    Default Building Boxes: Any Special Treatment of Knots?

    I'm wondering what advice you might have for treatment of knots when building gear. Some of the wood I have is pretty knotty, but they're sound. Do you just paint them, or do you have a particular approach to keeping them solid?

    Thanks,

    Adam

    When you cut up the wood, keep knots away from edges and ends of pieces. Milling and assembly will be much easier.

    I like the construction adhesive idea. I usually put a good coat of Titebond III on the knots before priming and painting.

    Definately (use good quality) primer then paint two coats. Typically they will not fall out unless the are loose from the start.
    Loose ones... Titebond glue.

    I tried to trim away knowts when ripping boards down and avoid getting them on the cut ends, so that assembly would be easier. The knotted areas soak up a lot more paint, so i just kept applying paint until they wouldn't soak up any more. I like the idea of squishing in some glue before painting. I wish i would have done that.

    I used latex, as this is what I had on hand, but while looking through old posts, I found comments in a few places indicating that the use of oil based was fine. I think the oil based is overlooked becasue there are no monetary savings, and it is harder to clean up, requiring chemicals, also if sprayed, it nearly always requires a thinner to be used. Furthermore, Home depot doesn;t havea shelf of "oops" oil paints
