Don't turn crappy wood!

I was given some cedar logs from a friend that his neighbor took down and he thought I could do something with them... I rough turned one log into 3 bowls and was glad to see all the character in the pieces with bark inclusions and branches going everywhere.  I had one of the bowls crack in drying and thought that I would finish another one this weekend.  It was thick but I liked it that way and was afraid that  if it was much thinner it would have problems.   I shaped and smoothed it with a sander.  I was pretty happy with it and thought I would finish the base.  so I turned it around with a jam chuck and turned up the speed and this is what was left.....

The pieces when everywhere, one off my face shield and the rest went  everywhere.  I never touched a tool to the wood, the centrifugal force took care of  it all by itself.   Below is what I found around the shop, mostly refit together....
Lessons relearned ...
1.  "Wear a face shield, even when sanding".... from a demonstrator at one of our meetings.
