Hi, a few months ago I rough turned my first two natural edge bowls from a chunk of maple. I did what I normally do and left the walls about 1" thick while it dried over a couple months.
When I went to get the bowls to finish them, I noticed they had warped an extreme amount along the "length" ... so they are now oval shaped. I put one on the lathe and it had warped so much that I couldn't even get it back to round without completely chewing away the two "long sides". They were down to about 1/4" and I still had barely hit the other two sides.
Is this normal for natural edge bowls? Should I be roughing and finishing them all in one session? Even with the extreme warp, there are no cracks at all. I really don't want to do any more until I find out the strategy I should be using as it appears to be different the other standard bowls I've done in the past.
