Thread: Greetings!

Hi everyone, I'm Peter. New to this forum. Actually, I'm new to woodturning too. I have a hundred questions but I guess I need to start with one. I've tried making small bowls (4", 6", 8") from various timbers. All of them were usable and quite decorative, (after some tweaks to sort out minor glitches.)
Getting the balance right for some irregular shaped timber was a challenge and deciding on whether to turn end grain or cross grain bowls led me to trying a segmented bowl. Of course, I decided to make a larger format bowl (16" dia. x 6" deep) because I was unaware of problems I would encounter. I quickly found that a 16" bowl is quite heavy. I had to contend with the physical size also. Turning speed was another hit and miss experiment. I hadn't thought about the fact that when the bottom radius of the bowl is spinning at low speed, the outer lip is spinning much faster. Dealing with rounding the corners of an 8sided bowl caused me some dramas with chipping, splintering, tearouts and checks. I had started to work on the outer face of the bowl first and it was progressing quite well until I had covered about half of the exterior. When I first started turning, it was a little out of balance, (as expected) and as I got to about halfway on the exterior, it was looking good balance-wise. As I got near the base of the bowl I found it was once again becoming unbalanced, (to the point where it was becoming elliptical and actually bouncing the lathe on its rubber feet.) That is what my question is about. Is it possible that the untouched interior of the bowl is now unbalanced? And if so, will I be able to complete the bowl by working on the interior? I'm a little nervous at this point, lol.
