Tie-dye filament winder

For winding sections of nylon filament into 2 or 3 separate coils in preparation for colouring it with fabric dye. The winder handles spin on 6mm (1/4"?) coach bolts held in place with an embedded nut and one prong of the winder is attached with a wing nut on an embedded screw to facilitate easy removal of the wound filament. The other two prongs are a reasonably tight fit but can be glued in permanently if required.

The filament winder can be used hand-held - or one of the handle can be left
