Left Hand vs Right Hand Springs

Choosing the correct wind of a mechanical spring can be vital for some designs but for most optional wind is adequate.  In certain scenarios it is very important to understand how the deflection of the spring and the wind can affect the results.  Two examples are, any springs that screw or twist inside a certain apparatus--or springs that work inside each other.  These applications need to utilize the direction needed or the spring will bind and fail.  For most parts it does not matter which direction the fspring winds because the forces are going to be equivalent either way. 

Determining which direction a spring is wound is relatively easy once you learn how to see the direction.  In my experience it was always simplest just to pick the spring up observe it from one side, doesn’t matter which, and notice if the coil is moving clockwise, that would be to the right and designate a right hand wound spring.  Counter clock wise would be to the left and would designate a left hand wound spring.  Most spring machines are very flexible when it comes to wind direction and a simple setup from right hand to left hand would be a minimal hindrance.
