Tool Tip by Rich 3-12-18 Rich s Tool Tip Jam Chucking and the Flying Bowl Those of you that attended our March meeting got to witness an exciting ending to my demonstration. For those of you that missed the meeting, as I was making the last few scraping cuts of the demo, finishing the bottom of the bowl, it went sailing off the lathe. I had used a jam chucking arrangement with the top of the bowl pressed against a flat faceplate and held in place with the tailstock s live center. I had turned the waste from the bottom of the bowl and left only about a 5/16 center that the tailstock was pushing against. As I turned around to grab a scraper to finish dressing the bottom, the bowl went flying. So what went wrong? The obvious answer is that I turned the waste down too far. In my shop, I would have used a vacuum chucking arrangement that would have held the bowl in place in addition to the tailstock. So, in my demo, I turned the waste down like I do using the vacuum chucking method. This was a big mistake on my part. We were very fortunate that the bowl sailed over the crowed bleachers and didn t strike anyone or anything until it bounced off the floor. So, I really want to apologize to everyone for this mistake. But there was another factor that contributed to this failure of the wooden nub on the bottom of the bowl. When I jam chucked the bowl by putting pressure on the center point with the tailstock, I probably put too much pressure on the bowl. I didn t think too much about it as the bottom was thick (by the design) so I cranked it down. With the shape of the tail stock live center being a tapered point, I was effectively putting a wedge into the bottom of the bowl. When there is a lot of wood, you can do that safely, but if the bottom is thin or you turn the mounting point too small, the wedging action wins. This splits the wood and the centrifugal force of the spinning bowl allows it take off on its own. What could we do to prevent this type of accident, besides the obvious of not turning too small of a contact point and not wedging the wood too severely? We need to have a secondary means of holding the bowl in place. This is where a vacuum chucking system makes it easy but what if you don t have one? How about using some strong tape to wrap the bowl against the faceplate (or other type of jam chuck). This little insurance could save your bowl and maybe a bonk on the head if the wood did split like mine did. When we experience a mistake, it is always wise to think about what happened and how to prevent it in the future. Keep thinking about safety as you turn in your shop See you at the next meeting. 6

Central Indiana Chapter of the American Association of Woodturners April Closing words from our President We have all heard or read about the importance of using sharp tools! But one of the most critical times to stop and take the time to resharpen is when you are about to make that final cut. A freshly sharpened tool will greatly lessen the amount of sanding you will have to do, and who really enjoys sanding a lot??? See you all in May Jim If you have questions on sanding check out our library for books and dads. 8
