Don't try this one at home. Leave it to the professional safety officers to prove that this is dangerous and not a smart thing to do. The rimmed bowl was not very large and had almost coasted to a stop. But, the mesquite bowl still had plenty of wood along with the hefty chuck, lathe spindle, pulleys, and motor armature all contributing meant that it still had a good amount of momentum. I mentioned that it had almost coasted to a stop -- in this instance, almost meant that it probably would have come to a full stop in another nine or ten seconds ... fifteen at the most. I do not usually make rimmed bowls, but this one was a special request from the lady who tells me that my turnings look good enough to display in the house (most of the time) so it was put on the front burner. Anybody who has ever turned mesquite knows that borers like it as much as woodturners do. The abundance of tunnels frequently presents turners with an opportunity to collaborate with the bugs -- or else waste away lots of wood. This particular chunk of wood looked like it had some tunnels in the heartwood that might work as a collaborative piece so I decided to include some of the bug work in the piece. After a bit, it became apparent that the edge of the rim was a little too ragged with tunnels to work well so some of those tunnels needed to go so that the rim would have a nice smooth edge. However, I wanted to be careful to not reduce the width of the rim more than absolutely necessary so I made a mental note of where "absolutely necessary" existed. This would be a good time to mention that pencil marks are often better than memory for making accurate notes such as this. One other thing worth mentioning is that your hand is not a very good substitute for brake pads. It turned out that while using my hand brake to stop the spinning bowl that I learned that not all of the bug tunnels had been removed from the rim - see the attached snapshot. That little hook shaped notch caught the webbing between my thumb and index finger and ripped a ragged gash about 3/8" deep and a bit more than 1/2" long a it passed through my hand and slowing down only slightly. If there is any good news, it is that the bowl was unharmed in this unfortunate encounter. This was my first and hopefully only lathe injury to draw blood from contacting spinning wood. I have had a couple bad cuts from very sharp hand tools (a woodcarver's chisel not being used properly and contact with an inappropriately stored bowl gouge -- sitting pointy end up in a five gallon bucket). I learned something worth remembering about pain -- being cut with a super sharp tool is nearly painless for the first hour or two. The pain starts later after being sewn back together by the ER doctor. However, a ragged gash made by a relatively rough edged chunk of wood hurts like Hell right from the get-go! I wrapped the cleanest filthy shop towel that I could find around my hand and headed to wash up the wound. Somehow after washing up the wound, I managed to simultaneously keep pressure on while applying several butterfly closures and a pressure pad. Amazingly everything healed very nicely in about ten days with no missing pieces in the jigsaw puzzle that was my right hand. So, what are the lessons to be learned? Here are a few things that come to mind: In wood vs. flesh, wood comes out ahead every time. I could not find even a slight bit of damage to the wood. Wood does not need to be sharp to tear through flesh. The pain of torn flesh is incredibly intense. It hurt so much that I could not even manage to utter any oaths against the wood. I don't plan on installing brake pads on my hands so that means that a spinning turning can just coast to a stop on its own and I will find other things to amuse myself while waiting for the lathe to stop turning. Would leather gloves have helped? I think that they might have made things worse -- here is why: I believe that the glove would have been hooked and caused my hand to slam against the tool rest -- possibly dislocating or breaking one or more fingers. That type of injury with ligament damage is very slow to heal -- taking at least a year and probably never regaining full function. My woodturning club bestows a good-natured "Safety Officer" distinction to members who have injured themselves as way to encourage safe turning by sharing personal experiences. It is not the kind of recognition that members intentionally seek, but we willingly share our lessons learned so that hopefully we all don't have to go through the same mishaps while learning the wrong way to do things.
