Warped Maple Bowl

Just posting this maybe for someone else like me who is just starting out.I turned this maple bowl last week,and was letting it dry so I could finish.I went out of town this last weekend and when I got back,it had warped on me,so I went to my local hardware store,and bought a large adjustable band,put the bowl upside down in warm water to soak for about 30 minutes,removed,put band on ,adjusted so it was firm on the bowl,them got my wife to find me a bowl to just fit inside,now going to let dry for a few days,and see what happens.Don't know if this is correct to do this,but seem to be logical at the time;Mack

I'm curious to see how this works out for you...

I believe that we rough turn thick, so's we can turn out any warpage...
The warp is the anti-check in the wood, so-to-speak.

Let's see what the experts think...

Beautiful piece of wood, though!

...ever notice how "I'm sorry" and "I apologize" mean the same thing, unless you are at a funeral..?

did you put it in a paper bag to dry after turning?if not that may be why it warped so bad.

Big Mack,
If you are going to rough turn a bowl that size, leave the walls and bottom about 3/4" thick. The general rule of thumb is to leave the walls 10% of the diameter. Put it in a paper shopping bag and set it aside out of the sun in a cool place and let it dry for a few months before finishing it. You could also take a blank like that and finish turn the bowl in one sitting while the blank is not dry. You have to get the walls fairly thin, about 1/8" - 3'16". It will warp into a gravy boat, but shouldn't crack. They actually look pretty cool that way.

That's what happens to wood as it dries quickly.
The alternative is the cracking that we call "checking"...

The idea is to allow the wood to dry more slowly/evenly, decreasing the movement, as Mike/Robert describe above...

Just because I know this doesn't mean I do it!

A good bit of my stuff has a nice "oval" to it
