Depends on what you're trying to dry.  Logs and half logs you can paint the end grain with a wax sealer such as Anchor-Seal and allow them to dry for a couple of years.  If your turning rough outs, use the sealer on both inside and outside and let it sit for 6-9 months to dry.  You may find that it needs to sit longer, in which case you re-coat and let the piece dry a while longer.  You can also turn green wood to finish, sand, boil, allow to dry (which will leave the piece warped) and then sand the "hairs" by hand with a fine grit sandpaper.

There you have it in a nut shell.  Any questions?  Clear as mud I'm sure.

Thank you dear RevDoug!
I turn bowls from green wood, but the complete bowl always crack out. I heard about different drying process (microwave, paper bag, etc...) I interested about them.

another thing: what do you mean about "boil"-ing? Shocked

What type of wood?
Where do you live?
How do you store your blanks?


Once the bowl is roughed out, seal the end grain with Anchor-Seal and allow to dry 3-12 months. Remount on the lathe and finish turning.

In order to improve your chances of getting a finished bowl out of a green log you can pay attention to the growth rings on the end of the log when you are making your initial cuts to split the log.  If the log is oval in cross section it can be tempting to cut it so as to yield the largest diameter bowl blank, but that may not be the best way to go.  You should cut the log along a line that has the pith in the middle and the growth rings evenly spaced on each side of the pith.  That will bring the forces acting on the wood as it dries more into balance and reduce checking and cracking in your rough turned bowls.  Bill Grumbine explains it well in his first video, which gave me the idea for this simple sketch:

You will have more chance of getting a finished bowl without cracks if you cut along the green line rather than the red one.

Good Luck!

Boiling = placing the piece in a pot of water, applying heat so that the water boils (as if you are making soup).

if you turn green wood to finish thickness, there are still shrinkage forces at work within the wood.  As the wood dries it will try to tear itself apart.  The boiling will soften the fibers within the wood and will allow the bound water in the wood to be released.  The process will leave the wood wet with unbound water which will evaporate out and off faster with out the wood checking.  In other words, it is just one way of drying wood.

The theory about boiling is that you boil the sap out and replace it with water which evaporates more easily.  At least I think that's the theory???

That's about right Leo, but I've been told that it's really a bit more involved than that.  All I know is that it can be done with great success.

What about using alcohol to dry the rough-turned piece?  The article on the website above doesn't open.   Does anyone have experience with alcohol?  (For drying wood.  I have plenty enough experience with other uses)

That's Dan's (WindsorWoods) method.  He explained it in detailed.  He uses DNA, denatured alcohol.
