Well i got called off work today .....what a shame now ill just have to stay home and turn wood and work in the garage......LOL. Anyway i have an ongoing problem. When i turn my bowls the tennon breaks off very frequently. I have pictures at the bottom to show. The Tennon is about 7/8 in depth and fits into my spigot jaws on my chuck - i hollowed this one by leaving a tennon in the middle of the bowl and hollowed down to the depth i wanted. Then turned the tennon out of it....then with the scrapper showen i started to take shear cuts off the inside (freshly sharpened) and after in a short time the tennon broke off.........luckily i was on my last few cuts so ill be able to hot glue the pc back on and finish sand it.....
Wondering what others think about why this keep happening or what i can do to make it more secure...........
Im thinking that because its green wood (hemlock) that it probably stressed cracked when i was hollowing and didnt come apart because i have the tailstock up tight into the interior tennon i left on. Then after removal and still being green....and being far off the rest and deep hollowing it just cant take the stress even in light cuts..........
Thoughts ?? thanks Dan
