I posted this in another thread and thought I would share here.
Take a 1 1/2 or 2 in. 1/4 to 3/8 bolt and find a place to mount it. I have used the outside of a cabinet in the garage.
To the bolt add 2 wing nuts, and 2 rubber washers/gaskets facing each other.

When you need to respool romove the bolt from where ever and then remove one of the washers and wingnuts. Place your spool onto the bolt and replace the washer first then wingnut. Make sure the spool is touching the rubber gasket on both sides.
Place the bolt back into it's holding area and then adjust the tension on the spool with the wingnuts. Your ready to wind away conviently in your workspace
