled in the opposite direction that the threads are cut in.

Tape some paper onto the bolt to give it some thickness.

Step 2: Start Coilling

Chuck your mandrel into the drill. I chucked the hex head of the bolt into the drill. Insert the music wire into the chuck. Start coiling your spring, run your drill slowly. Wear gloves and hold the wire with pliers. Start by coiling once tightly, after rhat, coil the other coils with a spacing or pitch. I chose 5mm for the pitch so, i coil the springs with a spacing of 5 mm. Check that the spring is at the correct length and coil once tightly at the end.

Step 3: Done!

Trim the excess wire off, you now have a spring! It only took 1 miniute so its quite easy to make.

I hope you like it, tell me if you made some springs!

    There is usually a heating step at the end to both relax and set the spring so that it lasts longer and doesn't take a 'set' as easily.

    I have made many Springs on my 13” South Bend lathe. I made the mandrel and then wound the springs. Some were extension and some were compression. I made them up to 1/8” wire diameter. They were easy to make after you practiced awhile. There is a spring chart you can use to determine the mandrel size with the size wire you are to use. There is also a special pair of pliers you can use to form the ends into loops or hooks. Spring cutting pliers are also very handy to have. You can buy the spring or music wire in rolls or precut lengths. Good luck and have fun with Springs.
