Pre-Seating the Turning Stock
The biggest risk with off-center turning is breaking the piece. There’s a few ways to reduce risk of breakage, and the first is to “pre-seat” the piece on all 4 turning points before you start turning.
To do this, seat the piece in the lathe along all 4 axes -- compress it deep enough for the teeth on the head stock to bite into the end-grain. Now that the teeth marks are in the wood, you won’t have to compress the piece as much when you change turning axes.
