I've turned about 25 bowls in my newfound wood turning hobby. I typically use a faceplate, sometimes a screw chuck to mount the blank and turn the outside. I tend to choose a recess over a tenon and I create the mark for it with calipers. Lining up both ends of it to find the center. Seems like a routine kind of thing, but when I mount the recess on the chuck to turn the inside, I have been getting a wobble in the blank right from the get go. And it's happens on a fairly consistent basis. My lathe is a new G0766 and my chuck is a new HTC125. So I'm pretty sure I can rule out a lathe or chuck hardware problem. So I presume its my inability to create a true recess as the problem. I'd appreciate any insight.
