A winder is a device that allows extremely precise control, setting up each movement in tiny increments for linear movements. It is controlled by a wheel and each 360º turn of it transforms into 1 mm of displacement generated by the screwed spindle.

At the top of this device you have mounted a Rig arm to hold puppets or elements in place. The major objective of this tool is to maximize the precision and control of a movement controlling an axis at a time. They are often used to achieve complex movements like the up and down movement in walks.

It’s ending connection is a brass square tube of 4,76mm.
