Mini Lathe Tooling
The 3-jaw chuck that comes with the mini lathe is the correct work holding device for most work done on the mini lathe. When you want to work on larger work pieces, rectangular work pieces, or work to a precision you can't achieve with a 3-jaw chuck, then another chuck option is appropriate.
4-jaw chucks have several advantages. Because each jaw is independently adjustable, you can center your work piece more accurately than you can in a 3-jaw self-centering chuck. And, you can easily center square and rectangular stock in a 4-jaw chuck.
If you simply want to turn work pieces that are too big for the standard 3-jaw chuck, then a 4-jaw or larger 3- or 4-jaw chuck is in order.
The mini lathe is designed for a 3" chuck. You need an adapter to mount a 4" chuck on the mini lathe. The adapter bolts onto the lathe's spindle flange and provides the larger bolt circle required for a 4" chuck.
