Does anyone have any experience turning with a vacuum chuck? If so, can you comment in how securely they hold the wood on the lathe. Perhaps you could tell me how big of a piece of wood you would be comfortable turning with a 3” and/or a 6” vacuum chuck.

Do you use the vacuum chuck for roughing or just for shaping and finishing?

Thanks in advance for any input I receive.

I dont have one but I’m pretty sure that the bigger the…ummm…atachment you use, the more suction it has. I’ve heard stories of people breaking bowls because of using to much suction, so I dont think you have to worry about it holding the wood securely. Have a look at THIS article on homemade vaccum chucks.

An alternative is a DOUGHNUT CHUCK or a longworth chuck. Or you can buy commercially made Cole Jaws
