a blank for turning to reduce vibration
from: Rob Smith
Here is a quick tip for turning between centers. If you set your
table saw blade to a 45 degree angle and rip the corners off your
blank, you will have less vibration on the lathe when you first
start turning the blank. Plus you will have less material to remove
to get your rough shape.
If your turning a bowl, plate, platter, or box, you can take a
compass and find your circle, then use your band saw to cut the
blank's corners off. Again, this helps reduce vibration, and excess
material to remove.
