    Another Question DNA

    If in fact the DNA displaces the water in a rough turned bowl would it be possible to then accelerate the drying process? Maybe a heat box with a light bulb like an incubator. I apologize if this has already been answered. I did a quick search, but didn't see it.

    I would avoid the combo of extra heat and evaporating DNA. No experience doing it, but the idea makes me a little nervous.

    If I remember correctly that is how volcano explosions are caused.

    rapid drying DNA

    Ah, yes. In the back of my feeble mind, I knew there was something I wasn't thinking about. This may result in a too dry situation. Instead of an Ash bowl, it may become just a pile of Ashes. Thanks for the reminder.

    Ray,
    Even after the DNA soak, you will often see cracking if you don't slow the process of drying your piece via a paper bag or a wrap of newspaper, etc.

    There was an interesting article in Woodturning Design about using a refrigerator with a light bulb as a "kiln" for bowl blanks. Didn't use DNA, but it sure accelerated the drying process.

    Dick hit the nail on the head. Drying should be a slow process. Even if it was safe to do (which it is not) the extra heat will probably ruin it by drying it way to fast.

    I usually double paper bag it and weigh it every once in awhile till it stops losing weight. Have not lost a piece that way yet......so far..

    And on average this is how long?

    Depending on the size of the piece, type of wood, basement conditions, I would have to say 2-3 months as an average. Some may be ready faster but I never rush it.

    Ray,
    More important than time is the process where the piece stops losing weight.
    Some woods dry much quicker than others. I have found that when the wood stops losing weight 3-4 days in a row, it is usually stable enough to start finish turning. This can be in as little as 12-14 days or as much as a 30-60 days. Weighing the wrapped piece will give you the clue as when to finish it.
    Regards, Ken
