Chris Chris' Tips
Some people want a chuck that can hold larger diameters. 4" chucks work well on the mini lathe, but it is possible to use a 5" chuck on the mini lathe.

Mount this chuck on a mini lathe with one of our chuck adapters. Or purchase a chuck with an adapter already mounted.

Here are instructions for centering work in a 4-jaw chuck. It's easy if you follow this procedure.
