I have attempted to turn 2 large bowls, 10-12" dia, and both have split while turning. When I get to finish turning the last 2-3 inches nearest the rim the bowls have begun to vibrate very badly. In both cases the bowl has split while I was turning it. What am I doing wrong?
Thank you,
Bob
You've got a couple pretty good guesses by MM and JL........but, it's hard to know for sure with the limited information you've supplied.
The species of wood, height, wall thickness, grain pattern, shape, etc,etc,etc, will all have their effects. What works for one set of general characteristics, may not work at all for you when any one of those physical characteristics changes.........
Off hand, here are a few possibilities:
Tools not as sharp as they could be.
RPM too high
Failure to keep supporting wood intact until no longer needed.
Attempting to remove too much wood per pass
Improper tool height, and/or presentation technique
Failure to listen to, understand, and respond to the audible indications of oscillation
.....and, more may apply!
