Thought I would show you my 'press button' automatic woodturning chuck... just press the button and the jaws open or close...
If I was selling it I would say something like, this is the next big step in the development of woodturning equipment...
- With just the press of the button it opens and closes the chuck jaws
- It provides a fast automatic one handed chuck operation
- It can be easily retrofitted to most modern chucks
- Can finely adjust the contraction and expansion tension applied to blanks
- You will no longer have to go looking to find the chuck key in the shavings
- Reduces the risk of not seeing that you have left the key in the chuck
And the good news is that you probably already have one... at no extra cost!

I've dedicated my old 12v battery drill for this and have it within reach next to the lathe. It considerably speeds up the opening and closing of the jaws on scroll chucks and the tension applied to dovetails and tenons is set with the screw dial on the drill.
