LDD- Am I Doing This Correctly???

Having had a rash of rough turned bowls crack recently, I want to try the LDD route. What I believe I am supposed to do is turn the green and wet wood to roughed out bowls leaving a thickness of about 10% of the diameter of the bowl. I then soak the roughed out bowls in a solution of

1:1 LDD and water for 24hrs or so. I then will shake off the excess solution and put them in doubled brown paper bags to dry. When dried and hopefully uncracked, turn them to the finished product. Is this correct??? Also, the bowls that have been cracking lately I believe to be red oak. Your advice is appreciated.

Any of the methods you are combining should do it, though if you just go with the soak, you'll need to do "the dance."

What sort of LDD are you guys using??? and what sort of activity does it have in terms of percentage actives??

In a word, no. You have to turn the wood immediately after soaking it. Drying it is causing the cracking. Turn it to the final size after soaking and put the finish on immediately. If you have to stop tuning or wait berfore fioishing, put it back into the LDD. LDD keeps it from cracking before turning, it has no effect afterwards, you've turned it all off the bowl. Soak it in block form or rough turned form if it hasn't had any time to dry before you start turning it, or at all intervals in the process before finishing, but if tyou let the wood dry it will crack. I hope that makes sense.

My experience has been the same as Tony's. I also can't remember the last time I had a crack. A thick bottom and uneven walls equals cracks. If I can't finish a bowl I just wrap a plastic bag around it.

Thanks for all the input, especially the advice about leaving the bottom too thick.. My only question is how do you finish a green wood bowl immediately after it is soaked then final turned. How do you sand it, and since I mostly use spray lacquer, will the final turned green wood react adversely to the lacquer???

By the time you have final turned and sanded, there will be little "moisture" left on the object. Just apply whatever finish you have immediately after the final turning and sanding. I suggest you not let it "air dry" as that could well crack or warp. I have had no problem with any finish being affected by the damp wood. The only exception that I heard from another turner was not to use waterbased finishes.
