  • How do I keep discs from cracking??

    Yesterday I had to cut down a couple of birch trees that were damaged in the hurricane we had this past summer, and while I was at it, I sliced of a few 6" disks, mainly for wood burning. They're fresh green wood.
    How do I keep them from splitting or warping??
    They're about 1/4" to 1/2" thick....

    Jim, Soak them for several hours in denatured alcohol or methanol. Let them drip dry and wrap them in brown paper or newsprint for a couple weeks.
    If you use methanol wear glove and don't breath the fumes. That's the antifreeze in blue windshield washer fluid. You should be able to find at Auto quick Lubes. You can also find them both online .
    May the wind at you back .....

      Let us know how that works for you Jim.
      I always thought that if you leave the pith in the center it will always crack.
      When I prep wood for turning I seal both ends with a wax solution it slows the drying time down and hopefuly eliminates or slows the cracking. But I don't normaly do the entire log cross section.

        I had some cedar slabs that I tried to prevent from cracking using both methods above. It didn't work. I then tried to microwave them and that didn't work. So I did get some good smelling firewood.

        When a work lifts your spirits and inspires bold and noble thoughts in you, do not look for any other standard to judge by: the work is good, the product of a master craftsman.

          The biggest tip I can offer is don't let them dry to quickly. Quick drying tends to cause splits. Turn them often also to allow for even drying.

            Whatever way you decide to do if you are happy and your brother in law is happy it was a good idea. If you really want to be brave use it as a learning experience. Make several of them using different suggestions and see the difference....

            Well, unfortunately, I have also decided to let my subscription lapse. I've been debating it for the past couple years. It isn't so much the money, but it's more the disappointment when yet another issue has so little in it that really appeals to me. The final straw was this past Fall/Winter edition...

            Thanks to all !😀 Your comment are very good and make sense!

            My piece is 8"X8" X 1/2" thick.
            I though when I cutted the piece to do it in 1 piece or 4/5 , but after a while I decided to do it in one piece and carved it to have a 3D aspect.
            Was it a good idea.....?...

            Great designe! I would have gone a bit further than Linda, Scott and Gladefade I would cut it into more pieces to make shaping easier. Taper the clouds from right to left, taper the wings so that they are lower where they attach to the body. Taper the neck so that it looks like it is going into the...

            The never ending dilemma. I only get two magazines SSWWC and Wood carving Illustrated. Even if I don't make something in every issue there is usually something in each one that I have never tried and that will either challenge or inspire me. Yes I know that I do test cutting for them and they have occasionally...
