I'm starting wood turning, I'm currently doing my second bowl. For some reason, my wood screw is getting stuck in my bowl. (both times) Whenever I try to remove my bowl, it simply does not move. It seems to spin, as if the wooden threads were stripped.
To remove the screw, I have to cut the inside of the bowl with the screw in. Once I'm far enough, the screw can get lose with residual wood around; which I remove manually. (With manual tools, pliers, chisels, etc)
Here's the chuck that I'm using.
