But I also discovered, also several years ago, that a wood lathe can
be a sleeping dog. I mounted a glued up rather heavy piece of stock
made from 2x4 to make a simple over sized dowel for a project. I
started the machine at about 300rpm to round it up and after about ten
seconds I was hit smack in the middle of the full face shield. Thank
goodness I was wearing it. I never saw the stock leave the lathe. I
remember impact and a stinging sensation. I looked down and the
work-piece was draped across my arms that were still extended in the
working position; and I realized there was blood on the shield. The
piece had split out allowing it to fly out of the lathe and as best I
could figure it bounced off of the bed and then up to the shield. The
flexible face shield had deflected into my face striking my glasses.
The stinging sensation and blood were from the left nose-piece and the
rims of my glasses scraping my nose and eyebrow. Minor abrasions but
thank god I was wearing the shield. two of the four snaps that attach
the shield to the hood were busted loose. Scared the #$@% out of me
and I never mounted another work piece without a good inspection.

It didn't take long to learn to always wear a face shield (get a good
one) when turning the lathe on. I've been hit in the shield twice since
getting my lathe.

I saw pictures of a grinder wheel break up, and a description of what was
going on. That was enough for me to decide not to stand near the grinder
as it was spinning up. Imagine a machine throwing rocks at 3600 RPM.


Bill hit it on the head. The brain. The table saw accident was a
moment of carelessness after I turned the machine off. The lathe
incident might not have been avoidable. But as I said, I always check
my stock carefully before mounting it on the lathe.

Yeah - I approach the grinder pretty much as I approach the table saw. I try to keep my body away from the plane of the wheel. Even there you can get buggered.
