It's a man thing, right?
For starters, I'm new to turning. Have watch videos and read all I could find on the subject and have asked a few questions here on SMC.
Today I turned my first bowl and it was shaping up nicely. I put on my Nova cole jaws to finish the bottom. While cutting off the tenon, the bowl launched out of the jaws, hit my fluorescent light which exploded into a million and one pieces and pretty much made a mess of the shop.
Fortunately I was no worse for wear. My face shield blocked any glass from hitting me.
The reason for the above title is because I failed to read all of the instructions on the jaws or I plumb forgot what I read. First off, the jaws clearly state 600 RPM's. I was running at a little over 900. Number 2, the bowl has straight sides and did not have a negative flair on the lip.
I now know that some of you turners will use a donut type chuck on some other type of compression clamp to solve this problem.
I was very fortunate that the bowl was not damaged in any way that I can see. There was no catch to cause this, maybe just the two reasons I stated above.
I wound up putting my tool rest close to the bottom of the bowl and also brought my tailstock in to prevent it was launching again.
LESSON LEARNED!
