[SEL] Making a spring

[David Everett]

Curt

One way is to have a screw thread bar held in the chuck with a cross hole to take the end of the
spring wire.  Set the carriage feed to the same pitch as the thread.  In the tool holder have a
piece of steel bar with a hole drilled through it the same size as the spring wire so that the
wire is fed through in a controlled manner onto the screw thread bar.  Put a grub screw down
through the wire feeder to press against the spring wire and adjust the pressure to keep it tight.
 If you are being posh, the grub screw could have a brass slug so that it is brass rubbing against
the steel instead of the hard steel.

Wear stout gloves - that wire will cut through your hand with consummate ease.

Hope this helps
